The effects of glucocorticoids and progesterone on hormone-responsive human breast cancer in long-term tissue culture. (1/7402)
Glucocorticoids, at physiological concentration, inhibit cell division and thymidine incorporation in three lines of human breast cancer maintained in long-term tissue culture. At steroid concentrations sufficient to inhibit thymidine incorporation 50%, little or no effect is seen on protein synthesis 48 hr after hormone addition. All three of these lines are shown to have glucocorticoid receptors demonstrable by competitive protein binding assays. Receptors are extensively characterized in one line by sucrose density gradient analysis and binding specificity studies. Good correlation between receptor-binding specificity and biological activity is found except for progesterone, which binds to glucocorticoid receptor but is noninhibitory. Cross-competition and quantification studies demonstrate a separate receptor for progesterone. This receptor has limited binding specificities restricted largely to progestational agents, whereas the glucocorticoid receptor bound both glucocorticoids and progesterone. Two other human breast cancer lines neither contain glucocorticoid receptor nor are inhibited by glucocorticoids. It is concluded that in some cases glucocorticoids can directly limit growth in human breast cancer in vitro without requiring alterations in other trophic hormones. (+info)Expression of nitric oxide synthase in inflammatory bowel disease is not affected by corticosteroid treatment. (2/7402)
AIM: To examine the effect of corticosteroid treatment on the expression of inducible nitric oxide synthase (iNOS) in the colon of patients with inflammatory bowel disease. METHODS: Four groups of patients were studied: (1) ulcerative colitis treated with high dose corticosteroids (six patients, 10 blocks); (2) ulcerative colitis patients who had never received corticosteroids (10 patients, 16 blocks); (3) Crohn's disease treated with high dose corticosteroids (12 patients, 24 blocks); (4) Non-inflammatory, non-neoplastic controls (four patients, six blocks). Full thickness paraffin sections of colons removed at surgery were immunostained with an antibody raised against the C terminal end of iNOS. Sections were assessed semiquantitatively for the presence and degree of inflammation and immunoreactivity for nitric oxide synthase. RESULTS: Cases of ulcerative colitis and Crohn's disease with active inflammation showed strong staining for nitric oxide synthase. The staining was diffuse in ulcerative colitis and patchy in Crohn's disease, in accordance with the distribution of active inflammation. Staining was seen in epithelial cells and was most intense near areas of inflammation such as crypt abscesses. Non-inflamed epithelium showed no immunoreactivity. Treatment with corticosteroids made no difference to the amount of nitric oxide synthase. CONCLUSIONS: Expression of nitric oxide synthase is increased in both ulcerative colitis and Crohn's disease and appears to be unaffected by treatment with corticosteroids. Disease severity necessitated surgery in all the cases included in this study, regardless of whether or not the patients had received long term corticosteroid treatment. It seems therefore that a high level of iNOS expression and, presumably, production of nitric oxide characterise cases which are refractory to clinical treatment; this suggests that specific inhibition of the enzyme may be a useful therapeutic adjunct. (+info)Production of prostaglandin f2alpha and its metabolite by endometrium and yolk sac placenta in late gestation in the tammar wallaby, Macropus Eugenii. (3/7402)
In this study, we investigated production of prostaglandin (PG) F2alpha and its metabolite, PGFM, by uterine tissues from tammar wallabies in late pregnancy. Endometrial explants were prepared from gravid and nongravid uteri of tammars between Day 18 of gestation (primitive streak) and Day 26.5 (term) and were incubated in Ham's F-10 medium supplemented with glutamine and antibiotics for 20 h. PGF2alpha and PGFM in the medium were assayed by specific, validated RIAs. Control tissues (leg muscle) did not produce detectable amounts of either PG. Both gravid and nongravid endometria secreted PGF2alpha, and production increased significantly in both gravid and nongravid uteri towards term. PGFM was produced in small amounts by both gravid and nongravid uteri, and the rate of production did not increase. Neither oxytocin nor dexamethasone stimulated PG production in vitro in any tissue at any stage. Thus, the surge in peripheral plasma PGFM levels seen at parturition may arise from increased uterine PG production, but further study is needed to define what triggers this release. (+info)CCAAT/enhancer-binding protein beta is an accessory factor for the glucocorticoid response from the cAMP response element in the rat phosphoenolpyruvate carboxykinase gene promoter. (4/7402)
