The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.

Applicability of 99mTc-HL91, a putative hypoxic tracer, to detection of tumor hypoxia. (1/243)

To elucidate the applicability of 99mTc-HL91 (HL91) a putative hypoxic tracer, to the imaging of hypoxia in tumors, a biodistribution study of the tracer was performed. The intratumoral distribution of HL91 was compared with that of 14C-deoxyglucose (DG) and the expression of glucose transporter 1 (GLUT1) in an implanted tumor. METHODS: Biodistribution of HL91 after intravenous injection into Wistar rats with rat mammary tumor (Walker-256) was studied by determining blood and tissue levels of radioactivity from 15 min to 6 h after injection. Dual ex vivo autoradiography was performed on sections of the tumor using HL91 (74 MBq) and DG (185 kBq). The same sections were immunohistologically analyzed with anti-GLUT1 antibody. Tumor tissue was histologically divided into areas of viable cancer cells, necrosis and granulation tissue. The viable cancer cell area was further divided into normoxic and hypoxic areas. Uptake of both tracers in each area was measured quantitatively. The intensity of GLUT1 staining (relative optical density [ROD]) in each area was evaluated by densitometry. RESULTS: The uptake of HL91 in the tumor reached a maximal value (0.897 +/- 0.118% ID [injected dose], mean +/- SD, n = 5) at 120 min after intravenous injection of HL91, then gradually decreased. The tumor-to-muscle ratio continued to increase until 360 min (4.34 at 120 min, 7.01 at 240 min and 10.4 at 360 min). HL91 accumulated to significantly higher levels in the hypoxic area than those in the other tissues (P < 0.0001). Uptake of DG and expression of GLUT1 were significantly higher in the hypoxic area than in the normoxic area (P < 0.0001). In the viable cancer cell area, uptake of HL91 and expression of GLUT1 were strongly correlated (r = 0.624-0.868, mean r = 0.743, P < 0.0001), and DG uptake was moderately correlated with GLUT1 expression (r = 0.328-0.669, mean r = 0.505, P < 0.0001). CONCLUSION: These results indicate that HL91 can be used to detect tumor hypoxia.  (+info)

Postmenopause-like bone loss by mammary carcinoma Walker256/S which secretes luteinizing hormone-releasing hormone. (2/243)

When Walker 256/S carcinosarcoma (W256/S) was subcutaneously inoculated into the back of mature female Wistar Imamichi rats (10-week-old), the tumor grew rapidly and caused increases in the urinary excretions of calcium and hydroxyproline, without changes in the serum concentrations of calcium and inorganic phosphorus. Furthermore, osteoporosis-like changes in the femurs and decrease in uterus weight were observed, as previously reported for W256/S-bearing young rats. In the healthy mature female rats, the estrus cycle passed through four stages (proestrus, estrus, metestrus and diestrus) within 4 to 5 days, with a peak of serum estradiol and progesterone levels in the proestrus stage. On the other hand, after subcutaneous inoculation of W256/S into the rats, the estrus cycle tended to pause upon the metestrus or diestrus stage, accompanied with significantly low estradiol and progesterone levels in serum. W256/S tumor produced and secreted luteinizing hormone-releasing hormone (LH-RH). In conclusion, it seems that the ectopical secretion of LH-RH from the tumor resulted in the decrease in the secretion of gonadotropic hormones, following low level of sex hormones and stopping the estrus cycle. Therefore, W256/S-bearing rats may be a model for osteoporosis of hypoovarianism or postmenopause.  (+info)

Tissue distribution of rat macroglobulins in tumour-bearing rats. (3/243)

