Core transcriptional regulatory circuitry molecule ZNF217 promotes AML cell proliferation by up-regulating MYB.

Leukemia is characterized by multiple rearrangements of signal transduction genes and overexpression of nonmutated genes, such as transcription factors (TFs) genes. Super-enhancers (SEs) are prevalent in human cancers and are associated with the accumulation of numerous core TFs. SEs drive the expression of core TF genes by delivering robust transcriptional activation signals.

Follicular regulatory T cells restrain kidney allograft rejection in mice by suppressing alloreactive B cells.

Pathogenic antibodies produced by alloreactive B cells mediate antibody-mediated rejection after kidney transplantation, but the mechanisms remain poorly understood. Follicular regulatory T (Tfr) cells modulate follicular helper T cell-mediated B cell responses, but the functions of Tfr in controlling alloreactive antibody are unknown. Here we study the developmental signals and functions of Tfr cells in mouse allogeneic kidney transplantation models, and show that costimulatory blockade alters the development of Tfr cells disproportionately by decreasing germinal center (GC)-like Tfr cells but increasing follicular-like Tfr cells.

IRF1 is a core transcriptional regulatory circuitry member promoting AML progression by regulating lipid metabolism.

Background: Acute myeloid leukemia (AML) is a prevalent malignancy of the hematologic system. Despite advancements in therapeutic approaches, significant heterogeneity and therapeutic resistance pose substantial challenges to treatment. Tumors driven by core transcription factors through super-enhancers can establish core transcriptional regulatory circuits (CRCs) that modulate oncogene expression programs.

A clinical prediction model for distant metastases of pediatric neuroblastoma: an analysis based on the SEER database.

Background: Patients with distant metastases from neuroblastoma (NB) usually have a poorer prognosis, and early diagnosis is essential to prevent distant metastases. The aim was to develop a machine-learning model for predicting the risk of distant metastasis in patients with neuroblastoma to aid clinical diagnosis and treatment decisions.

Methods: We built a predictive model using data from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2018 on 1,542 patients with neuroblastoma.

YkuR functions as a protein deacetylase in .

Protein acetylation is a common and reversible posttranslational modification tightly governed by protein acetyltransferases and deacetylases crucial for various biological processes in both eukaryotes and prokaryotes. Although recent studies have characterized many acetyltransferases in diverse bacterial species, only a few protein deacetylases have been identified in prokaryotes, perhaps in part due to their limited sequence homology. In this study, we identified YkuR, encoded by , as a unique protein deacetylase in .

Reversal of Hyperglycemia by Subcutaneous Islet Engraftment Using an Atelocollagen Sponge as a Scaffold.

Type 1 diabetes mellitus (T1DM) affects 8.4 million people worldwide, with patients primarily relying on exogenous insulin injections to maintain blood glucose levels. Islet transplantation via the portal vein has allowed for the direct internal release of insulin by glucose-sensitive islets.

Identification and validation of reference genes for RT-qPCR analysis in under Cd stress.

Gene expression is studied using RT-qPCR; however, there are no reference genes have been found for under Cd stress.

Nuclear receptor coactivator 7 (NCOA7) protects cancer cells from oxidative damage through its ERbd domain.

Oxidative stress causes damage to cancer cells and plays an important role in cancer therapy. Antagonizing oxidative stress is crucial for cancer cells to survive during the oxidation-based therapy. In this study, we defined the role of nuclear receptor co-activator 7 (NCOA7) in anti-oxidation in lung cancer cells and found that NCOA7 protects lung cancer A549 cells from the oxidative damage caused by hydrogen peroxide.

Competitive dynamics and balance between and commensal streptococci in oral microecology.

Circular Chromosome Conformation Capture (4C-Seq) Analysis of HBV-Host Chromosome DNA Interactome.

Hepatitis B virus (HBV) infects hepatocytes that are in the G0/G1 phase with intact nuclear membrane and organized chromosome architecture. In the nucleus of the infected cells, HBV covalently closed circular (ccc) DNA, an episomal minichromosome, serves as the template for all viral transcripts and the reservoir of persistent infection. Nuclear positioning of cccDNA can be assessed by the spatial distance between viral DNA and host chromosomal DNA through Circular Chromosome Conformation Capture (4C) combined with high-throughput sequencing (4C-seq).
