Scientists discover mechanism of thalidomide

(Technical University of Munich (TUM)) In the 1950s, thalidomide (Contergan) was prescribed as a sedative drug to pregnant women, resulting in a great number of infants with serious malformations. Up to now, the reasons for these disastrous birth defects have remained unclear. Researchers at the Technical University of Munich have at last identified the molecular mechanism of thalidomide. Their findings are highly relevant to current cancer therapies, as related substances are essential components of modern cancer treatment regimens.

This study highlights how the use of in vitro 3D model can allow rapid screening and selection of new and safer drugs. Introduction Angiogenesis is a complex and finely regulated process that consists of the growth of new capillary blood vessels from pre-existing vessels to create communication pathways among tissues. The coordination of different activities such as endothelial cell proliferation and migration, metalloproteinase function, integrin expression and pericyte stabilization is essential for angiogenesis (Folkman, 1984). The “angiogenic switch” is “on” when the balance between pro-...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...

Conclusions: These finding suggest that Poly-ICLC could be safely used for inducing transient innate immune responses in treated HIV+ subjects indicating promise as an adjuvant for HIV therapeutic vaccines. Trial Registration: www.ClinicalTrials.gov, identifier: NCT02071095. Introduction Innate immune dysregulation during HIV infection hinders the formation of anti-HIV adaptive immunity (1–6) resulting in rampant viral dissemination and progression to AIDS. Adherence to combination anti-retroviral therapy (cART) regimens controls viremia, restores CD4+T cell counts and reverses immune dysfunction to a larg ext...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

Abstract Reducing the adverse effects of chemotherapy on normal cells such as endothelial cells is a determinant factor of treatment success especially in pregnant women. In this regard, modulatory effect of L-arginine on various cancers is still a controversial topic in cancer therapy. So, this study aimed to compare the effect of L-arginine treatment alone and in combination with 5-fluorouracil (5-FU) on the survival and angiogenesis of primary human umbilical vein endothelial cells (HUVECs) and the breast cancer cell line of MDA-MB-468. Combinations of L-arginine and 5-FU increased cell survival in HUVECs but i...

Adolescents and young adults aged 15 to 39 years who are diagnosed with cancer (AYA survivors) undergo a range of therapies for cancer cure but subsequently may be at risk of treatment-related infertility, and for female AYA survivors, adverse pregnancy outcomes. Future fertility is important to AYA survivors. Meeting their fertility goals requires awareness of this importance, knowledge of cancer treatment–related fertility risks, appropriate fertility counseling on these risks, and access to fertility care. Epidemiologic and dissemination and implementation research are needed to estimate more precise risks of trad...

Authors: Abstract The diagnosis of cancer in females younger than 20 years is rare, with the incidence of 17 cases per 100,000 individuals per year in the United States. Although advancements in cancer therapy have dramatically improved childhood cancer survival, gynecologists should be aware of the increased risk of adverse reproductive health effects from each type of therapy. Cancer and its treatment may have immediate or delayed adverse effects on reproductive health. Gynecologists may be consulted for the following issues: pubertal concerns; menstrual irregularities; heavy menstrual bleeding and anemia; sexu...

In this study, we investigate mitochondrial energetics and mtDNA methylation in senescent cells, and evaluate the potential of humanin and MOTS-c as novel senolytics or SASP modulators that can alleviate symptoms of frailty and extend health span by targeting mitochondrial bioenergetics. Exercise versus the Hallmarks of Aging https://www.fightaging.org/archives/2018/06/exercise-versus-the-hallmarks-of-aging/ The paper I'll point out today walks through the ways in which exercise is known to beneficially affect the Hallmarks of Aging. The Hallmarks are a list of the significant causes of aging that I dis...
