Unveiling FRG1's DNA repair role in breast cancer.

The FRG1(FSHD region gene 1) gene has emerged as a pivotal tumor suppressor in both breast and prostate cancer. HPF1 (Histone PARylation Factor 1), a gene crucial in the base excision repair (BER) mechanism for single-stranded DNA (ssDNA) lesions, showcases a robust correlation with FRG1. This implies that FRG1 might have the capacity to influence BER via HPF1, potentially playing a role in tumorigenesis.

Comparative miRNome and transcriptome analyses reveal the expression of novel miRNAs in the panicle of rice implicated in sustained agronomic performance under terminal drought stress.

Differential expression of 128 known and 111 novel miRNAs in the panicle of Nagina 22 under terminal drought stress targeting transcription factors, stress-associated genes, etc., enhances drought tolerance and helps sustain agronomic performance under terminal drought stress. Drought tolerance is a complex multigenic trait, wherein the genes are fine-tuned by coding and non-coding components in mitigating deleterious effects.

Epigenetic Modifications in Genome Help Remembering the Stress Tolerance Strategy Adopted by the Plant.

Genetic information in eukaryotic organisms is stored, replicated, transcribed, and inherited through the nucleus of a cell. Epigenetic modifications in the genetic material, including DNA methylation, histone modification, changes in non-coding RNA (ncRNA) biogenesis, and chromatin architecture play important roles in determining the genomic landscape and regulating gene expression. Genome architecture (structural features of chromatin, affected by epigenetic modifications) is a major driver of genomic functions/activities.

Epigenome editing for targeted DNA (de)methylation: a new perspective in modulating gene expression.

Traditionally, it has been believed that inheritance is driven as phenotypic variations resulting from changes in DNA sequence. However, this paradigm has been challenged and redefined in the contemporary era of epigenetics. The changes in DNA methylation, histone modification, non-coding RNA biogenesis, and chromatin remodeling play crucial roles in genomic functions and regulation of gene expression.

Salicylic Acid Conjugate of Telmisartan Inhibits Chikungunya Virus Infection and Inflammation.

There is no approved antiviral for the management of the Chikungunya virus (CHIKV). To develop an antiviral drug that can manage both CHIKV and arthritis induced by it, an ester conjugate of telmisartan (TM) and salicylic acid (SA) was synthesized (DDABT1). It showed higher potency (IC of 14.
