Article Synopsis
  • Lung adenocarcinoma (LUAD) is a type of lung cancer with a low survival rate of less than 20% over five years, so researchers wanted to find reliable markers that can help diagnose or treat it better.
  • They used different methods, including analyzing gene data from cancer databases and studying how certain genes affect LUAD cells in the lab.
  • They discovered some important genes, mainly TGFBR2, which seems to help protect against LUAD, and their findings were confirmed using various tests, showing that this gene could be a key target for future treatments.

Article Synopsis
  • Dehydrocorydaline (DHC), an active component of a plant used in traditional medicine, shows promise in treating coronary heart disease due to its protective and pain-relieving effects, though the mechanism is not fully understood.
  • The study aimed to investigate whether DHC can mitigate myocardial ischemia-reperfusion injury (MIRI) by affecting the FoxO signaling pathway to reduce cell death (apoptosis).
  • Experimental results demonstrated that DHC improved heart function in a mouse model of MIRI and reduced apoptosis and oxidative stress in heart cells exposed to hypoxia, principally through the FoxO pathway.

Fibrosis is a process of tissue repair that results in the slow creation of scar tissue to replace healthy tissue and can affect any tissue or organ. Its primary feature is the massive deposition of extracellular matrix (mainly collagen), eventually leading to tissue dysfunction and organ failure. The progression of fibrotic diseases has put a significant strain on global health and the economy, and as a result, there is an urgent need to find some new therapies.

Cardiovascular diseases (CVDs) have been on the rise around the globe in the past few decades despite the existing guidelines for prevention and treatment. Short-chain fatty acids (SCFAs) are the main metabolites of certain colonic anaerobic bacterial fermentation in the gastrointestinal tract and have been found to be the key metabolites in the host of CVDs. Accumulating evidence suggest that the end-products of SCFAs (including acetate, propionate, and butyrate) interact with CVDs through maintaining intestinal integrity, anti-inflammation, modulating glucolipid metabolism, blood pressure, and activating gut-brain axis.

Pulmonary diseases are main causes of morbidity and mortality worldwide. Current studies show that though specific pulmonary diseases and correlative lung-metabolic deviance own unique pathophysiology and clinical manifestations, they always tend to exhibit common characteristics including reactive oxygen species (ROS) signaling and disruptions of proteostasis bringing about accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER). ER is generated by the unfolded protein response.

Ferroptosis is a programmed iron-dependent cell death characterized by accumulation of lipid peroxides (LOOH) and redox disequilibrium. Ferroptosis shows unique characteristics in biology, chemistry, and gene levels, compared to other cell death forms. The metabolic disorder of intracellular LOOH catalyzed by iron causes the inactivity of GPX4, disrupts the redox balance, and triggers cell death.

Myocardial ischemia is a disease with high morbidity and mortality, for which reperfusion is currently the standard intervention. However, the reperfusion may lead to further myocardial damage, known as myocardial ischemia/reperfusion injury (MI/RI). Oxidative stress is one of the most important pathological mechanisms in reperfusion injury, which causes apoptosis, autophagy, inflammation, and some other damage in cardiomyocytes through multiple pathways, thus causing irreversible cardiomyocyte damage and cardiac dysfunction.