The cyclic AMP response element (CRE) of the rat phosphoenolpyruvate carboxykinase (PEPCK) gene promoter is required for a complete glucocorticoid response. Proteins known to bind the PEPCK CRE include the CRE-binding protein (CREB) and members of the CCAAT/enhancer-binding protein (C/EBP) family. We took two different approaches to determine which of these proteins provides the accessory factor activity for the glucocorticoid response from the PEPCK CRE. The first strategy involved replacing the CRE of the PEPCK promoter/chloramphenicol acetyltransferase reporter plasmid (pPL32) with a consensus C/EBP-binding sequence. This construct, termed pDeltaCREC/EBP, binds C/EBPalpha and beta but not CREB, yet it confers a nearly complete glucocorticoid response when transiently transfected into H4IIE rat hepatoma cells. These results suggest that one of the C/EBP family members may be the accessory factor. The second strategy involved co-transfecting H4IIE cells with a pPL32 mutant, in which the CRE was replaced with a GAL4-binding sequence (pDeltaCREGAL4), and various GAL4 DNA-binding domain (DBD) fusion protein expression vectors. Although chimeric proteins consisting of the GAL4 DBD fused to either CREB or C/EBPalpha are able to confer an increase in basal transcription, they do not facilitate the glucocorticoid response. In contrast, a fusion protein consisting of the GAL4 DBD and amino acids 1-118 of C/EBPbeta provides a significant glucocorticoid response. Additional GAL4 fusion studies were done to map the minimal domain of C/EBPbeta needed for accessory factor activity to the glucocorticoid response. Chimeric proteins containing amino acid regions 1-84, 52-118, or 85-118 of C/EBPbeta fused to the GAL4 DBD do not mediate a glucocorticoid response. We conclude that the amino terminus of C/EBPbeta contains a multicomponent domain necessary to confer accessory factor activity to the glucocorticoid response from the CRE of the PEPCK gene promoter. (+info)Analysis of Chinese herbal creams prescribed for dermatological conditions. (5/7402)
OBJECTIVE: To determine whether Chinese herbal creams used for the treatment of dermatological conditions contain steroids. DESIGN: 11 herbal creams obtained from patients attending general and paediatric dermatology outpatient clinics were analysed with high resolution gas chromatography and mass spectrometry. SETTING: Departments of dermatology and clinical biochemistry. MAIN OUTCOME MEASURE: Presence of steroid. RESULTS: Eight creams contained dexamethasone at a mean concentration of 456 micrograms/g (range 64 to 1500 micrograms/g). All were applied to areas of sensitive skin such as face and flexures. CONCLUSION: Greater regulation needs to be imposed on Chinese herbalists to prevent illegal and inappropriate prescribing of potent steroids. (+info)Inactivation of the winged helix transcription factor HNF3alpha affects glucose homeostasis and islet glucagon gene expression in vivo. (6/7402)
Mice homozygous for a null mutation in the winged helix transcription factor HNF3alpha showed severe postnatal growth retardation followed by death between P2 and P12. Homozygous mutant mice were hypoglycemic despite unchanged expression of HNF3 target genes involved in hepatic gluconeogenesis. Whereas insulin and corticosteroid levels were altered as expected, plasma glucagon was reduced markedly in the mutant animals despite the hypoglycemia that should be expected to increase glucagon levels. This correlated with a 70% reduction in pancreatic proglucagon gene expression. We also showed that HNF3alpha could bind to and transactivate the proglucagon gene promoter. These observations invoke a central role for HNF3alpha in the regulatory control of islet genes essential for glucose homeostasis in vivo. (+info)Antisense downregulation of a mouse mammary tumor virus activated protooncogene in mouse mammary tumor cells reverses the malignant phenotype. (7/7402)
