The conversion of cholest-5-en-3beta-ol into cholest-7-en-3beta-ol by the echinoderms Asterias rubens and Solaster papposus. (1/11)

1. The echinoderms Asterias rubens and Solaster papposus (Class Asteroidea) metabolize injected [4(-14)C]cholest-5-en-3beta-ol to produce labelled 5alpha-cholestan-3beta-ol and 5alpha-cholest-7-en-3beta-ol. 2. Conversion of 5alpha-[4(-14)C]cholestan-3beta-ol into 5alpha-cholest-7-en-3beta-ol was demonstrated in A. Rubens. 3. Incubations of A. rubens with [4(-14)C]cholest-4-en-3-one resulted in the production of labelled 5alpha-cholestan-3-one, 5alpha-cholestan-3beta-ol and 5alpha-cholest-7-en-3beta-ol. 4. [4(-14)C]Sitosterol was metabolized by A. rubens to give 5alpha-stigmastan-3beta-ol and 5alpha-stigmast-7-en-3beta-ol. 5. The significance of these results in relation to the presence of alpha7 sterols in starfish is discussed.  (+info)

A major ozonation product of cholesterol, 3beta-hydroxy-5-oxo-5,6-secocholestan-6-al, induces apoptosis in H9c2 cardiomyoblasts. (2/11)

Cholesterol, a major neutral lipid component of biological membranes and the lung epithelial lining fluids, is susceptible to oxidation by reactive oxygen and nitrogen species including ozone. The oxidation by ozone in biological environments results in the formation of 3beta-hydroxy-5-oxo-5,6-secocholestan-6-al (cholesterol secoaldehyde or CSeco, major product) along with some other minor products. Recently, CSeco has been implicated in the pathogenesis of atherosclerosis and Alzheimer's disease. In this communication, we report that CSeco induces cytotoxicity in H9c2 cardiomyoblasts with an IC(50) of 8.9+/-1.29 microM (n=6). The observed effect of CSeco at low micromolar concentrations retained several key features of apoptosis, such as changes in nuclear morphology, phosphatidylserine externalization, DNA fragmentation, and caspase 3/7 activity. Treatment of cardiomyocytes with 5 microM CSeco for 24h, for instance, resulted in 30.8+/-3.28% apoptotic and 1.8+/-1.11% of necrotic cells as against DMSO controls that only showed 1.3+/-0.33% of apoptosis and 1.6+/-0.67% of necrosis. In general, the loss of cellular viability paralleled the increased occurrence of apoptotic cells in various CSeco treatments. This study, for the first time, demonstrates the induction of apoptotic cell death in cardiomyocytes by a cholesterol ozonation product, implying a role for ozone in myocardial injury.  (+info)

Cytotoxic effects of secosterols and their derivatives on several cultured cells. (8/11)

The cytotoxic effects of various oxysterols on several culture cells were examined. Ozonolysis products of cholesterol, secosterols (3beta-hydroxy-5-oxo-5,6-secocholestan-6-al) and its aldolization product (3beta-hydroxy-5beta-hydroxy-B-norcholestane-6beta-carboxaldehyde) and their keto alcohol and acid derivatives, were found to have potent cytotoxic activities, as compared with major endogenous oxysterols such as 5beta,6beta-epoxycholesterol, 7beta-hydroxycholesterol, 7-ketocholesterol, and 25-hydroxycholesterol. Secosterols might play important roles in tissue damage and inflammation-associated diseases.  (+info)

IGF-1 is a peptide roughly the same structure and size as insulin, or about 70 amino acids long. It belongs to the peptide family of substances identified as growth factors. It is a highly anabolic hormone released in the liver as well as in peripheral tissues such as skeletal muscle. In the body, IGF-1 is released in response to the presence of Human Growth Hormone (HGH). After intense resistance training, the body experiences a surge in GH and IGF, and this is one way that new muscle is built. Although GH is considered to be highly anabolic, in actuality, IGF-1 is suspected to be responsible for the primary anabolic activities of GH ...

