Focal segmental glomerulosclerosis (FSGS) shares podocyte damage as an essential pathological finding. Several mechanisms underlying podocyte injury have been proposed, but many important questions remain. Rho-associated, coiled-coil-containing protein kinase 2 (ROCK2) is a serine/threonine kinase responsible for a wide array of cellular functions. We found that ROCK2 is activated in podocytes of adriamycin (ADR)-induced FSGS mice and cultured podocytes stimulated with ADR. Conditional knockout mice in which the ROCK2 gene was selectively disrupted in podocytes (PR2KO) were resistant to albuminuria, glomerular sclerosis, and podocyte damage induced by ADR injection. In addition, pharmacological intervention for ROCK2 significantly ameliorated podocyte loss and kidney sclerosis in a murine model of FSGS by abrogating profibrotic factors. RNA sequencing of podocytes treated with a ROCK2 inhibitor proved that ROCK2 is a cyclic nucleotide signaling pathway regulator. Our study highlights the potential utility of ROCK2 inhibition as a therapeutic option for FSGS.

Based on transcriptomics technology, this study investigated the molecular mechanisms of Xiangsha Liujunzi Decoction in treating chronic atrophic gastritis(CAG), which were confirmed through experimental validation. The CAG rat model was built by the MNNG composite multi-factor method, followed by a 90-day administration of Xiangsha Liujunzi Decoction. The study measured the rat body mass and 3-hour food intake in each group and observed the pathological changes in gastric tissue using HE staining.

Dysfunction of the alveolar endothelial barrier plays a crucial role in the pathogenesis of septic acute lung injury (ALI). orexin B is a neuropeptide derived from orexin neurons in the lateral hypothalamus and has multiple biological functions. However, the physiological function of orexin B in sepsis is less reported.

Atherosclerosis (AS) is the pathologic basis of many cardiovascular diseases (CVDs). Hydroxysafflor yellow A (HSYA) is a valuable natural food pigment that has been reported to have significant health-promoting abilities. However, the anti-AS efficacy and mechanisms of HSYA have not yet been characterized.

Objectives: This study aimed to investigate the effects of silencing Ras homolog family member C (RhoC) on the proliferation, apoptosis, invasion, migration, and epithelial-mesenchymal transition (EMT) of salivary adenoid cystic carcinoma (SACC) and its molecular mechanisms.
Methods: A total of 27 SACC lesions and normal salivary gland tissues that were surgically resected at Qingdao Municipal Hospital from January 1, 2019 to March 1, 2024 were selected, and the expression levels of RhoC were detected by Western blot and immunohistochemistry. Three small interfering RNA (siRNAs) were designed to target the RhoC gene sequence, transfected into SACC-LM and SACC-83 cell lines, and evaluated for transfection efficiency.

The maintenance of corneal transparency and normal vision is dependent on preservation of epithelial and endothelial cell layer homeostases. Different types of corneal injury can induce swelling and losses in transparency. Fuchs endothelial corneal dystrophy (FECD) is one type of injury that is commonly treated with rho-associated coiled-coil-containing protein kinase (ROCK) inhibitors.