Activation of the protooncogene Wnt-1 by insertion of the mouse mammary tumor virus (MMTV) is known to cause mammary tumors in mice. Wnt-1 expression in mammary glands has been postulated to confer direct local growth stimulation of mammary epithelial cells leading to their acquisition of a preneoplastic state. Wnt-1 expression also induces morphological alterations in cultured normal mammary cells. However, it has not been determined whether or not transformed mammary cells require continuous Wnt-1 expression for their ability to form tumors in vivo. To address this question, we constructed antisense and sense Wnt-1 expression vectors containing a synthetic promoter composed of five high-affinity glucocorticoid response elements (GRE5). This promoter is at least 50-fold more inducible by dexamethasone than the promoter contained in the long terminal repeats of MMTV. The vectors were introduced into a mouse mammary tumor cell line (R/Sa-MT) that expresses high levels of endogenous Wnt-1 mRNA and forms rapidly growing tumors when transplanted into syngeneic hosts. Of the 12 stably transfected cell lines established (9 with antisense and 3 with sense constructs), 2 antisense cell lines (R/Sa-MT/antisense) and 1 sense cell line (R/Sa-MT/sense) were examined for inducibility by dexamethasone of antisense and sense Wnt-1 RNAs, changes in endogenous Wnt-1 RNA expression, and changes in cell morphology. The growth patterns of the cells in vitro and in vivo were also examined. Our results show that (1) the levels of the expression of endogenous Wnt-1 mRNA and protein were reduced significantly (>80%) in those cells (R/Sa-MT/antisense) that expressed antisense Wnt-1 RNA at high levels following exposure to dexamethasone, compared to the R/Sa-MT/sense and R/Sa-MT control cells and (2) transplantation of the R/Sa-MT/antisense cells produced smaller tumors ( approximately 0.2 cm in 16 weeks) compared to the tumors ( approximately 2.0 cm in 8 weeks) that were produced by the R/Sa-MT/sense and R/Sa-MT cells. We therefore suggest that Wnt-1 expression is required not only for the transformation of normal mammary cells into tumor cells, but also for the maintenance of their tumorigenicity. (+info)Role of iNOS in the vasodilator responses induced by L-arginine in the middle cerebral artery from normotensive and hypertensive rats. (8/7402)
1. The substrate of nitric oxide synthase (NOS), L-arginine (L-Arg, 0.01 microM - 1 mM), induced endothelium-independent relaxations in segments of middle cerebral arteries (MCAs) from normotensive Wistar-Kyoto (WKY) and hypertensive rats (SHR) precontracted with prostaglandin F2alpha (PGF2alpha). These relaxations were higher in SHR than WKY arteries. 2. L-N(G)-nitroarginine methyl ester (L-NAME) and 2-amine-5,6-dihydro-6-methyl-4H-1,3-tiazine (AMT), unspecific and inducible NOS (iNOS) inhibitors, respectively, reduced those relaxations, specially in SHR. 3. Four- and seven-hours incubation with dexamethasone reduced the relaxations in MCAs from WKY and SHR, respectively. 4. Polymyxin B and calphostin C, protein kinase C (PKC) inhibitors, reduced the L-Arg-induced relaxation. 5. Lipopolysaccharide (LPS, 7 h incubation) unaltered and inhibited these relaxations in WKY and SHR segments, respectively. LPS antagonized the effect polymyxin B in WKY and potentiated L-Arg-induced relaxations in SHR in the presence of polymyxin B. 6. The contraction induced by PGF2alpha was greater in SHR than WKY arteries. This contraction was potentiated by dexamethasone and polymyxin B although the effect of polymyxin B was higher in SHR segments. LPS reduced that contraction and antagonized dexamethasone- and polymyxin B-induced potentiation, these effects being greater in arteries from SHR. 7. These results suggest that in MCAs: (1) the induction of iNOS participates in the L-Arg relaxation and modulates the contraction to PGF2alpha; (2) that induction is partially mediated by a PKC-dependent mechanism; and (3) the involvement of iNOS in such responses is greater in the hypertensive strain. (+info)Glucocorticoids are a class of hormones produced by the adrenal gland that regulate glucose metabolism and have anti-inflammatory and immunosuppressive effects. They are commonly used in medicine to treat a variety of conditions, including: 1. Inflammatory diseases such as rheumatoid arthritis, lupus, and asthma 2. Autoimmune diseases such as multiple sclerosis and inflammatory bowel disease 3. Allergies and anaphylaxis 4. Skin conditions such as eczema and psoriasis 5. Cancer treatment to reduce inflammation and suppress the immune system 6. Endocrine disorders such as Cushing's syndrome and Addison's disease Glucocorticoids work by binding to specific receptors in cells throughout the body, leading to changes in gene expression and protein synthesis. They can also increase blood sugar levels by stimulating the liver to produce glucose and decreasing the body's sensitivity to insulin. Long-term use of high doses of glucocorticoids can have serious side effects, including weight gain, high blood pressure, osteoporosis, and increased risk of infection.
