TRIM29 reverses lenvatinib resistance in liver cancer cells by ubiquitinating and degrading YBX1 to inhibit the PI3K/AKT pathway.

Sorafenib and lenvatinib are frontline treatments for advanced hepatocellular carcinoma (HCC). While lenvatinib surpasses sorafenib in efficacy and tolerability, resistance remains a significant clinical challenge. Recent research highlights the potential of TRIM family proteins in modulating lenvatinib resistance in HCC, necessitating a deeper understanding of their specific mechanisms.

The trophectoderm (TE) is the first tissue to differentiate during the preimplantation development of the mammalian embryo. It forms the outer layer of the blastocyst and is responsible for generating the blastocoel, a fluid-filled cavity whose expansion is essential for successful hatching and implantation. Here, we investigated the role of the small GTPase RHOA in the morphogenesis of the TE, particularly its relationship with HIPPO signaling, using mouse embryos as a model.

Methods: A retrospective cross-sectional study of EMS 9-1-1 responses to children under 18 years for all causes over a 4-year period (2019-2022) reported in the National Emergency Medical Services Information System (NEMSIS) dataset. Data was stratified into three periods, Pre-pandemic, Pandemic and Reopening.
Stem cells prevent long-term deterioration of renal function after renal artery revascularization in a renovascular hypertension model in rats.
Sci Rep

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.

Objective: Aberrant 6-phosphofructo-2kinase/fructose-2,6-bisphoshatase 3 (PFKFB3) expression is tightly correlated with multiple steps of tumorigenesis; however, the pathological significance of PFKFB3 in macrophages in patients with rheumatoid arthritis (RA) remains obscure. In this study, we examined whether PFKFB3 modulates macrophage activation and promotes RA development.
Method: Peripheral blood mononuclear cells (PBMCs) from patients with RA, THP-1 cells, and bone marrow-derived macrophages from conditional PFKFB3-knockout mice were used to investigate the mechanism underlying PFKFB3-induced macrophage regulation of RA.
