Background: Skin cutaneous melanoma (SKCM) is the most common subtype of skin malignancy, with ever-increasing incidence, mortality, and disease burden. Dysregulation of JAK-STATs signaling pathway is involved in the pathogenesis and progression of cancers, thus affecting the prognosis of cancer patients. The function of JAKs in SKCM is still not clarified.
Methods: A total of five online portal (GEPIA, TIMER, GeneMANIA, LinkedOmics, and GSCALite) is used to mine the expression and gene regulation network JAK2 in SKCM.
Results: JAK2 expression was downregulated in SKCM and significantly associated with pathological stage and the prognosis of patients. The functions of JAK2 and associated genes were primarily involved in the DNA recombination, cell cycle checkpoint, metabolic process, NOD-like receptor signaling pathways, p53 signaling pathway and apoptosis. JAK2 level was significantly correlated with the abundance of immune cells and the level of immune biomarkers. Low expression of JAK2 were resistant to QL-VIII-58, TL-1-85, Ruxolitinib, TG101348 and Sunitinib.
Conclusions: Our results reveal the expression and gene regulation network of JAK2 in skin cutaneous melanoma, providing more evidences about the role of JAK2 in carcinogenesis.

Rac/Rop proteins, a kind of unique small GTPases in plants, play crucial roles in plant growth and development and in response to abiotic and biotic stresses. However, it is poorly understood whether cotton Rac/Rop protein genes are involved in mediating cotton resistance to Verticillium dahliae. Here, we focused on the function and mechanism of cotton Rac/Rop gene GhRac9 in the defense response to Verticillium dahliae infection.

Cigarette smoke extract (CSE)-induced airway mucus hypersecretion and inflammation are prominent features of chronic obstructive pulmonary disease (COPD). As a factor associated with inflammation regulation, T cell immunoglobulin and mucin domain-1 (TIM-1) is found to be involved in various inflammatory disorders such as asthma and COPD. In this study, the GEO database provides two human COPD gene expression datasets (GSE67472, n = 62) along with the relevant controls (n = 43) for differentially expressed gene (DEG) analyses.

In recent years, epigenetic modifications have attracted significant attention due to their unique regulatory mechanisms and profound biological implications. Acting as a bridge between environmental stimuli and changes in gene activity, they reshape gene expression patterns, providing organisms with regulatory mechanisms to respond to environmental changes. A growing body of evidence indicates that epigenetic regulation plays a crucial role in the pathogenesis and progression of psoriasis.

Titanium (Ti)-based materials are favored for hard tissue applications, yet their bioinertness limits their success. This study hypothesizes that functionalizing Ti materials with chitosan nano/microspheres and calcitriol (VD) will enhance their bioactivity by improving cellular activities and mineralization. To test this, chitosan particles were applied uniformly onto Ti surfaces using electrophoretic deposition (EPD) at 20 V for 3 minutes.

Cleft lip and palate (CL/P) are prevalent congenital anomalies with complex genetic causes. The G874A mutation of T-box transcription factor 22 (TBX-22) gene is notably associated with CL/P, while the underlying mechanism remains to be clarified. Studies have shown that the restriction of epithelial-mesenchymal transformation (EMT) process in medial edge epithelial cells (MEEs) is crucial for CL/P development.