Dexamethasone is a synthetic glucocorticoid hormone that is used in the medical field as an anti-inflammatory, immunosuppressive, and antipyretic agent. It is a potent corticosteroid that has a wide range of therapeutic applications, including the treatment of allergic reactions, inflammatory diseases, autoimmune disorders, and cancer. Dexamethasone is available in various forms, including tablets, injections, and inhalers, and is used to treat a variety of conditions, such as asthma, COPD, rheumatoid arthritis, lupus, multiple sclerosis, and inflammatory bowel disease. It is also used to treat severe cases of COVID-19, as it has been shown to reduce inflammation and improve outcomes in patients with severe illness. However, dexamethasone is a potent drug that can have significant side effects, including weight gain, fluid retention, high blood pressure, increased risk of infection, and mood changes. Therefore, it is typically prescribed only when other treatments have failed or when the potential benefits outweigh the risks.
Receptors, Glucocorticoid are proteins found on the surface of cells in the body that bind to and respond to hormones called glucocorticoids. Glucocorticoids are a type of steroid hormone that are produced by the adrenal gland in response to stress or injury. They play a role in regulating a wide range of physiological processes, including metabolism, immune function, and inflammation. When glucocorticoid hormones bind to their receptors, they trigger a cascade of chemical reactions within the cell that leads to changes in gene expression and cellular function. This allows the body to respond to stress and maintain homeostasis.
Mifepristone is a medication that is used to induce abortion. It is a synthetic steroid that works by blocking the action of progesterone, a hormone that is necessary for a pregnancy to continue. Mifepristone is typically used in combination with another medication, such as misoprostol, to induce abortion. It is usually taken orally, but it can also be administered by injection. Mifepristone is typically used in the first trimester of pregnancy, but it can also be used later in pregnancy to induce labor. It is considered to be a safe and effective method of abortion when used under medical supervision.
Corticosterone is a steroid hormone produced by the adrenal cortex in response to stress. It plays a key role in the body's stress response and helps regulate metabolism, immune function, and blood pressure. Corticosterone is also involved in the development and maintenance of bone tissue, and it has anti-inflammatory effects. In the medical field, corticosterone is used to treat a variety of conditions, including adrenal insufficiency, allergies, and autoimmune disorders. It is available as a prescription medication and is typically administered orally or by injection.