Rat macroglobulins were determined in blood sera and extracts of tissues of intact rats and rats with Walker carcinoma by rocket immunoelectrophoresis. The serum levels of alpha1-macroglobulin (alpha1MG) alpha2-macroglobulin (alpha2MG) and pregnancy-associated alpha1-glycoprotein (alpha1PAG) were 1.86 +/- 0.07 mg/ml, 0.12 +/- 0. 02 mg/ml and 18.32 +/- 4.07 AU/ml respectively in control rats. Maximum concentrations of alpha1MG were found in heart, lung and spleen and lesser quantities were in liver and thymus, while alpha2MG and alpha1PAG were not found at all in tissue extracts from control rats. Serum alpha2MG and alpha1PAG concentrations increased more than 30-fold in tumour-bearing rats compared to control animals, while alpha1MG serum concentration was little changed. Increases in all three macroglobulins occurred in the tissues of tumour-bearing rats, particularly alpha1PAG. The tissue concentrations of alpha1MG and alpha2MG were similar and the tissue distribution was also similar with highest concentrations in heart and lung. Considerable quantities of the proteins were found in the tumour and part of peritoneum which made contact with the tumour. Changes in the protein concentrations in serum and tissue extracts of tumour-bearing rats suggest that all members of rat macroglobulin family are disturbed during the development of the Walker carcinoma, though only alpha2MG and alpha1PAG were substantially elevated.  (+info)

Treatment with ibandronate preserves bone in experimental tumour-induced bone loss. (4/243)

Cancer-induced bone diseases are often associated with increased bone resorption and pathological fractures. In recent years, osteoprotective agents such as bisphosphonates have been studied extensively and have been shown to inhibit cancer-related bone resorption in experimental and clinical studies. The third-generation bisphosphonate, ibandronate (BM 21.0955), is a potent compound for controlling tumour osteolysis and hypercalcaemia in rats bearing Walker 256 carcinosarcoma. We have studied the effect of ibandronate given as an interventional treatment on bone strength and bone loss after the onset of tumour growth in bone. Our results suggest that it is capable of preserving bone quality in rats bearing Walker 256 carcinosarcoma cells. Since other bisphosphonates have produced comparable results in man after their success in the Walker 256 animal models our findings suggest that ibandronate may be a powerful treatment for maintaining skeletal integrity in patients with metastatic bone disease.  (+info)

The hemolytic component of cancer anemia: effects of osmotic and metabolic stress on the erythrocytes of rats bearing multifocal inoculations of the Walker 256 tumor. (5/243)

Cancer anemia is classified as an anemia of chronic diseases, although it is sometimes the first symptom of cancer. Cancer anemia includes a hemolytic component, important in the terminal stage when even transfused cells are rapidly destroyed. The presence of a chronic component and the terminal complications of the illness limit studies of the hemolytic component. A multifocal model of tumor growth was used here to simulate the terminal metastatic dissemination stage (several simultaneous inoculations of Walker 256 cells). The hemolytic component of anemia began 3-4 days after inoculation in 100% of the rats and progressed rapidly thereafter: Hb levels dropped from 14.9 +/- 0.02 to 8.7 +/- 0.06 from days 7 to 11 ( approximately 5 times the physiologically normal rate in rats) in the absence of bleeding. The development of anemia was correlated (r2 = 0.86) with the development of other systemic effects such as anorexia. There was a significant decrease in the osmotic fragility of circulating erythrocytes: the NaCl concentration causing 50% lysis was reduced from 4.52 +/- 0.06 to 4.10 +/- 0.01 (P<0.01) on day 7, indicating a reduction in erythrocyte volume. However, with mild metabolic stress (4-h incubation at 37oC), the erythrocytes showed a greater increase in osmotic fragility than the controls, suggesting marked alteration of erythrocyte homeostasis. These effects may be due to primary plasma membrane alterations (transport and/or permeability) and/or may be secondary to metabolic changes. This multifocal model is adequate for studying the hemolytic component of cancer anemia since it is rapid, highly reproducible and causes minimal animal suffering.  (+info)

Vascularization of normal and neoplastic tissues grafted to the chick chorioallantois. Role of host and preexisting graft blood vessels. (6/243)

