The Integrator complex is a multisubunit complex that participates in the processing of small nuclear RNA molecules in eukaryotic cells by cleaving the 3' end. In protein-coding genes, Integrator is a key regulator of promoter-proximal pausing, release, and recruitment of RNA polymerase II. Research on Integrator has revealed its critical role in the regulation of gene expression and RNA processing.

Humans possess a remarkable ability to rapidly access diverse information from others' faces with just a brief glance, which is crucial for intricate social interactions. While previous studies using event-related potentials/fields have explored various face dimensions during this process, the interplay between these dimensions remains unclear. Here, by applying multivariate decoding analysis to neural signals recorded with optically pumped magnetometer magnetoencephalography, we systematically investigated the temporal interactions between invariant and variable aspects of face stimuli, including race, gender, age, and expression.

Reactivation of fetal hemoglobin expression alleviates the symptoms associated with β-globinopathies, severe hereditary diseases with significant global health implications due to their high morbidity and mortality rates. The symptoms emerge following the postnatal transition from fetal-to-adult hemoglobin expression. Extensive research has focused on inducing the expression of the fetal γ-globin subunit to reverse this switch and ameliorate these symptoms.

Article Synopsis
  • The study focuses on the interaction between the conceptus and the maternal endometrium in ruminants, highlighting the importance of epidermal growth factor (EGF) for embryo implantation and pregnancy establishment.
  • Researchers examined the expression of EGF in the goat uterus during early pregnancy and found that its levels were regulated by FOXO1 and interferon tau (IFNT).
  • Results indicated high EGF expression in specific uterine tissues during crucial stages of pregnancy, with FOXO1 promoting EGF transcription, enhancing understanding of its regulatory mechanisms in early ruminant pregnancy.

In ruminants, IFN-tau (IFNT) regulates the production of prostaglandins (PG) in the endometrium, which is crucial for conceptus adhesion. However, the related molecular regulatory mechanisms remain unclear. Forkhead box O1 (FOXO1), a member of the FOXO subfamily of transcription factors, is known to be important for mouse implantation and decidualization.

N6-methyladenosine (m6A), an epigenetic modification on RNAs, plays an important role in many physiological and pathological processes. However, the involvement of m6A in goat uterus during early pregnancy remains largely unknown. In this study, we found that the total m6A level was increasing in goat uterus as early pregnancy progressed.

Multimodal neuroimaging plays an important role in neuroscience research. Integrated noninvasive neuroimaging modalities, such as magnetoencephalography (MEG), electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), allow neural activity and related physiological processes in the brain to be precisely and comprehensively depicted, providing an effective and advanced platform to study brain function. Noncryogenic optically pumped magnetometer (OPM) MEG has high signal power due to its on-scalp sensor layout and enables more flexible configurations than traditional commercial superconducting MEG.

Article Synopsis
  • The study investigates the role of uncoupling protein 2 (UCP2) in energy metabolism during early pregnancy in goats, highlighting its expression and hormone regulation in the uterus.
  • UCP2 is found to be expressed in the luminal and glandular epithelia of the goat uterus from day 0 to day 30 of pregnancy, with notably low expression on day 16, which is crucial for adhesion.
  • The research indicates that UCP2 is regulated by hormones like progesterone and estrogen, and its inhibition also affects the proliferation of endometrial epithelial cells, suggesting its importance in maintaining energy balance during early pregnancy.

Ruminants have a superficial implantation pattern. The extended conceptus attaches to the receptive endometrium to form the cotyledonary placenta. During the attachment, a large number of events occur at the maternal-fetal interface.

We identified abnormally methylated, differentially expressed genes (DEGs) and pathogenic mechanisms in different immune cells of RA and SLE by comprehensive bioinformatics analysis. Six microarray data sets of each immune cell (CD19 B cells, CD4 T cells and CD14 monocytes) were integrated to screen DEGs and differentially methylated genes by using R package "limma." Gene ontology annotations and KEGG analysis of aberrant methylome of DEGs were done using DAVID online database.

Purpose: The inhibition of Mus81, a critical DNA repair gene, is recently related to the chemosensitivity of several human cancer cells such as hepatocellular carcinoma (HCC) cells. However, the role of Mus81 knockdown in chemotherapy response of colon cancer cells remains largely unknown.

Methods And Materials: The effects of Mus81 knockdown by lentivirus-mediated short hairpin RNA in sensitivity of HCT116 and LS180 colon cancer cell lines to four therapeutic drugs, including cisplatin (CDDP), were evaluated by MTT assay as well as a mouse model.

Methyl methansulfonate and UV sensitive gene clone 81 (Mus81) is a critical DNA repair gene that has been implicated in development of several cancers including hepatocellular carcinoma (HCC). However, whether Mus81 can affect proliferation and survival of HCC remains unknown. In the present study, we demonstrated that the knockdown of Mus81 was associated with suppressed proliferation and elevated apoptosis of HCC cells in vitro and in vivo.