Adrenalectomy is a surgical procedure in which one or both of the adrenal glands are removed. The adrenal glands are small, triangular-shaped glands located on top of the kidneys. They produce hormones such as cortisol, aldosterone, and adrenaline, which play important roles in regulating various bodily functions. There are several reasons why an adrenalectomy may be performed, including: 1. Adrenal gland tumors: Benign or malignant tumors of the adrenal gland can cause hormonal imbalances and may need to be removed. 2. Hyperaldosteronism: This condition is caused by an overproduction of aldosterone, which can lead to high blood pressure. Adrenalectomy may be performed to remove the affected adrenal gland. 3. Cushing's disease: This condition is caused by an overproduction of cortisol, which can lead to weight gain, high blood pressure, and other symptoms. Adrenalectomy may be performed to remove the affected adrenal gland. 4. Pheochromocytoma: This is a rare tumor of the adrenal gland that can cause high blood pressure and other symptoms. Adrenalectomy may be performed to remove the affected gland. Adrenalectomy is typically performed under general anesthesia and may be done laparoscopically or through a traditional open incision. The procedure may take several hours, and patients may need to stay in the hospital for a few days following the surgery.
Hydrocortisone is a synthetic glucocorticoid hormone that is used in the medical field to treat a variety of conditions. It is a potent anti-inflammatory and immunosuppressive agent that can help reduce inflammation, swelling, and redness in the body. Hydrocortisone is also used to treat conditions such as allergies, asthma, eczema, and psoriasis, as well as to reduce the symptoms of adrenal insufficiency, a condition in which the body does not produce enough of the hormone cortisol. It is available in a variety of forms, including oral tablets, topical creams, and injections.
11-beta-Hydroxysteroid Dehydrogenase Type 1 (11β-HSD1) is an enzyme that plays a crucial role in regulating the levels of cortisol, a hormone produced by the adrenal gland. It is expressed in various tissues throughout the body, including the liver, muscle, adipose tissue, and brain. The primary function of 11β-HSD1 is to convert inactive cortisone to its active form, cortisol. This conversion occurs in the liver and adipose tissue, where 11β-HSD1 is highly expressed. Cortisol is a key hormone involved in the body's stress response and plays a role in regulating metabolism, immune function, and blood pressure. In addition to its role in cortisol metabolism, 11β-HSD1 has also been implicated in the development of various diseases, including obesity, diabetes, cardiovascular disease, and depression. For example, increased activity of 11β-HSD1 in adipose tissue has been linked to insulin resistance and the development of type 2 diabetes. Similarly, increased activity of 11β-HSD1 in the brain has been linked to depression and anxiety. Overall, 11β-HSD1 is a critical enzyme involved in regulating cortisol metabolism and has important implications for the development of various diseases.
11-beta-Hydroxysteroid dehydrogenases (11β-HSDs) are a group of enzymes that play a crucial role in regulating the levels of active glucocorticoids in the body. These enzymes are found in various tissues, including the liver, adipose tissue, and the brain. There are two main isoforms of 11β-HSD: 11β-HSD1 and 11β-HSD2. 11β-HSD1 converts inactive cortisone to its active form, cortisol, in the liver and adipose tissue. This enzyme is involved in the regulation of glucose metabolism, insulin sensitivity, and inflammation. On the other hand, 11β-HSD2 converts active cortisol to its inactive form, cortisone, in the kidneys and other tissues. This enzyme helps to protect the body from the harmful effects of excess cortisol, such as weight gain, insulin resistance, and high blood pressure. Dysregulation of 11β-HSD activity has been implicated in various diseases, including obesity, diabetes, cardiovascular disease, and depression. Therefore, understanding the role of 11β-HSDs in the body and developing drugs that target these enzymes may have therapeutic potential for the treatment of these diseases.
Hormone antagonists are medications that block or inhibit the effects of hormones in the body. They are often used in medical treatments to counteract the effects of hormones that are either overactive or underactive. Examples of hormone antagonists include: 1. Selective estrogen receptor modulators (SERMs): These medications block the effects of estrogen in some tissues but not others. They are used to treat conditions such as breast cancer and osteoporosis. 2. Progestins: These medications mimic the effects of the hormone progesterone and are used to treat conditions such as menopause symptoms and endometriosis. 3. Androgens: These medications block the effects of testosterone and are used to treat conditions such as prostate cancer and hirsutism (excessive hair growth in women). 4. Gonadotropin-releasing hormone (GnRH) antagonists: These medications block the release of gonadotropins, hormones that stimulate the ovaries and testes to produce sex hormones. They are used to treat conditions such as endometriosis and prostate cancer. Overall, hormone antagonists are an important tool in the medical field for treating a variety of conditions related to hormonal imbalances.
