LINC00626 drives tamoxifen resistance in breast cancer cells by interaction with UPF1.

Although tamoxifen is commonly utilized as adjuvant therapy for Estrogen Receptor alpha (ERα)-positive breast cancer patients, approximately 30-50% of individuals treated with tamoxifen experience relapse. Therefore, it is essential to investigate additional factors besides ERα that influence the estrogen response. In this study, cross-analysis of databases were performed, and the results revealed a significant association between LINC00626 and ERα signaling as well as increased expression levels of this gene in tamoxifen-resistant cells.

Objective: The objective of this study is to assess the impact of nano platinum-hydrogen saline (Pt NPs + H) on oxygen-induced retinopathy (OIR) in neonatal rats, with the goal to contribute new insights into the therapeutic strategies for retinopathy of prematurity.
Methods: Pt NPs + H formulation was synthesized to address OIR in a rat model. Subsequent examination included the assessment of retinal blood vessel distribution and morphology through hematoxylin and eosin (HE) and isolectin B4 (IB4) staining techniques.

Ethnopharmacological Relevance: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the digestive tract, often accompanied by a high risk of recurrence and drug resistance. Huaier (Trametes robiniophila Murr), a traditional Chinese medicinal fungus, has demonstrated potent anticancer properties and is widely used as an adjuvant treatment for liver, breast, gastric, colon, and non-small cell lung cancers. However, its effects and molecular mechanisms in GIST remain unclear.

Mitochondrial dysfunction and ferroptosis play crucial roles in myocardial ischemia/reperfusion (I/R) following heart transplantation. Microsomal glutathione s transferase 1 (MGST1) is widely distributed in mitochondria and has a protective effect against ferroptosis, and its involvement in myocardial I/R injury has not yet been elucidated. In this study, donor hearts from C57BL/6 male mice were subjected to 12 h of ex-vivo cold ischemia treatment and transplanted into the abdomen of recipient mice for 24 h of reperfusion.

Growing evidence suggests that plant compounds are emerging as a tremendous source for slowing the onset and progression of Alzheimer's disease (AD). Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid with some hypoglycemic, anticancer, and antiinflammatory activities. However, the pharmacological effects of UNA on AD are still unknown.
