exon 20 insertion mutation and exon 14 skipping mutation in non-small cell lung cancer: a scoping review in the Chinese population.

Background: Epidermal growth factor receptor () and mesenchymal-epithelial transition () gene mutations are well established in the pathogenesis of non-small cell lung cancer (NSCLC). However, there is limited understanding about the impact of rare variants, such as exon 20 insertion mutation (ex20ins) and exon 14 skipping mutation (ex14) in the Chinese population even though targeted therapies have been approved in China. We conducted a scoping review to assess the current available evidence of these two mutations in NSCLC in the Chinese population.

Disruption of local circadian clocks in aristolochic acid-induced nephropathy in mice.

Background: Aristolochic acid I (AAI), an emerging biogenic contaminant widely present in Aristolochic plants, has been implicated in the progression of tubulointerstitial disease, known as aristolochic acid nephropathy (AAN). The circadian clock, a vital regulator of organ homeostasis, is susceptible to external chemical cues, including toxins. However, the reciprocal interactions between AAI and the circadian clock remain unexplored.

Kinetic Characterization of Estradiol Glucuronidation by Liver Microsomes and Expressed UGT Enzymes: The Effects of Organic Solvents.

Background And Objective: In vitro glucuronidation of 17β-estradiol (estradiol) is often performed to assess the role of uridine 5'-diphospho-glucuronosyltransferase 1A1 (UGT1A1) in xenobiotic/drug metabolism. The objective of this study was to determine the effects of four commonly used organic solvents [i.e.

Continuous genetic monitoring of transient mesenchymal gene activities in distal tubule and collecting duct epithelial cells during renal fibrosis.

Epithelial cells (ECs) have been proposed to contribute to myofibroblasts or fibroblasts through epithelial-mesenchymal transition (EMT) during renal fibrosis. However, since EMT may occur dynamically, transiently, and reversibly during kidney fibrosis, conventional lineage tracing based on Cre-loxP recombination in renal ECs could hardly capture the transient EMT activity, yielding inconsistent results. Moreover, previous EMT research has primarily focused on renal proximal tubule ECs, with few reports of distal tubules and collecting ducts.

Design, synthesis, and evaluation of 2,2'-bipyridyl derivatives as bifunctional agents against Alzheimer's disease.

Alzheimer's disease (AD) is a complex multifactorial neurodegenerative disease. Metal ion dyshomeostasis and Aβ aggregation have been proposed to contribute to AD progression. Metal ions can bind to Aβ and promote Aβ aggregation, and ultimately lead to neuronal death.

Knockdown of NogoA prevents MPP+‑induced neurotoxicity in PC12 cells via the mTOR/STAT3 signaling pathway.

NogoA is a myelin‑associated protein, which is important in the inhibition of axonal fiber growth and in regeneration following injury of the mammalian central nervous system. A previous study suggested that NogoA may be key in the process of Parkinson's disease (PD), which is the second most common chronic neurodegenerative disorder worldwide. The regulatory mechanism underlying the effect of NogoA on the process of PD remains to be fully elucidated.

Effects of Nogo-A Silencing on TNF-α and IL-6 Secretion and TH Downregulation in Lipopolysaccharide-Stimulated PC12 Cells.

Parkinson's disease (PD) is a common degenerative disease that lacks efficient treatment. Myelin-associated neurite outgrowth inhibitor A (Nogo-A) is relevant with inhibition of nerve regeneration and may play vital role in pathogenesis of PD. The study aimed to establish the shRNA expression plasmids of Nogo-A gene and explore the regulatory effects of Nogo-A silencing on the expression of inflammation factor tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) as well as tyrosine hydroxylase (TH) in lipopolysaccharide- (LPS-) stimulated rat PC12 cells.