Prednisolone is a synthetic glucocorticoid hormone that is used in the medical field to treat a variety of conditions.

In addition, prednisolone is used to treat certain types of cancer, such as lymphoma and leukemia, and to prevent rejection of transplanted organs. It is available in various forms, including tablets, injections, and eye drops, and is typically prescribed by a doctor or other healthcare professional.
11-beta-Hydroxysteroid Dehydrogenase Type 2 (11β-HSD2) is an enzyme that plays a crucial role in regulating the levels of cortisol, a hormone produced by the adrenal gland. It is primarily found in the liver, kidney, and adipose tissue. The primary function of 11β-HSD2 is to convert cortisol to its inactive form, cortisone. This process helps to prevent cortisol from exerting its effects on various tissues throughout the body, including the brain, muscles, and immune system. In the medical field, 11β-HSD2 is of particular interest because of its role in the development of metabolic disorders such as obesity, insulin resistance, and type 2 diabetes. Studies have shown that individuals with reduced activity of 11β-HSD2 are less likely to develop these conditions, suggesting that the enzyme may play a protective role against metabolic disease. In addition, 11β-HSD2 has been implicated in the development of certain psychiatric disorders, such as depression and anxiety. Research has shown that individuals with reduced activity of 11β-HSD2 may be more susceptible to the effects of stress and may be at increased risk for developing these conditions. Overall, 11β-HSD2 is a critical enzyme that plays a key role in regulating cortisol levels and maintaining metabolic and psychiatric health.
Cortisone is a synthetic form of the hormone cortisol, which is produced by the adrenal glands. It is a corticosteroid medication that is used to treat a variety of inflammatory and autoimmune conditions, such as rheumatoid arthritis, lupus, and psoriasis. Cortisone can also be used to treat allergies, asthma, and other respiratory conditions, as well as to reduce swelling and inflammation in the body. It is available in various forms, including tablets, injections, and creams. Cortisone is a potent medication and should only be used under the guidance of a healthcare professional.
Anti-inflammatory agents are medications that are used to reduce inflammation in the body. Inflammation is a natural response of the immune system to injury or infection, but chronic inflammation can lead to a variety of health problems, including autoimmune diseases, cancer, and cardiovascular disease. Anti-inflammatory agents work by blocking the production of inflammatory molecules, such as prostaglandins and cytokines, which are responsible for causing inflammation. They can also reduce the activity of immune cells that contribute to inflammation. There are several types of anti-inflammatory agents, including nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and biologic agents. NSAIDs, such as aspirin and ibuprofen, are commonly used to relieve pain and reduce inflammation in conditions such as arthritis and headaches. Corticosteroids, such as prednisone, are powerful anti-inflammatory agents that are used to treat a wide range of conditions, including asthma, allergies, and autoimmune diseases. Biologic agents, such as TNF inhibitors, are a newer class of anti-inflammatory agents that are used to treat autoimmune diseases such as rheumatoid arthritis and Crohn's disease. It is important to note that while anti-inflammatory agents can be effective in reducing inflammation, they can also have side effects and may not be appropriate for everyone. It is important to work with a healthcare provider to determine the best treatment plan for your individual needs.
In the medical field, RNA, Messenger (mRNA) refers to a type of RNA molecule that carries genetic information from DNA in the nucleus of a cell to the ribosomes, where proteins are synthesized. During the process of transcription, the DNA sequence of a gene is copied into a complementary RNA sequence called messenger RNA (mRNA). This mRNA molecule then leaves the nucleus and travels to the cytoplasm of the cell, where it binds to ribosomes and serves as a template for the synthesis of a specific protein. The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein that is synthesized. Therefore, changes in the sequence of nucleotides in the mRNA molecule can result in changes in the amino acid sequence of the protein, which can affect the function of the protein and potentially lead to disease. mRNA molecules are often used in medical research and therapy as a way to introduce new genetic information into cells. For example, mRNA vaccines work by introducing a small piece of mRNA that encodes for a specific protein, which triggers an immune response in the body.
