Metformin inhibits pulmonary artery smooth muscle cell proliferation by upregulating p21 via NONRATT015587.2
Int J Mol Med. 2022 Apr;49(4):49. doi: 10.3892/ijmm.2022.5104. Epub 2022 Feb 11.ABSTRACTPulmonary artery hypertension (PAH) is a complex and progressive disease characterized by pulmonary vascular remodeling. Our previous study confirmed that NONRATT015587.2 could promote the proliferation of PASMCs and pulmonary vascular remodeling. However, the exact mechanism by which NONRATT015587.2 promotes PASMC proliferation is unclear. Bioinformatics analysis revealed that p21 is located at the downstream target of NONRATT015587.2. NONRATT015587.2 expression and localization were analyzed by PCR and fluorescence in situ hybridizati...

In conclusion, clinical trials targeting aging in humans have shown promising but limited results on biomarkers so far.
Mycobacterium Vaccae Immunization as an Anti-Inflammatory Strategy
https://www.fightaging.org/archives/2022/02/mycobacterium-vaccae-immunization-as-an-anti-inflammatory-strategy/
In today's open access paper, researchers discuss immunization with Mycobacterium vaccae as an approach to reduce the inflammatory overactivity of the aged immune system. Researchers have made some initial inroads into studying the way in which this bacteria can alter the function of the immune system, and here...

Conclusion
Coupled with the animal data, and the existing human trial data for safety, the results here suggests that someone should run a formal, controlled trial of flagellin immunization in older people, 65 and over. The goal would be to see whether (a) this sort of outcome holds up in a larger group of people, and (b) there is a meaningful impact on chronic inflammation and other parameters of health that are known to be affected by the aging of the gut microbiome.
The most interesting part of the data is perhaps the decline in microbial diversity, when considered against the gains elsewhere. Microbial dive...

Metformin enhances T lymphocyte anti-tumor immunity by increasing the infiltration via vessel normalization
Eur J Pharmacol. 2023 Feb 16:175592. doi: 10.1016/j.ejphar.2023.175592. Online ahead of print.ABSTRACTAbnormal tumor vasculature blocks the extravasation of T lymphocytes into the tumor, thereby suppressing anti-tumor immunity. Recently, metformin has been shown to affect tumor vasculature and enhance T lymphocyte anti-tumor immunity. However, whether or how metformin affects T lymphocyte anti-tumor immunity via a vascular mechanism remains poorly understood. Herein, we show that a large number of CD8+ lymphocytes gathered in the peri-tumoral region, while very few infiltrated the tumor. Metformin administration increased ...

This article reviews the current regulatory role of miR-7 in inflammation and related diseases, including viral infection, autoimmune hepatitis, inflammatory bowel disease, and encephalitis. It expounds on the molecular mechanism by which miR-7 regulates the occurrence of inflammatory diseases. Finally, the existing problems and future development directions of miR-7-based intervention on inflammation and related diseases are discussed to provide new references and help strengthen the understanding of the pathogenesis of inflammation and related diseases, as well as the development of new strategies for clinical interventi...

Metformin synergistically enhances antiproliferative effects of cisplatin and etoposide in NCI-H460 human lung cancer cells
CONCLUSIONS: Metformin, due to its independent effects on liver kinase B1, had antiproliferative effects on the NCI-H460 cell line. When metformin was combined with cisplatin or etoposide, the cell death rate was even higher. OBJETIVO: Testar a eficácia da combinação terapêutica de antineoplásicos convencionais (cisplatina e etoposÃdeo) com metformina em linhagem celular NCI-H460 de câncer de pulmão não pequenas células, a fim de desenvolver novas possibilidades terapêuticas com eficácia superior e reduzida toxicidade. MÉTODOS: Foi utilizado o ensaio de brometo de 3-(4,5-dimetiltiazol-2-il)-2,5-difeniltetrazÃ...

Law and Order? - Bristol-Myers-Squibb Settles Case Alleging Fraud and Kickbacks, No Admissions of Guilt, No Individuals Charged
Introduction Donald Trump, Republican candidate for the US presidency last week announced he is the " law and order " candidate, accompanied by then vice presidential contender and New Jersey Governor Chris Christie. I wonder if all this interest in law and order will lead to increasing the effectiveness of enforcing laws when large US health care corporations are accused? For years, we have been watching a parade of legal settlements made by big US health care organizations. These have included the biggest drug companies, biotechnology companies, device companies, insurance companies, etc, etc. ...

We examined associations between mortality and accelerometer-measured PA using age-relevant intensity cutpoints in older women of various ethnicities.
The results support the hypothesis that higher levels of accelerometer-measured PA, even when below the moderate-intensity threshold recommended in current guidelines, are associated with lower all-cause and CVD mortality in women aged 63 to 99. Our findings expand on previous studies showing that higher self-reported PA reduces mortality in adults aged 60 and older, specifically in older women, and at less than recommended amounts. Moreover, our findings challenge th...

In this study, senescent cell distribution and quantity in vastus lateralis muscle were examined in young human adults after a single bout of resistance exercise. To determine the effects of dietary protein availability around exercise on senescent cell quantity and macrophage infiltration of skeletal muscle, two isocaloric protein supplements (14% and 44% in calorie) were ingested before and immediately after an acute bout of resistance exercise, in a counter-balanced crossover fashion. An additional parallel trial was conducted to compare the outcome of muscle mass increment under the same dietary conditions after 12 wee...
