RNA modifications in plant adaptation to abiotic stresses.

Epitranscriptomic chemical modifications of RNAs have emerged as potent regulatory mechanisms in the plant stress adaptation process. Currently, over 170 distinct chemical modifications have been identified in mRNAs, tRNAs, rRNAs, microRNAs (miRNAs), and long-noncoding RNAs (lncRNAs). The genetic and molecular studies have identified the genes responsible for adding and removing chemical modifications on RNA molecules, known as "writers" and "erasers," respectively.

Denatonium inhibits RANKL-induced osteoclast differentiation and rescues the osteoporotic phenotype by blocking p65 signaling pathway.

Background: Bone remodeling is a critical process that maintains skeletal integrity, orchestrated by the balanced activities of osteoclasts, which resorb bone, and osteoblasts, which form bone. Osteoclastogenesis, the formation of osteoclasts, is primarily driven by NFATc1, a process activated through c-Fos and NF-κB signaling pathways in response to receptor activator of nuclear factor κB ligand (RANKL). Dysregulation of RANKL signaling is a key contributor to pathological bone loss, as seen in conditions such as osteoporosis.