Betamethasone is a synthetic glucocorticoid hormone that is used in the medical field as a potent anti-inflammatory and immunosuppressive agent. It is commonly used to treat a variety of conditions, including allergic reactions, skin disorders, respiratory diseases, and autoimmune disorders. Betamethasone is available in various forms, including creams, ointments, injections, and tablets. It works by reducing inflammation and suppressing the immune system, which can help to reduce swelling, redness, and itching, as well as prevent the body from attacking healthy tissues. Betamethasone is generally considered safe and effective when used as directed, but it can cause side effects, including skin thinning, stretch marks, and increased risk of infection. It is important to follow the instructions of a healthcare provider when using betamethasone and to report any side effects that occur.
Triamcinolone is a synthetic corticosteroid medication that is used to treat a variety of medical conditions. It is a powerful anti-inflammatory agent that can help reduce swelling, redness, and itching caused by conditions such as allergies, skin disorders, and autoimmune diseases. Triamcinolone is available in various forms, including creams, ointments, injections, and inhalers. It is typically prescribed for conditions such as eczema, psoriasis, contact dermatitis, and allergic reactions. It can also be used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Triamcinolone works by suppressing the immune system and reducing inflammation in the affected area. It can also help reduce the production of certain chemicals that contribute to inflammation and swelling. While triamcinolone is generally safe and effective when used as directed, it can cause side effects such as skin thinning, stretch marks, and increased risk of infection. It is important to follow your doctor's instructions carefully and to report any side effects to your healthcare provider.
Hydroxysteroid dehydrogenases (HSDs) are a group of enzymes that play a crucial role in the metabolism of steroid hormones in the body. These enzymes catalyze the conversion of one form of a steroid hormone to another by removing or adding a hydroxyl group. There are several types of HSDs, each with a specific function and localization in the body. For example, some HSDs are found in the liver, where they help regulate the levels of sex hormones such as estrogen and testosterone. Other HSDs are found in the brain, where they play a role in the regulation of mood and behavior. HSDs are also involved in the metabolism of other types of hormones, such as cortisol and aldosterone. Dysfunction of HSDs can lead to a variety of medical conditions, including hormonal imbalances, mood disorders, and metabolic disorders.
Methylprednisolone is a synthetic glucocorticoid hormone that is used in the medical field to treat a variety of conditions.

It is important to use this medication only as directed by a healthcare provider and to monitor for any potential side effects.
Receptors, Mineralocorticoid are a type of protein found in cells throughout the body that bind to and respond to hormones called mineralocorticoids. These hormones, which include aldosterone and cortisol, play a key role in regulating the body's electrolyte balance, blood pressure, and blood volume. When mineralocorticoids bind to their receptors, they trigger a series of chemical reactions within the cell that help to regulate these processes. Receptors, Mineralocorticoid are found in a variety of tissues, including the kidneys, adrenal glands, and blood vessels. They are also involved in the regulation of other physiological processes, such as glucose metabolism and immune function.
In the medical field, "Cells, Cultured" refers to cells that have been grown and maintained in a controlled environment outside of their natural biological context, typically in a laboratory setting. This process is known as cell culture and involves the isolation of cells from a tissue or organism, followed by their growth and proliferation in a nutrient-rich medium. Cultured cells can be derived from a variety of sources, including human or animal tissues, and can be used for a wide range of applications in medicine and research. For example, cultured cells can be used to study the behavior and function of specific cell types, to develop new drugs and therapies, and to test the safety and efficacy of medical products. Cultured cells can be grown in various types of containers, such as flasks or Petri dishes, and can be maintained at different temperatures and humidity levels to optimize their growth and survival. The medium used to culture cells typically contains a combination of nutrients, growth factors, and other substances that support cell growth and proliferation. Overall, the use of cultured cells has revolutionized medical research and has led to many important discoveries and advancements in the field of medicine.