Adult, embryonic, and tumor tissues were grafted to the chorioallantoic membrane of the chick embryo to determine whether blood vessels originally within implants were reused in the establishment of a new blood supply. Grafts were examined daily by in vivo stereomicroscopy and in histologic sections. Colloidal carbon injections into the host vasculature served to confirm the precise onset of graft circulation; Preexisting tumor blood vessels disintegrated by 24 hours after implantation and revascularization occurred at 3 days by penetration of proliferating host vessels into the tumor tissue. Adult tissues did not revascularize, and the original graft vasculature progressively disintegrated during the 9 days of observation, Most embryonic tissues revascularized in 1 or 2 days by reperfusion of the existing graft vasculature. Anastomosis of host and graft blood vessels seemed to result from connections between newly formed vascular sprouts arising from both vasculatures. This study indicates that only tumor grafts acquire their blood supply solely by formation of new blood vessels from the host microvasculature. By contrast revascularization of normal tissues, when it does occur, is predominately the result of perfusion of the preexisting graft blood vessels.  (+info)

Apparent cellular ingress of albumin in Walker 256 tumor and rat muscle. (7/243)

Tissue albumin distribution was measured in Walker 256 tumor and skeletal muscle in vivo in 36 rats. Vascular, extravascular-extracellular, and total tissue water spaces were determined for each tissue sample by isotopic techniques. Tissue interstitial and lymph albumin values were calculated from thoracic duct albumin concentrations, and vascular albumin was determined from serum albumin levels. Total tissue albumin was measured by dilution. These data demonstrate a third tissue albumin pool that equilibrates in 3 days compared to the rapid equilibration (2 hr) of vascular and extracellular-extravascular spaces. The pool is present in both muscle and tumor but appears to equilibrate more rapidly in tumor tissue. This finding suggests that cellular ingress of albumin occurs in vivo, which may explain increased albumin catabolism in tumor-bearing hosts.  (+info)

Tissue water content and nuclear magnetic resonance in normal and tumor tissues. (8/243)

Pulsed proton nuclear magnetic resonance was used to differentiate between normal and malignant tissues. When the tissue water content varied from 80 to 93%, the tumors exhibited spin-lattice relaxation times (T1) from 0.9 to 1.8 sec. We report also the results obtained on 9-day-old embryos and on liver, brain, and heart from 2-day-old rats. A good correlation between the spin-lattice (T1) and spin-spin (T2) relaxation times and the tissue water content was found for all tissues studied. The relaxation times T1 and T2 and water content in Walker 256 carcinoma and its lymph node metastasis were quite similar.  (+info)

The relationship between tumor physiology and the pharmacokinetics of 2,2 difluorodeoxycytidine [gemcitabine (dFdC)] in ex vivo perfused human small cell lung cancer was examined. Two small cell lung cancer sublines, 54A and 54B, with known in vivo sensitivity to dFdC, were grown as tissue-isolated tumors in athymic mice and perfused ex vivo with or without 20-40 micrometer dFdC. Arteriovenous differences in gases, pH, and metabolites were determined before and during drug infusion. The geometric flow resistance (FR) of individual tumors was calculated, and dFdC and its inactive metabolite 2,2 difluorodeoxyuridine were determined by high-performance liquid chromatography of consecutive samples from the output line. Both tumors had prominent lactate production concurrent with a significant O2 consumption. The arteriovenous pH drop was approximately 0.3 in both tumor lines. Significant metabolic differences between 54A and 54B tumors were found that elucidated previously described differences ...

Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer, and is ranked the sixth most common neoplasm and the third leading cause of cancer-related deaths. Photothermal therapy (PTT) for thermal ablation of local tumors has recently emerged as a therapeutic strategy. However, the relatively high temperature of over 50°C may lead to unexpected heat-related damage to tumor-adjacent normal tissues. Herein, we designed and synthesized ataxia telangiectasia mutated (ATM) inhibitor loaded hollow-structured CuS NPs with surface modification with anti-TGF-ß antibody ([email protected]ß NPs). [email protected]ß NPs are highly photo-stable, can release encapsulated drugs, and increase the temperature to an effective level in a near-infrared (NIR)-responsive manner. Moreover, [email protected]ß NPs specifically target tumors and thereby significantly inhibit tumor growth on contribution to synergistic low-temperature PTT and chemotherapy. This system not only achieved low-temperature PTT ...

