Paternal Obesity-Induced H3K27me3 Elevation Leads to MANF-Mediated Transgenerational Metabolic Dysfunction in Female Offspring.

Paternal lifestyle and environmental exposures can alter epigenetic changes in sperm and play a critical role in the offspring's future health, yet the underlying mechanisms remain elusive. The present study established a model of paternal obesity and found that the increased levels of H3K27me3 in sperm persist into the 8-cell embryo stage, resulting in a transgenerational decrease of Manf, which causes endoplasmic reticulum stress and activates the GRP78-PERK-EIF2α-ATF4-CHOP axis. This consequently leads to impaired glucose metabolism and apoptosis in the liver of female offspring.

The Role of a C-Terminal Seven-Amino Acid Motif in TbCSV C3 Protein and Its Interaction With NbPOLA2 in Enhancing Viral Replication.

The C3 protein of tobacco curly shoot virus (TbCSV), a possible evolutionary intermediate between truly monopartite begomoviruses and those requiring satellite molecules for infectivity, has been identified as a viral replication enhancer (REn). However, the mechanisms underlying this enhancement are largely unknown. In this study, we generated two mutant infectious clones of TbCSV: one with a deletion of the 3' end region of the C3 gene that does not overlap with C2 (TbCSV) and another in which this region was replaced by a phylogenetically unrelated iLOV gene sequence (TbCSV).

A novel truncated fusion gene ::AC010198.2 in post-MPN acute myeloid leukemia caused by del(12)(p13p11).

The gene ETV6 has been confirmed to be a genetic susceptibility gene for thrombocytopenia and leukemia. Here, we report a long-chain noncoding RNA AC010198.2 as a novel fusion partner of ETV6, showing a karyotype of del(12)(p13p11), with poor prognosis in a post-MPN AML that has never been reported, which may be an vital initial event in the transformation of MPN to AML and deterioration of disease.

Copy number variant analysis improves diagnostic yield in a diverse pediatric exome sequencing cohort.

Exome sequencing is the current standard for diagnosing Mendelian disorders; however, it is generally not considered the first-line test for detecting copy number variants (CNVs). We retrospectively investigated the additional diagnostic yield by performing concurrent CNV analysis using exome data in a large and diverse pediatric cohort. Patients were referred from various sources with variable phenotypes.

Peptide-functionalized nanocapsules for targeted inhibition of β2-microglobulin amyloid aggregation.

Dialysis-related amyloidosis (DRA) is a severe complication in patients undergoing long-term dialysis, primarily driven by the deposition of β2-microglobulin (β2m) amyloid fibrils. The effective sequestration and removal of β2m from the bloodstream represent key therapeutic strategies for managing DRA. In this study, we developed a β2m-binding peptide (KDWSFYILAHTEF, denoted as CF)-functionalized nanocomposite (NC-CF), consisting of a protein nanocapsule surface modified with CF peptides to enable specific β2m binding.

YTHDF2 promotes ATP synthesis and immune evasion in B cell malignancies.

Long-term durable remission in patients with B cell malignancies following chimeric antigen receptor (CAR)-T cell immunotherapy remains unsatisfactory, often due to antigen escape. Malignant B cell transformation and oncogenic growth relies on efficient ATP synthesis, although the underlying mechanisms remain unclear. Here, we report that YTHDF2 facilitates energy supply and antigen escape in B cell malignancies, and its overexpression alone is sufficient to cause B cell transformation and tumorigenesis.
