Dietary restrictions (DR) expand age in various species and also slows the occurrence of age-related diseases. Previous studies of flies and yeast have shown that the Rapamycin (TOR) path is very important for the long Umul phenotype resulting from DR. Tor is a protein kinase that is preserved that regulates growth and metabolism in response to nutrition and growth factors.
While some of the downstream TOR targets have been involved in the permit to regulate, it is still unclear whether the additional target of this path is also modulating age. It has been shown that factor hypoxia-1 (HIF-1) is one of the targets of the Tor line in mammalian cells. HIF-1 is a complex of transcription factors that play a major role in oxygen homeostasis, tumor formation, glucose metabolism, cell survival, and inflammatory response. Here, we describe a new role for HIF-1 in modulating extension for life by Dr. Caenorhabditis elegans. We found that the lack of HIF-1 produced a long life, which overlaps with it by inhibiting RSKS-1 / S6 kinases, the main component of the Tor line.
Using the modified Dr. method based on variations in bacterial food concentrations in gelatin plates, we find that HIF-1 modulates longevity in a way that depends on nutrients. HIF-1 Loss-of-Function Mutant extends age in rich nutritional conditions but fails to show an extension of a lifetime below Dr. Instead, mutations at EGL-9, which increases HIF-1 activity, reduces the extension of age below Dr. This disadvantage is saved by the specific expression of EGL-9 networks in certain neurons and muscles. Age increase by HIF-1 or DR depends on the stress regulator of the endoplasmic (ER) reticulum which requires protein-1 (IRE-1) and is associated with a lower level of stress er stress. Therefore, our results show a network specific role for HIF-1 in extension of age by Dr. Engage Stress Line IRE-1 ER.
The role of T cells, TNF Alpha and IFN Gamma in remembrance of immunity to oral challenges with virulent salmonella in mice vaccinated with direct attenuated aro-salmonella vaccines.
SL3261 Salmonella Typhimurium Aroa strain vaccine directly provides solid protection against oral challenges with malignant salmonella, immunity last long after the vaccine has been cleaned from the network. Balb / c mice were immunized with SL3261 and then experiencing vivo depletion of CD4 + and CD8 + cells experienced a withdrawal of immunity to oral challenges with S. Typhimurium C5 Virulent, with increased mortality and burden of bacteria higher in the reticuloendotel (res) system.
Selective thinning CD4 + cells alone significantly experiencing resistance interference 8 and 14 weeks after vaccination is determined by the estimated number of bacteria in the homogenate organ. The thinning of CD8 + cells only has less effects on immunity when done at 8 weeks than on 14 weeks after immunization. The administration of Gamma Anti-IFN or antibodies of anti-TNF Alpha also experienced a recall of immunity, worsened secondary infection in vaccinated mice.
The challenge of Tius immune that runs out of T cells with salmonella virules causes hepatosplenomegaly with focus lesions that are very beautifully visible, and an increase in the amount and severity of necrotic focus on genitals, lymph nodes. The widespread mononuclear cell infiltrate is present. Histopathology in mice treated with anti-IFN gamma is qualitatively similar to those seen in t-cell mice. Conversely, in the anti-TNF mice treated alpha, splenomegaly is far less than in mice that run out of the cell. No granuloma, no mononuclear infiltration was observed and there was severe necrosis; Lesions look similar or worse than those seen in naive mice. Strangely, IFN Gamma can be detected in serum from both controls and mice that run out of T cells on the 8th day of secondary infections, and at Sera from Alpha-ERA-TNF mice on the 6th day of the infection.
HIF-1 modulates dietary restriction-mediated lifespan extension via IRE-1 in Caenorhabditis elegans.
Safety and antitumor activities from apo2 ligands late recombinant.
TNF and FAS ligand induce apoptosis in tumor cells; However, their severe toxicity towards normal tissue inhibits their application with cancer therapy. APO2 Ligand (APO2L, or Trail) is a related molecule that triggers tumor cell apoptosis. APO2L MRNA is expressed in many networks, indicating that ligands may not be toxic to normal cells. To investigate the therapeutic potential of APO2L, we are produced in the original original soluble-soluble-soluble version of the protein. Some types of normal cells are resistant in vitro for apo2l apoptosis induction.
Injections of intravenous intravenous APO2L in nonhuman primates do not cause toxicity detected against the tissue and organs examined. APO2L provides cytostatic or cytotoxic effects in vitro in 32 of 39 cell lines of large intestines, lungs, breasts, kidneys, brain, and skin cancer. Athymic mouse treatment with APO2L shortly after injection of xenograft tumors greatly reduces the incidence of tumors. APO2L mouse care containing solid tumors induced by tumor cell apoptosis, the development of tumors pressed, and increased survival. APO2L works together synergistically with 5-fluorouracil or CPT-11 chemotherapy drugs, causing substantial tumor regression or complete tumor ablation.

Thus, APO2L can have strong anticancer activities without significant toxicity to normal tissue. About 5% of American women and 12% of men will develop kidney stones at a time in their lives, and prevalence has increased in both sexes. Around 80% of the stone consists of calcium oxalate (CAOX) and calcium phosphate (lid); 10% struvite (magnesium ammonium phosphate produced during infection with bacteria that have an enzyme urease), 9% of uric acid (UA); And the remaining 1% consists of a sistin vein or ammonium acid or diagnosed as a stone associated with drugs.