Treatment of the 1-day-old Ehrlich ascites tumor with combinations of selected doses of l-asparaginase and the l-glutamine antagonist, 6-diazo-5-oxo-l-norleucine, or of the l-glutamine acid antagonist, dl-methionine-dl-sulfoximine, produced significantly more growth inhibition without a marked increase in host toxicity than did treatment with l-asparaginase administered alone. In the 3-day-old tumor treated with the combination of l-asparaginase and 6-diazo-5-oxo-l-norleucine, there was a significant enhancement of growth inhibition as compared with the effect of either drug used alone. A less significant increase of growth inhibition was obtained with combination of l-asparaginase and l-glutamyl-γ-hydrazide as compared with the effect of this chemical administered alone.. Combinations of l-asparaginase and 6-diazo-5-oxo-l-norleucine produced increased antitumor effects in mouse melanoma B16 and to a lesser degree in the solid form of Ehrlich tumor and Walker carcinosarcoma 256 of the ...
The effect of Walker tumor on sulphacetamide distribution was studied in rats 21 days after tumor implantation in a hind leg. After oral administration of sulphacetamide (5 and 20 min), the concentration of the drug was found to be lower in the plasma and liver of tumor-bearing rats when compared with that of control group. However, 90 min after sulphacetamide administration, the concentration of the drug in these same tissues was found to be higher in tumor-bearing rats than in control animals. Whereas the tumor had no apparent effect on sulphacetamide concentration in the brain, drug concentrations in the fat tissue of tumor-bearing rats were constantly higher than those of control animals. These changes in sulphacetamide disposition kinetics could be explained in part by delay in gastrointestinal absorption of the drug. Contrary to what was observed after oral administration, constantly higher drug concentrations were found in the plasma of tumor-bearing rats after iv injection of ...
During starvation for 72 h, tumour-bearing rats showed accelerated ketonaemia and marked ketonuria. Total blood [ketone bodies] were 8.53 mM and 3.34 mM in tumour-bearing and control (non-tumour-bearing) rats respectively (P less than 0.001). The [3-hydroxybutyrate]/[acetoacetate] ratio was 1.3 in the tumour-bearing rats, compared with 3.2 in the controls at 72 h (P less than 0.001). Blood [glucose] and hepatic [glycogen] were lower at the start of starvation in tumour-bearing rats, whereas plasma [non-esterified fatty acids] were not increased above those in the control rats during starvation. After functional hepatectomy, blood [acetoacetate], but not [3-hydroxybutyrate], decreased rapidly in tumour-bearing rats, whereas both ketone bodies decreased, and at a slower rate, in the control rats. Blood [glucose] decreased more rapidly in the hepatectomized control rats. Hepatocytes prepared from 72 h-starved tumour-bearing and control rats showed similar rates of ketogenesis from palmitate, and ...
Recently, we demonstrated that verapamil, an L-type Ca2+ channel blocker, inhibits the activation of splenic lymphocytes during Walker 256 ascitic tumor development in adult rats. In the present study we have analyzed the changes in spleen size, splenic lymphocyte proliferation, white pulp organization and relative size as well as food intake, and levels of blood haemoglobin in Walker 256 tumor bearing rats. These rats displayed a spleen enlargement associated with a significant increase in white pulp area and TCD8(+) lymphocyte proliferation. Levels of interferon-gamma, but not of interleukin-10, were elevated in tumor bearing rats, indicating a Th1-type immune response. These manifestations were accompanied by reduced food intake and anaemia. Treatment of tumor bearing rats with verapamil avoided spleen enlargement and increased expression of cytokines, as well as the splenic TCD8(+) lymphocyte proliferation. In addition, verapamil treatment promoted an exacerbation of the anorexia, and ...
Tetraspanins function as molecular organizers of multi-protein complexes by assembling primary complexes of a relatively low mass into extensive networks involved in cellular signalling. In this paper, we summarize our studies performed on the tetraspanin D6.1A/CO-029/TM4SF3 expressed by rat carcinoma cells. Primary complexes of D6.1A are almost indistinguishable from complexes isolated with anti-CD9 antibody. Indeed, both tetraspanins directly associate with each other and with a third tetraspanin, CD81. Moreover, FPRP (prostaglandin F2α receptor-regulatory protein)/EWI-F/CD9P-1), an Ig superfamily member that has been described to interact with CD9 and CD81, is also a prominent element in D6.1A complexes. Primary complexes isolated with D6.1A-specific antibody are clearly different from complexes containing the tetraspanin CD151. CD151 is found to interact only with D6.1A if milder conditions, i.e. lysis with LubrolWX instead of Brij96, are applied to disrupt cellular membranes. CD151 ...

