Osteoarthritis (OA) is a common chronic inflammatory degenerative disease. Since chondrocytes are the only type of cells in cartilage, their survival is critical for maintaining cartilage morphology. This review offers a comprehensive analysis of how reactive oxygen species (ROS), including superoxide anions, hydrogen peroxide, hydroxyl radicals, nitric oxide, and their derivatives, affect cartilage homeostasis and trigger several novel modes of regulated cell death, including ferroptosis, parthanatos, and oxeiptosis, which may play roles in chondrocyte death and OA development. Moreover, we discuss potential therapeutic strategies to alleviate OA by scavenging ROS and provide new insight into the research and treatment of the role of regulated cell death in OA.

It is known that inhibition of the endoplasmic reticulum transmembrane signaling protein (ERN1) suppresses the glioblastoma cells proliferation. The present study aims to investigate the impact of inhibition of ERN1 endoribonuclease and protein kinase activities on the , , and gene expression in U87MG glioblastoma cells with an intent to reveal the role of ERN1 signaling in the regulation of expression of these genes. The U87MG glioblastoma cells with inhibited ERN1 endoribonuclease (dnrERN1) or both enzymatic activities of ERN1 (endoribonuclease and protein kinase; dnERN1) were used.

For the effective growth of malignant tumors, including glioblastoma, the necessary factors involve endoplasmic reticulum (ER) stress, hypoxia, and the availability of nutrients, particularly glucose. The ER degradation enhancing alpha-mannosidase like protein 1 (EDEM1) is involved in ER-associated degradation (ERAD) targeting misfolded glycoproteins for degradation in an N-glycan-independent manner. EDEM1 was also identified as a new modulator of insulin synthesis and secretion.

Background And Aims: Portal vein tumor thrombosis (PVTT), an indicator of clinical metastasis, significantly shortens hepatocellular carcinoma (HCC) patients' lifespan, and no effective treatment has been established. We aimed to illustrate mechanisms underlying PVTT formation and tumor metastasis, and identified potential targets for clinical intervention.

Approach And Results: Multi-omics data of 159 HCC patients (including 37 cases with PVTT) was analyzed to identify contributors to PVTT formation and tumor metastasis.

The translocation dynamics of cells and particles through geometric constrictions are critical in biological and biomedical processes from splenic filtration to tumor metastasis. While particle stiffness plays a key role, its role in highly nonequilibrium states remains poorly understood. Here, we present a multiscale model to investigate the impact of particle stiffness on the translocation dynamics in microfluidic channels.

Obesity is associated with comorbidities including type 2 diabetes, chronic nonhealing wounds, and psoriasis. Normally, skin homeostasis and repair is regulated through the production of cytokines and growth factors derived from skin-resident cells including epidermal γδ T cells. However, epidermal γδ T cells exhibit reduced proliferation and defective growth factor and cytokine production during obesity and type 2 diabetes.
