Fang Huang, Min Ni, Jing-Ming Zhang, Dong-Jie Li, Fu-Ming Shen
Angiotensin II (Ang II)-induced injury of vascular smooth muscle cells (VSMCs) serves an important role in hypertension and other cardiovascular disorders. Transient receptor potential melastatin 8 (TRPM8) is a thermally‑regulated Ca2+‑permeable channel that is activated by reduced body temperature. Although several recent studies have revealed the regulatory effect of TRPM8 in vascular tone and hypertension, the precise role of TRPM8 in dysfunction of vascular smooth muscle cells (VSMCs) induced by Ang II remains elusive...

Rheumatoid arthritis (RA) is an inflammatory and autoimmune disease that affects ~1% of the world's population. Although the precise mechanism of RA has yet to be elucidated, accumulating evidence suggests that fibroblast‑like synoviocytes (FLSs) serve critical roles in the initiation and progression of RA. However, the underlying molecular mechanisms of FLS proliferation have yet to be elucidated. Long noncoding‑interleukin‑7 receptor (lnc‑IL7R) has been recently identified, which is activated by lipopolysaccharide (LPS) stimulation and diminishes the LPS‑induced inflammatory response...