Background: Doxorubicin (DOX), a widely used anticancer drug, has been associated with cardiotoxicity. Recently, DOX-induced cardiotoxicity has been attributed to topoisomerase II (TOPII)-β expression and activity. In our study, we investigated the effect of inhibiting TOPII in attenuating the DOX induced cardiotoxicity. Method: H9c2 cardiomyoblasts were treated with 1 or 2 µM DOX (+/-) 1 µM ETO. Cardiotoxicity was assessed by examining cell viability using the MTT assay, hypertrophy of crystal violet stained cardiomyoblasts and ROS production. Results: DOX induced a dose dependent increase in cardiotoxicity as indicated by the significant reduction in cell viability (71.77 ± 9.25% 2 µM DOX vs. 100% control, P,0.05), ROS production and hypertrophy. Stimulation of H9c2 cardiomyoblasts with both 2 µM DOX and 1µM ETO did not show a significant difference in cell viability, ROS production or hypertrophy. Conclusion: DOX induced cardiotoxicity in H9c2 cardiomyoblasts was not exacerbated in the ...
During normal lifespan, the mammalian heart undergoes limited renewal of cardiomyocytes. While the exact mechanism for this renewal remains unclear, two possibilities have been proposed: differentiated myocyte replication and progenitor/immature cell differentiation. This study aimed to characterize a population of cardiomyocyte precursors in the neonatal heart and to determine their ... read more requirement for cardiac development. By tracking the expression of an embryonic Nkx2.5 cardiac enhancer, we identified cardiomyoblasts capable of differentiation into striated cardiomyocytes in vitro. Genome-wide expression profile of neonatal Nkx2.5+ cardiomyoblasts showed the absence of sarcomeric gene and the presence of cardiac transcription factors. To determine the lineage contribution of the Nkx2.5+ cardiomyoblasts, we generated a doxycycline suppressible Cre transgenic mouse under the regulation of the Nkx2.5 enhancer and showed that neonatal Nkx2.5+ cardiomyoblasts mature into cardiomyocytes ...
During the ozonation of tetracycline (TC) in aqueous media at pHs 2.2 and 7.0, the effects of pH variations, protonation and dissociation of functional groups and variation in free radical exposure were investigated to elucidate the transformation pathway. Liquid chromatography-triple quadrupole mass spectrometry detected around 15 ozonation products, and uncovered their production and subsequent degradation patterns. During ozonation at pH 2.2, the TC degradation pathway was proposed on the basis of the structure, ozonation chemistry and mass spectrometry data of TC. Ozonation of TC at the C11a-C12 and C2-C3 double bonds, aromatic ring and amino group generated products of m/z 461, 477, 509 and 416, respectively. Further ozonation at the above mentioned sites gave products of m/z 432, 480, 448, 525 and 496. The removal of TOC reached a maximum of approximate to 40% after 2 h of ozonation, while TC was completely removed within 4-6 min at both pHs. The low TOC removal efficiency might be due to ...

Overall, SARMs do not affect sex drive or sperm count.. As one of the distasteful side effects of steroids or other strong testosterone-enhancers, the negative effects of reduced sex drive and sperm count were on the top of the list when making SARMs. The producers of SARMs wanted to design a supplement that gave all the great benefits of steroids, while still specifically promoting full anabolic activity muscle and bone.. All this is to say that SARMs have been specifically designed to avoid those side effects of reduced sperm count or other sexual side effects with could lead to problems infertility. Plus, they are showing to have minimal effects on the prostate in general, which cant be said for most other steroids or prohormones. By avoiding high concentrations of anabolic steroids, scientists think SARMs will more effectively dodge the risk of throwing hormones wildly off balance.. In fact, SARMs are giving some surprising results during testing phases that look promising. Some SARMs, such ...

Another major signal regulating TORC1 activity is the abundance of amino acids which tells the organism to undergo anabolic activity (1, 22). Conversely the absence of adequate amino acids is a stress which leads to the shutting down of biosynthetic pathways and the induction of autophagy. The major amino acids sensed are the branched chain amino acids, especially leucine, as well as arginine and glutamine. Amino acid sensing involves recruitment of TORC1 from cytoplasm to lysosomes where it interacts with proteins including the Rag GTPases (23), a protein complex termed the ragulator (33), amino acid transporters (17) and the lysosomal vacuolar ATPase (12). In the presence of amino acids, Rheb which is also localized on the lysosome, is activated and in turn activates TORC1. Furthermore, amino acids are necessary for almost all other mechanisms activating TORC1. Low oxygen or low glucose levels prevent TORC1 signaling through AMP Kinase and reduce the activity of the proteins REDD and BMIP3 ...

In this study, the response of pollens obtained from inflorescences of table grape cultivars Italia and Cardinal to different plant growth regulators added to the medium in Petri dishes was evaluated. Statistical analysis showed that pollen germination of cv. Italia was not influenced (p≥0.05) by the plant growth regulators (Table 1). Pollens not treated with any plant growth regulators (control) showed 26.08% germination, while the highest ratio was obtained from 0.001 mg L-1 EBR treatment (44.40%). The lowest percentage of germination was obtained from the application of 0.1 mg L-1 HBR (17.85%). Although no significant differences were observed, it was seen in the mean values of the applications that as the amount of GA3 in the combination treatments increased, the mean ratio of pollen germination slightly decreased. In addition, homobrassinolide yielded higher germination compared to epibrassinolide. Pollens of cv. Cardinal, on the other hand, responded significantly (p≤0.01) ...

Resveratrol exhibits anti-tumor properties against different types of cancer. In this study, several polyhydroxylated resveratrol derivatives were prepared with the aim of discovering new leading compounds with clinical potential for human colon cancer chemotherapy. Among these compounds, 3,3,4,5,5-pentahydroxy-. trans-stilbene (PHS) displayed the most potent cytotoxicity and triggered apoptosis in HT-29 cells as evidenced by increased poly(ADP-ribose) polymerase (PARP) cleavage, elevated levels of cytoplasmic nucleosomes and DNA fragmentation. Further mechanistic analysis revealed that PHS-induced apoptosis was caspase-dependent and mediated by its pro-oxidative action through up-regulation of reactive oxidative species generation and depletion of intracellular glutathione. © 2010 Elsevier B.V ...