Annexin A1 is a protein that is expressed by a variety of cell types, including immune cells, epithelial cells, and endothelial cells. It is a member of the annexin family of proteins, which are characterized by their ability to bind to phospholipids and other molecules in the cell membrane.

Inhibitors of ASL have shown promise in preclinical studies as potential cancer treatments, and are currently being investigated in clinical trials.
DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in living organisms. It is composed of four types of nitrogen-containing molecules called nucleotides, which are arranged in a specific sequence to form the genetic code. In the medical field, DNA is often studied as a tool for understanding and diagnosing genetic disorders. Genetic disorders are caused by changes in the DNA sequence that can affect the function of genes, leading to a variety of health problems. By analyzing DNA, doctors and researchers can identify specific genetic mutations that may be responsible for a particular disorder, and develop targeted treatments or therapies to address the underlying cause of the condition. DNA is also used in forensic science to identify individuals based on their unique genetic fingerprint. This is because each person's DNA sequence is unique, and can be used to distinguish one individual from another. DNA analysis is also used in criminal investigations to help solve crimes by linking DNA evidence to suspects or victims.
Pro-opiomelanocortin (POMC) is a precursor protein that is synthesized in the anterior pituitary gland and the hypothalamus. It is a large protein that is cleaved into several smaller peptides, including α-MSH (melanocyte-stimulating hormone), β-endorphin, and ACTH (adrenocorticotropic hormone). In the medical field, POMC and its cleavage products are important for regulating various physiological processes, including appetite, metabolism, stress response, and immune function. For example, α-MSH is involved in the regulation of skin pigmentation and the body's response to stress, while β-endorphin is a natural painkiller that is involved in the body's response to stress and pain. Abnormalities in the production or function of POMC and its cleavage products can lead to various medical conditions, including obesity, diabetes, and adrenal insufficiency. Therefore, POMC and its cleavage products are the subject of ongoing research in the medical field, with the goal of developing new treatments for these conditions.
Cyclic AMP (cAMP) is a signaling molecule that plays a crucial role in many cellular processes, including metabolism, gene expression, and cell proliferation. It is synthesized from adenosine triphosphate (ATP) by the enzyme adenylyl cyclase, and its levels are regulated by various hormones and neurotransmitters. In the medical field, cAMP is often studied in the context of its role in regulating cellular signaling pathways. For example, cAMP is involved in the regulation of the immune system, where it helps to activate immune cells and promote inflammation. It is also involved in the regulation of the cardiovascular system, where it helps to regulate heart rate and blood pressure. In addition, cAMP is often used as a tool in research to study cellular signaling pathways. For example, it is commonly used to activate or inhibit specific signaling pathways in cells, allowing researchers to study the effects of these pathways on cellular function.
Hormones are chemical messengers produced by glands in the endocrine system that regulate various bodily functions. They are transported through the bloodstream to target cells or organs, where they bind to specific receptors and trigger a response. Hormones play a crucial role in regulating growth and development, metabolism, reproduction, and other essential processes in the body. Examples of hormones include insulin, thyroid hormones, estrogen, testosterone, and cortisol. Imbalances in hormone levels can lead to a range of medical conditions, including diabetes, thyroid disorders, infertility, and mood disorders.
In the medical field, "Animals, Newborn" typically refers to animals that are less than 28 days old. This age range is often used to describe the developmental stage of animals, particularly in the context of research or veterinary medicine. Newborn animals may require specialized care and attention, as they are often more vulnerable to illness and injury than older animals. They may also have unique nutritional and behavioral needs that must be addressed in order to promote their growth and development. In some cases, newborn animals may be used in medical research to study various biological processes, such as development, growth, and disease. However, the use of animals in research is highly regulated, and strict ethical guidelines must be followed to ensure the welfare and safety of the animals involved.
