Landscape analysis of m5C modification regulators unveils DNMT1-mediated dysregulated pyrimidine metabolism in hepatocellular carcinoma.

The 5-methylcytosine (m5C) post-transcriptional modification has been linked with the development and progression of a variety of cancers. However, its specific functions and their underlying mechanisms are poorly understood in hepatocellular carcinoma (HCC). The present study showed abnormally increased levels of m5C modifications in HCC that were positively correlated with both HCC progression and worse patient prognosis.

YAP-activated NAT10 promotes hepatoblastoma progression by activating the pentose phosphate pathway.

Hepatoblastoma (HB) is the most common malignant liver tumor in children, with limited treatment options. The N4-acetylcytidine (ac4C) modification, an important mRNA post-transcriptional modification catalyzed by N-acetyltransferase 10 (NAT10), plays a crucial role in the initiation and progression of tumors. However, its impact on the development and prognosis of HB is largely unknown.

Separation of thoracic and abdominal measurements in neonatal vital sign monitoring using radar vision fusion system.

Non-contact, rapid and accurate measurement of respiratory rates (RR) and heart rates (HR) in neonates has significant clinical importance. Existing methods predominantly focus on thoracic respiratory signal measurement. This thoracic-focused approach, when applied to neonates who exhibit predominantly abdominal breathing, leads to a low signal-to-interference ratio (SIR) that compromises the accuracy of RR measurement compared with using abdominal signal.

LCAT deficiency promotes hepatocellular carcinoma progression and lenvatinib resistance by promoting triglyceride catabolism and fatty acid oxidation.

Lecithin cholesterol acyltransferase (LCAT), a crucial enzyme in lipid metabolism, plays important yet poorly understood roles in tumours, especially in hepatocellular carcinoma (HCC). In this study, our investigation revealed that LCAT is a key downregulated metabolic gene and an independent risk factor for poor prognosis in patients with HCC. Functional experiments showed that LCAT inhibited HCC cell proliferation, migration and invasion.

WWOX tuning of oleic acid signaling orchestrates immunosuppressive macrophage polarization and sensitizes hepatocellular carcinoma to immunotherapy.

Background: Immune checkpoint inhibitors (ICIs) are therapeutically effective for hepatocellular carcinoma (HCC) but are individually selective. This study examined the role of specific common fragile sites (CFSs) related gene in HCC immunotherapy.

Methods: We analyzed HCC tissues using next-generation sequencing and flow cytometry via time-of-flight technology.

Downregulation of Circ-PITHD1 Suppressed Colorectal Cancer via Glycolysis Inhibition through miR-590-5p/HK2 Axis.

Colorectal cancer (CRC) is a frequent malignancy around the globe. Circular RNAs (circRNAs) are implicated in CRC development. Nevertheless, the regulatory mechanisms and biological functions regarding circRNAs in CRC progression are largely unclear.

Hypervalent Iodine(III)-Promoted Radical Oxidative C-H Annulation of Arylamines with α-Keto Acids.

A novel catalyst-free radical oxidative C-H annulation reaction of arylamines with α-keto acids toward benzoxazin-2-ones synthesis under mild conditions was developed. This hypervalent iodine(III)-promoted process eliminated the use of a metal catalyst or additive with high levels of functional group tolerance. Hypervalent iodine(III) was both an oxidant and a radical initiator for this reaction.

LncRNA MEG3 inhibits the progression of prostate cancer by modulating miR-9-5p/QKI-5 axis.

This study was designed to detecting the influences of lncRNA MEG3 in prostate cancer. Aberrant lncRNAs expression profiles of prostate cancer were screened by microarray analysis. The qRT-PCR and Western blot were employed to investigating the expression levels of lncRNA MEG3, miR-9-5p and QKI-5.

Proteomics approach reveals novel proteins on the surface of malaria-infected erythrocytes.

Proteins on the surface of parasite-infected erythrocytes (PIESPs) have been one of the major focuses of malaria research due to their role in pathogenesis and their potential as targets for immunity and drug intervention. Despite intense scrutiny, only a few surface proteins have been identified and characterized. We report the identification of two novel surface proteins from Plasmodium falciparum-infected erythrocytes.

Inhibitory effect of selenium on Cryptosporidium parvum infection in vitro and in vivo.

The anticryptosporidial effect of sodium selenite (selenium) was evaluated in a bovine fallopian tube epithelial (BFrE) cell culture system and an immunosuppressed C57BL/6N adult mouse model. Parasite numbers in cell culture were significantly reduced (p<0.01) following treatment with selenium (Se) at concentrations of 6, 9, and 12 microM at 48 h postinoculation (PI) and at 1.