During February 1963, Walker joined Billy Hargis in an anti-communist tour named Operation Midnight Ride.[25] In a speech Walker made on March 5, reported in the Dallas Times Herald, he called on the United States military to liquidate the [communist] scourge that has descended upon the island of Cuba.[26] Seven days later, Lee Harvey Oswald ordered by mail a Carcano rifle, using the alias A. Hidell.[27] According to the Warren Commission, Oswald began to put Walker under surveillance, photographing the generals Dallas home on the weekend of March 9-10.[28] Oswalds friend, 51-year-old Russian émigré and petroleum geologist George de Mohrenschildt,[29] would later tell the Warren Commission that he knew that Oswald disliked General Walker.[30] On April 10, 1963, as Walker was sitting at a desk in his dining room, a bullet struck the wooden frame of his dining room window. Walker was injured in the forearm by fragments. Marina Oswald later testified that her husband told her that he ...
Carcinosarcomas are rare tumours, which have both epithelial, and connective tissue elements. They are most commonly seen in the female genital tract. Rarely they arise from the gastrointestinal tract. We report a case of Carcinosarcoma arising as a primary in the spleen of a male aged 60yrs. The most unique feature of this tumour is the presence of osteosarcomatous element. This report highlights the importance of clinical awareness of such rare tumours and gives a brief overview on presentation, probable aetiology, diagnosis and management with literature review of carcinosarcoma ...
Sarcomatoid carcinoma, or carcinosarcoma, is a neoplasm that contains both sarcomatous and carcinomatous elements. It is an extremely rare cancer most often arising from visceral organs. Here we report the seventh documented de novo case of carcinosarcoma of the bone, in a young female who showed initial clinical improvement with gemcitabine and docetaxel. A 36-year-old Caucasian female presented with diffuse musculoskeletal pain that had progressed from her shoulder to her back, arm, and knee over 6 months. Imaging revealed diffuse sclerotic lesions of bilateral humeral heads, iliac and ischial bones, and thoracic and lumbar spine. Histopathologic examination of biopsies from the T9 vertebra and left femur showed mainly sarcomatous spindle cells with focal osteoid production. Immunostaining showed the cells to be OSCAR cytokeratin, patchy positive for pankeratin, and negative for CK7, GATA3, S100, SOX10, CD99, EMA, AE1/AE3, and HMW keratin indicative of an epithelial origin.

