A novel deep learning model for glioma epilepsy associated with the identification of human cytomegalovirus infection injuries based on head MR.

Purpose: In this study, a deep learning model was established based on head MRI to predict a crucial evaluation parameter in the assessment of injuries resulting from human cytomegalovirus infection: the occurrence of glioma-related epilepsy. The relationship between glioma and epilepsy was investigated, which serves as a significant indicator of labor force impairment.

Methods: This study enrolled 142 glioma patients, including 127 from Shengjing Hospital of China Medical University, and 15 from the Second Affiliated Hospital of Dalian Medical University.

Ferulic acid ameliorates hyperuricemia by regulating xanthine oxidase.

Hyperuricemia is characterized by elevated uric acid (UA) level in the body. The xanthine oxidase (XO) inhibitory ability is an important way to evaluate the anti-hyperuricemia effect of natural products. Ferulic acid (FA) is a phenolic acid compound, and it is a free radical scavenger with many physiological functions.

MiR-7 Functions as a Tumor Suppressor by Targeting the Oncogenes TAL1 in T-Cell Acute Lymphoblastic Leukemia.

Background: T-cell acute lymphoblastic leukemia is a hematologic malignancy characterized by T-cell proliferation, and in many cases, the ectopic expression of the oncogenic transcription factor T-cell acute lymphocytic leukemia protein 1 (TAL1). MicroRNA-7 has been shown to play a critical role in proliferation, migration, and treatment sensitivity in a diverse array of cancers. In this study, we sought to establish a novel link between microRNA-7 and T-cell acute lymphoblastic leukemia oncogenesis.

Increased lncRNA HOTAIR expression promotes the chemoresistance of multiple myeloma to dexamethasone by regulating cell viability and apoptosis by mediating the JAK2/STAT3 signaling pathway.

Multiple studies have shown that HOX antisense intergenic RNA (HOTAIR), an oncogenic long non‑coding RNA (lncRNA), is dysregulated in leukemia and is involved in tumor progression. The aim of the present study was to determine whether HOTAIR could serve as a novel biomarker for the diagnosis of multiple myeloma (MM), and to investigate its role in regards to MM cell viability and chemoresistance to dexamethasone (DEX). The results revealed that the expression of HOTAIR was significantly upregulated in serum, bone marrow and primary CD138+ cells from MM patients compared with those from normal controls as determined by qPCR.

NET1 Enhances Proliferation and Chemoresistance in Acute Lymphoblastic Leukemia Cells.

Acute lymphoblastic leukemia (ALL) is the most prevalent of pediatric cancers. Neuroepithelial cell-transforming 1 (NET1) has been associated with malignancy in a number of cancers, but the role of NET1 in ALL development is unclear. In the present study, we investigated the effect of NET1 gene in ALL cell proliferation and chemoresistance.

GDPD5, a target of miR-195-5p, is associated with metastasis and chemoresistance in colorectal cancer.

Purpose: Successful treatment of colorectal cancer (CRC) is greatly impeded by metastasis and chemoresistance, particularly to 5-fluoruracil (5-Fu), one of the staples of clinical intervention in advanced CRC. The purpose of this study is to determine whether the gene glycerophosphodiester phosphodiesterase domain containing 5 (GDPD5) contributes to CRC cell metastasis and 5-Fu resistance. Ultimately, we evaluated the ability of microRNA 195-5p (miR-195-5p) to reduce GDPD5 expression and thus to enhance CRC cell susceptibility to chemotherapy.

EspC forms a filamentous structure in the cell envelope of Mycobacterium tuberculosis and impacts ESX-1 secretion.

Pathogenicity of Mycobacterium tuberculosis (M. tb) is mediated by the ESX-1 secretion system, which exports EsxA and EsxB, the major virulence factors that are co-secreted with EspA and EspC. Functional information about ESX-1 components is scarce.

miR-187-5p Regulates Cell Growth and Apoptosis in Acute Lymphoblastic Leukemia via DKK2.

Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and causes a high rate of mortality in affected adults. Many subtypes of ALL exist with disruptions in distinct genetic pathways, including those regulated by miRNAs. Here we identify miR-187-5p as being highly upregulated in B-cell ALL and a driver of cellular proliferation and suppressor of apoptosis.

Mycobacterium tuberculosis Differentially Activates cGAS- and Inflammasome-Dependent Intracellular Immune Responses through ESX-1.

Cytosolic detection of microbial products is essential for the initiation of an innate immune response against intracellular pathogens such as Mycobacterium tuberculosis (Mtb). During Mtb infection of macrophages, activation of cytosolic surveillance pathways is dependent on the mycobacterial ESX-1 secretion system and leads to type I interferon (IFN) and interleukin-1β (IL-1β) production. Whereas the inflammasome regulates IL-1β secretion, the receptor(s) responsible for the activation of type I IFNs has remained elusive.

Ligand-induced compaction of the PEX5 receptor-binding cavity impacts protein import efficiency into peroxisomes.

Peroxisomes entirely rely on the import of their proteome across the peroxisomal membrane. Recognition efficiencies of peroxisomal proteins vary by more than 1000-fold, but the molecular rationale behind their subsequent differential import and sorting has remained enigmatic. Using the protein cargo alanine-glyoxylate aminotransferase as a model, an unexpected increase from 34 to 80% in peroxisomal import efficiency of a single-residue mutant has been discovered.
