Lamin B1 regulates RNA splicing factor expression by modulating the spatial positioning and chromatin interactions of the gene locus.

Lamin B1, a crucial component of the nuclear lamina, plays a pivotal role in chromatin organization and transcriptional regulation in eukaryotic cells. While recent studies have highlighted the connection between Lamin B1 and RNA splicing regulation, the precise molecular mechanisms remain elusive. In this study, we demonstrate that Lamin B1 depletion leads to a global reduction in splicing factor expression, as evidenced by analysis of multiple RNA-seq datasets.

Metabolomics and network pharmacology approach to identify potential bioactive compounds from Trichoderma sp. against oral squamous cell carcinoma.

This study aimed to profile metabolites from five Trichoderma strains and assess their cytotoxic and pharmacological activities, particularly targeting oral squamous cell carcinoma (OSCC). UHPLC-TOF-MS analysis revealed the presence of 25 compounds, including heptelidic acid, viridiol isomers, and sorbicillinol from the different Trichoderma extracts. Pharmacokinetic analysis showed moderate permeability and low interaction with P-glycoprotein, suggesting good drug absorption with minimal interference in cellular uptake.

Propylparaben-induced endoplasmic reticulum stress triggers G2/M phase cell cycle arrest and initiates caspase-3-dependent apoptosis in human lung cells.

Comparative study of cytotoxic Signaling pathways in H1299 cells exposed to alternative Bisphenols: BPA, BPF, and BPS.

Background: Bisphenols are prevalent in food, plastics, consumer goods, and industrial products. Bisphenol A (BPA) and its substitutes, bisphenol F (BPF) and bisphenol S (BPS), are known to act as estrogen mimics, leading to reproductive disorders, disruptions in fat metabolism, and abnormalities in brain development.

Objectives: Despite numerous studies exploring the adverse effects of bisphenols both and , the molecular mechanisms by which these compounds affect lung cells remain poorly understood.

Reorganization of H3K9me heterochromatin leads to neuronal impairment via the cascading destruction of the KDM3B-centered epigenomic network.

Histone H3K9 methylated heterochromatin silences repetitive non-coding sequences and lineage-specific genes during development, but how tissue-specific genes escape from heterochromatin in differentiated cells is unclear. Here, we examine age-dependent transcriptomic profiling of terminally differentiated mouse retina to identify epigenetic regulators involved in heterochromatin reorganization. The single-cell RNA sequencing analysis reveals a gradual downregulation of in cone photoreceptors during aging.

Organoids for the Study of Retinal Development and Developmental Abnormalities.

The cumulative knowledge of retina development has been instrumental in the generation of retinal organoid systems from pluripotent stem cells; and these three-dimensional organoid models, in turn, have provided unprecedented opportunities for retinal research and translational applications, including the ability to model disease in a human setting and to apply these models to the development and validation of therapeutic drugs. In this review article, we examine how retinal organoids can also contribute to our understanding of retinal developmental mechanisms, how this knowledge can be applied to modeling developmental abnormalities, and highlight some of the avenues that remain to be explored.
