The armadillo repeat containing 5 (ARMC5) gene is part of a family of protein-coding genes that are rich in armadillo repeat sequences, are ubiquitously present in eukaryotes, and mediate interactions between proteins, playing roles in various cellular processes. Current research has demonstrated that reduced expression or absence of the ARMC5 gene in various tumor tissues can lead to uncontrolled cell proliferation, thereby inducing a range of diseases. The ARMC5 gene was initially extensively studied in the context of bilateral macronodular adrenocortical disease (BMAD), with harmful pathogenic variants in ARMC5 identified in approximately 50% of BMAD patients. With advancing research, scientists have discovered that ARMC5 pathogenic variants may also have potential effects on other diseases and could be associated with increased susceptibility to certain cancers. This review aims to present the latest research progress on how the ARMC5 gene plays its role in tumors. It outlines the basic structure of ARMC5 and the regions where it functions, as well as the diseases currently proven to be associated with ARMC5. Moreover, some evidence suggests its relation to embryonic development and the regulation of immune system activity. In conclusion, the ARMC5 gene is a crucial focal point in genetic and medical research. Understanding its function and regulation is of great importance for the development of new therapeutic strategies related to diseases associated with its pathogenic variants.

Obstetric nurses should improve their breastfeeding counselling skills based on the needs of lactating women and provide personalized breastfeeding counselling services.

OBJECTIVE To investigate the improvement effects of Arisaema Cum Bile on Parkinson’s disease （PD） model mice and its potential mechanism. METHODS Sixty male C57BL/6J mice were randomly divided into normal group， model group， Arisaema Cum Bile low-dose group [0.39 g/（kg·d）]， Arisaema Cum Bile high-dose group [1.56 g/（kg·d）] and positive control drug Levodopa tablet group [80 mg/（kg·d）]， with 12 mice in each group. Except that normal group was given constant volume of normal saline， other groups were given 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine [MPTP，35 mg/（kg·d）] intraperitoneally for 5 consecutive days to induce subacute PD model； after modeling， they were given relevant medicine continuously for 7 d； rod climbing test and line suspension test were performed 1 d before modeling， on the 5th day of modeling and after the last medication. The number of tyrosine hydroxylase （TH）-positive neurons in the substantia nigra of mice were measured by immunofluorescence； the levels of interleukin 1β （IL-1β） and tumor necrosis factor α（ TNF-α） in serum and the levels of IL- E-mail：qhwang668@sina.com 1β， TNF-α， cyclooxygenase-2 （COX-2） and inducible nitric oxide synthase （iNOS） in the substantia nigra of mice were measured by enzyme-linked immunosorbent assay. The expression levels of cAMP-dependent protein kinase catalytic subunit α （PKA C-α）， glutathione peroxidase 4 （GPX4） and ferritin heavy chain polypeptide 1 （FTH1） proteins in the substantia nigra of mice was measured by Western blot. RESULTS After last medicine， compared with the normal group， mice in the model group had significantly longer pole-climbing time （P＜0.01）， significantly lower line suspension scores （P＜0.01）， significantly fewer TH-positive neurons in the substantia nigra （P＜0.01）， significantly higher serum concentrations of IL-1β and TNF-α and nigrostriatal concentrations of IL-1β， TNF-α， COX-2 and iNOS （P＜0.01）， while lower protein expression levels of GPX4， PKA C-α and FTH1 in the substantia nigra （P＜0.05 or P＜0.01）. Compared with the model group， the above indexes of mice were significantly returned in Arisaema Cum Bile high-dose group （P＜0.05 or P＜ 0.01）. CONCLUSIONS Arisaema Cum Bile can improve motor impairment and reduce apoptosis of nigrostriatal TH neurons in MPTP-induced PD mice， and has neuroprotective effects on model mice； this may be related to its inhibition of neuroinflammation and the inhibition of ferroptosis by up-regulating PKA signaling pathway.
