Systemic sclerosis (SSc) is a multisystem fibrotic and autoimmune disease. Both genetic and epigenetic elements mediate SSc pathophysiology. This review summarizes the role of one epigenetic element, known as microRNAs (miRNAs), involved in different signaling pathways of SSc pathogenesis. The expression of key components in transforming growth factor-β (TGF-β) signaling pathway has been found to be regulated by miRNAs both upstream and downstream of TGF-β. We are specifically interested in the pathway components upstream of TGF-β, while miRNAs in other signaling pathways have not been extensively studied. The emerging role of miRNAs in vasculopathy of SSc suggests a promising new direction for future investigation. Elucidation of the regulatory role of miRNAs in the expression of signaling factors may facilitate the discovery of novel biomarkers in SSc and improve the understanding and treatment of this disease.

Salt stress impairs photosynthetic efficiency and consequently reduces the growth, development, and grain yield of crop plants. The formation of hydrophobic barriers in the root endodermis, including the suberin lamellae and Casparian strips, is a key adaptive strategy for salt stress tolerance. In this study, we identified the role of the rice NAC transcription factor, ONAC005, in salt stress tolerance.

Plant thermomorphogenesis is a critical adaptive response to elevated ambient temperatures. The transcription factor PHYTOCHROME-INTERACTING FACTOR 4 (PIF4) integrates diverse environmental and phytohormone signals to coordinate thermoresponsive growth. However, the cellular mechanisms underlying plant thermomorphogenic growth remain poorly understood.

20(R)-ginsenoside Rg3 can reduce the effects of oxidative stress and cell death in cerebral ischemia‒reperfusion injury (CIRI). Neuroinflammation is crucial post-CIRI, but how 20(R)-Rg3 affects ischemia‒reperfusion-induced neuroinflammation is unclear. To study 20(R)-Rg3's effects on neuroinflammation and neuronal preservation in stroke models and explore toll-like receptor 4/myeloid differentiation factor-88/nuclear factor kappa B (TLR4/MyD88/NF-κB) pathway mechanisms.

RNA cap formation on RNA polymerase II transcripts is regulated by cellular signalling pathways during development and differentiation, adaptive and innate immune responses, during the cell cycle and in response to oncogene deregulation. Here, we discuss how the RNA cap methyltransferase, RNA guanine-7 methyltransferase (RNMT), functions to complete the 7-methyl-guanosine or m7G cap. The mechanisms by which RNMT is regulated by signalling pathways, co-factors and other enzymes are explored.

The prevalence of AGA is continuously rising, with an earlier age of onset. Currently, only minoxidil and finasteride have received FDA approval for the treatment of AGA, inadequately addressing the pressing clinical needs. Recently, the involvement of the Wnt/β-catenin signaling pathway in AGA has attracted increased research interest.