The sequence GXXXXGKT/S, popularly known as Walker motif A, is widely believed to be the site for binding nucleotides in many proteins. Examination of the crystal structures in the Protein Data Bank showed that about half of the examples having these sequences do not bind or use nucleotides. Data analyses showed 92 different Walker sequences of the variable quartet (XXXX). Ramachandran angles in this segment revealed conformational similarity in the group of 45 proteins, known to bind or utilize nucleotides. The conformations of this segment in other proteins differ widely and it is not known whether they play any role in their functions. A flip of a peptide unit at different locations, with little change in the backbone conformation was noted in nine pairs of these proteins having same Walker sequence. An examination of the immediate neighborhood of the Walker sequence indicates that this region is preceded by a $\beta$-strand and followed by an $\alpha$-helix, resulting in the motif ...

Forearm rests are combined with a conventional invalid walker. The forearm rests are located generally spaced above the normal hand-grips. The forearm rests are advantageous for providing inward lateral support to the users outwardly flexed forearms while the user is grasping the hand-grips and while the user is one of (i) maneuvering the walker and (ii) partly supporting and stabilizing him or herself while standing and walking. The forearm rests provide better stability and support for a user who has diminished arm strength and/or diminished motor control over his or her arm muscles. The forearm-rests can be formed in an accessory apparatus that allows attachment to a conventional walker (without forearm rests) in order to enhance the walker and give it the desirable forearm rests.

OK, Im stretching journalistic licence somewhat with that headline but the fact of the matter is that a joint Italian-American study reveals even small amounts of Pecorino Romano protect against arteriosclerosis and contain anti-inflammatory and cancer-fighting properties.. The Universities of Sassari and Cagliari (Sardinia, Italy) in conjunction with a team of doctors from the United States, announced this week the results of a six-year long research study confirming that Pecorino or sheeps-milk cheese contains high amounts of CLA (Conjugated Linoleic Acid), an Omega-6 polyunsaturated fatty acid naturally found in certain food groups and which shows bioactive properties for humans.. The study, conducted in Sardinia from 2003 to 2009 confirms the health benefits of CLA, including reducing fat, suppressing diabetes, preserving muscle tissue and inhibiting tumor growths on the skin, mammary glands and stomach.. Wow! Almost makes me rush out and buy the stuff.. CLA is found primarily in milk ...

Central Institute of Medicinal and Aromatic Plants (CIMAP) at Lucknow is working on the functional genomics research for highly important plants like anticancer plant, anti-malarial plant, pain therapeutics yielding plant, revitalizing immuno-modulator plant, traditionally most valued aromatic-cum-medicinal plant and the mint yielding aromatic plant, the plant which has also created history to place India on the top position ...

Walker remained blissfully unaware of the extent of the damage when he returned home following the fixture, with the devastating news only emerging following a scan over the weekend.. Walker, who only returned to his boyhood club from Wigan over the summer, will now face around three months on the sidelines - just as he was beginning to rediscover his form and fitness in maroon once more.. He said: I was really gutted. I had played a few 90 minutes in a row and felt like I was starting to get my fitness back, I had scored a couple of goals. But theres nothing I can do about it now.. There are great medical staff here and hopefully they can get me back fit as quickly as possible.. I was just tracking back and the Motherwell player, [Liam] Donnelly, went to have a strike and I managed to nick the ball away in front of him. He has followed through on the back of my ankle.. I didnt think it was that bad at the time. However, the scans have shown that Ive fractured my fibula. The game was ...

First of all, Id like to apologise to Owen Walker for so shamefully ignoring his comments on my last article. I realise I should have taken a day off work to stand watch over the article so I could respond to his comments immediately. Had I realised that my having a life outside of responding to his comments would affect his opinion of me, I would naturally have dropped everything else to devote my whole, undivided attention to somehow unravelling the conundrum he dropped in my lap. Sadly I didnt know, and since its of such vital importance to him to get a response, I shall make up for my earlier faux pas by devoting an entire article to him. He actually raised an interesting point that would have taken more space than a reply to make, so this isnt purely a display of sarcasm on my part. What can I say? Sometimes the inner childs sense of humour will not be denied. Ill quote Owen Walker in italics. Hmmm... a theory is formed over time.. Im not sure what you mean by formed. Do you mean ...