The central role of cyclin-dependent kinases (CDKs) in cell cycle regulation makes them a promising target for studying inhibitory molecules that can modify the degree of cell proliferation. The discovery of specific inhibitors of CDKs such as polyhydroxylated flavones has opened the way to investigation and design of antimitotic compounds. A novel flavone, (-)-cis-5,7-dihydroxyphenyl-8-[4-(3-hydroxy-1-methyl)piperidinyl] -4H-1-benzopyran-4-one hydrochloride hemihydrate (L868276), is a potent inhibitor of CDKs. A chlorinated form, flavopiridol, is currently in phase I clinical trials as a drug against breast tumors. We determined the crystal structure of a complex between CDK2 and L868276 at 2.33 angstroms resolution and refined to an Rfactor 20.3%. The aromatic portion of the inhibitor binds to the adenine-binding pocket of CDK2, and the position of the phenyl group of the inhibitor enables the inhibitor to make contacts with the enzyme not observed in the ATP complex structure. The analysis of ...

Once administered, serum concentrations of this hormone will rise for several days, and remain markedly elevated for approximately two weeks. For medical purposes this is the most widely prescribed testosterone used regularly to treat cases of hypogonadism and other disorders related to androgen deficiency. As with all testosterone products it has a strong anabolic activity, with a pronounced androgenic component. Thus it can provide significant gains in strength and muscle mass, as well a noticeable increase in libido. An added benefit, with all testosterone products is the relief of tendon pain, faster recuperation and an increase in the level and duration of physical output due to the oxygen rich blood along with an increase of red blood cells. Although when taken at reasonable dosages aromatisation should not be a problem, some patients ...
The polyhydroxylated derivatives of 7-dehydro, 6-ketocholesterol (Ecdysone, Ecdysteroids, Ecd) were accidentally discovered in the search for an insect moulting hormone in 1965. The first Ecd compound, named ecdysone (ecdysis = shedding off the cuticle), was isolated from silkworm pupae.

In the oceans, naturally occurring manganese (Mn) is released from the sediments during events of hypoxia. While neuro- and immuno-toxic effects of bioavailable manganese are well documented for crustaceans, studies of similar effects of manganese on other marine invertebrates are comparatively few. Here, we developed a new functional test "the repeated turning assay" to investigate if manganese exposure at ∼12 mg L−1 affected motoric behaviour of two asteroid echinoderms, the Common sea star, Asterias rubens, and the Black brittle star, Ophiocomina nigra. By measuring of the turning-over capacity, from dorsal to ventral position, after one and two weeks of manganese exposure, we showed that for both species Mn exposure significantly delayed the ability to turn. After a recovery period of two weeks, the capacity of turning-over was not restored to that of unexposed animals neither for A. rubens nor for O. nigra. Further investigation of sea stars showed that Mn accumulated ∼5 fold in the ...
A method of manufacturing a polyolefin using a catalyst system of an ingredient (A) and ingredient (B), with ingredient A being obtained through successive reaction steps. Ingredient A is prepared by forming a mixture of (1) the combination of (a) metallic magnesium or an oxygen-containing organic compound of magnesium with (b) a mixture of a monohydroxylated organic compound and a polyhydroxylated organic compound, (2) oxygen-containing organic compounds of titanium and (3) at least one alpha-olefin having at least 4 carbon atoms, such as 1-hexene. The resulting solution is reacted in sequence with (4) at least one first halogenated aluminum compound, (5) at least one silicon compound and (6) at least one second halogenated aluminum compound. Ingredient B is an organometallic compound of metals from Group Ia, IIa, IIIa or IVa of the Periodic Table. The resulting free-flowing polyolefin is characterized by a large average particle size and small amount of fine particles.
Acne on the face, neck and shoulders. We frequently find acne in Epileptics who have been maltreated by bromides. This remedy is especially adapted to the acne simplex and the acne indurata, especially in hyperaesthetic, nervous females. Face flushed. Acne of face, pustules. General failure of mental power, loss of memory, melancholia, anesthesia of the mucous membranes. Suicidal mania with tremulousness. Itching of skin worse on chest, shoulders, and face. Anesthesia of skin. This remedy may be given if Asterias Rubens fails. Dr. J.H.Clarke says, "I know of no remedy of such universal usefulness in cases of simple acne as Kali bromatum 30," and the late Dr.A.M. Cushing recommended Arsenicum bromatum 4x as very efficacious.Thuja is one of our best remedies for acne facialis. Calcarea picrata is also a useful remedy for acne; clinically it has been found one of the good remedies. Calcarea sulphurica is indicated where the pimples suppurate ...

Chelated enolates are versatile nucleophiles for palladium-catalysed allylic alkylations. Even with complex allylic substrates the reaction proceed without significant isomerisation. This allows the stereoselective introduction of polyhydroxylated allylic sidechains into amino acids and peptides with retention of the olefin geometry ...
