Aurora B kinase plays an essential role in chromosome bi-orientation, which is a prerequisite for equal segregation of chromosomes during mitosis. However, it remains largely unclear whether centromere-localized Aurora B is required for faithful chromosome segregation. Here we show that histone H3 Thr-3 phosphorylation (H3pT3) and H2A Thr-120 phosphorylation (H2ApT120) can independently recruit Aurora B. Disrupting H3pT3-mediated localization of Aurora B at the inner centromere impedes the decline in H2ApT120 during metaphase and causes H2ApT120-dependent accumulation of Aurora B at the kinetochore-proximal centromere. Consequently, silencing of the spindle assembly checkpoint (SAC) is delayed, whereas the fidelity of chromosome segregation is negligibly affected. Further eliminating an H2ApT120-dependent pool of Aurora B restores proper timing for SAC silencing but increases chromosome missegregation. Our data indicate that H2ApT120-mediated localization of Aurora B compensates for the loss of an H3pT3-dependent pool of Aurora B to correct improper kinetochore–microtubule attachments. This study provides important insights into how centromeric Aurora B regulates SAC and kinetochore attachment to microtubules to ensure error-free chromosome segregation.
Significance Breast cancer stem cells (BCSCs) have the property of infinite self-renewal. When these cells divide, they give rise to one BCSC and one transient amplifying cell that can rapidly proliferate but only for a limited number of cell divisions. Only BCSCs can give rise to secondary (recurrent and/or metastatic) tumors. It is believed that breast cancer recurrence is due to the survival of a small number of BCSCs. Because the BCSCs represent a very small minority of cells within the primary tumor, their unique characteristics may not be detected by bulk tumor analyses. BCSCs are often located within regions of intratumoral hypoxia, and hypoxia-inducible factors activate the transcription of genes that promote BCSC specification and/or maintenance.

Abstract Abnormal expression or activity of proteins that regulate cell polarity can contribute to tumour progression. Discs large homolog ( DLG ) proteins play crucial roles in the maintenance of cell polarity and tissue morphogenesis. Previous studies of breast cancer patients showed that DLG 3 had greater expression in the cancerous tissues than non‐cancerous tissues, but the relationship between DLG 3 expression and breast cancer progression and prognosis is not clear. Here, we investigated the association of DLG 3 expression with breast cancer progression and prognosis using data on clinicopathological parameters from The Cancer Genome Atlas ( TCGA ) database, with different clinicopathological parameters using ualcan and LinkedOmics , and with different stages and subtypes using immunohistochemical staining. The results indicated greater DLG 3 expression in cancerous breast tissues than normal breast tissues and in luminal and Her2+ subtypes than in the triple‐negative subtype. DLG 3 expression also had a positive correlation with pathologic stage and decreased survival rate. Our data suggest that DLG 3 should be considered as a new diagnostic and prognostic biomarker for breast cancer.
The endoplasmic reticulum (ER) is a membrane-bounded organelle whose membrane comprises a network of tubules and sheets. The formation of these characteristic shapes and maintenance of their continuity through homotypic membrane fusion appears to be critical for the proper functioning of the ER. The atlastins (ATLs), a family of ER-localized dynamin-like GTPases, have been identified as fusogens of the ER membranes in metazoans. Mutations of the ATL proteins in mammalian cells cause morphological defects in the ER, and purified Drosophila ATL mediates membrane fusion in vitro. Plant cells do not possess ATL, but a family of similar GTPases, named root hair defective 3 (RHD3), are likely the functional orthologs of ATLs. In this review, we summarize recent advances in our understanding of how RHD3 proteins play a role in homotypic ER fusion. We also discuss the possible physiological significance of forming a tubular ER network in plant cells.
With the advantages of miniature damage and optimal effectiveness, percutaneous coronary intervention (PCI) has been performed in a large number of coronary artery disease patients. However, recent studies have indicated a higher incidence of depression on post-PCI patients. Acupuncture therapy is effective for depression. As a form of acupuncture, the auricular acupuncture has been used to relieve symptoms in patients with post-PCI depression, but its effectiveness and safety have not yet reached a definitive conclusion. Therefore, this systematic review and meta-analysis protocol is planned to evaluate the efficacy and safety of auricular acupuncture for depression in post-PCI patients.Six English databases (PubMed, Web of Science, MEDLINE, EMBASE, Springer Cochrane Library, and WHO International Clinical Trials Registry Platform) and 4 Chinese databases (Wan Fang Database, Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, and Chinese Biomedical Literature Database) will be searched normatively according to the rule of each database from the inception to February 1, 2022. Two reviewers will independently conduct article selection, data collection, and risk of bias evaluation. Any disagreement will be resolved by discussion with the third reviewer. Either the fixed-effects or random-effects model will be used for data synthesis based on the heterogeneity test. The change in the scores on the Hamilton Depression Scale and the Self-rating Depression Scale will be used as the main outcome measure. All-cause mortality, cardiac mortality, major adverse cardiovascular events, rehospitalisation rate, and Quality of Life Scale as the secondary outcome. Treatment Emergent Symptom Scale, general physical examination (temperature, pulse, respiration, blood pressure), routine examination of blood, urine and stool, electrocardiogram, liver and kidney function examination as the security indexes. RevMan 5.3.5 will be used for meta-analysis.This study will provide high-quality evidence to assess the efficacy and safety of auricular acupuncture for depression in post-PCI patients.This systematic review will explore whether auricular acupuncture is an effective and safe intervention for depression in post-PCI patients.INPLASY202230003.
In-stent restenosis (ISR) is the main factor affecting the outcome of percutaneous coronary intervention (PCI), and its main pathological feature is neointimal hyperplasia. Huotan Jiedu Tongluo decoction (HTJDTLD) is an effective traditional Chinese medicine (TCM) prescription for the treatment of vascular stenosis diseases. However, the precise anti-ISR mechanism of HTJDTLD remains unclear. Here, we investigated whether HTJDTLD can inhibit the excessive activation of endoplasmic reticulum stress (ERS) and reduce the level of autophagy factors through regulating the PERK-eIF2α-ATF4 pathway, thereby inhibiting the proliferation of the intima of blood vessels damaged by balloon injury (BI) and preventing the occurrence of ISR. In this study, a 2F Fogarty balloon was used to establish a common carotid artery (CCA) BI model in male Sprague-Dawley rats. Then, HTJDTLD (16.33 g/kg/d) or atorvastatin (1.19 mg/kg/d) was administered by gavage. Four weeks later, hematoxylin-eosin (HE) and Masson staining of the injured CCA were performed to observe the histological changes in the CCA. Immunohistochemistry (IHC) was used to assess the proliferation and dedifferentiation of vascular smooth muscle cells (VSMCs) in the CCA. Western blotting and RT-PCR were used to measure the expression of ERS- and autophagy-related proteins and mRNAs in the CCA. The results indicated that HTJDTLD significantly alleviated BI-induced carotid artery intimal hyperplasia and fibrosis and reduced the neointimal area (NIA) and NIA/medial area (MA) ratio. In addition, HTJDTLD inhibited the proliferation and dedifferentiation of VSMCs, reduced the expression of proliferating cell nuclear antigen (PCNA), and increased the smooth-muscle-α-actin- (SMα-actin-) positive area. HTJDTLD also significantly reduced the expression of the ERS-related factors: GRP78, p-PERK/PERK, p-eIF2α/eIF2α, ATF4, and CHOP. In addition, the expression of the autophagy-related factors, Beclin1, LC3B, and ATG12, was significantly decreased. In addition, in vitro experiments showed that HTJDTLD inhibited the above-mentioned ERS signal molecules in human umbilical vein endothelial cells (HUVEC) and rat aortic smooth muscle cells (A7R5) induced by tunicamycin (TM) and played a crucial role in protecting cells from damage. HTJDTLD may be a very promising drug for the treatment of ISR.
