Article Abstract
MicroRNAs (miRNAs) are the central component of an important layer of post-transcriptional regulation of gene expression. In plants, miRNAs target the transcripts in a manner that is generally highly sequence complementary. Extensive research is being made to study the genome-wide miRNA-mediated regulation of gene expression, which has resulted in the development of many tools for an in-silico prediction of miRNA targets. Although several tools have been developed for predicting miRNA targets in model plants, genome-wide analysis of miRNA targets is still a challenge for non-model species that lack dedicated tools. Here, we describe a computational procedure for studying miRNA-mediated interactions in plants, which is based on the fact that canonical miRNA target sites are highly complementary, the miRNAs negatively regulate the expression of their target genes and that miRNAs may form regulatory networks as one miRNA may target more than one transcript and vice-versa to modulate and fine-tune expression of the genome.

Oligomeric proanthocyanidins (OPCs), condensed tannins found plentiful in grape seeds and berries, have higher bioavailability and therapeutic benefits due to their low degree of polymerization. Recent evidence places OPCs as effective modulators of cancer stem cell (CSC) plasticity and tumor growth. Mechanistically, OPCs orchestrate multi-pathway inhibition by destabilizing Wnt/β-catenin, Notch, PI3K/Akt/mTOR, JAK/STAT3, and Hedgehog pathways, triggering β-catenin degradation, silencing stemness regulators (OCT4, NANOG, SOX2), and stimulating tumor-suppressive microRNAs (miR-200, miR-34a).

Background: The roles of long non-coding RNAs (lncRNAs) in the progression of various human tumors have been extensively studied. However, their specific mechanisms and therapeutic potential in Triple-Negative Breast Cancer (TNBC) remain to be fully elucidated.
Materials And Methods: The qRT-PCR assay was utilized to assess the relative mRNA levels of TFAP2A-AS1, PHGDH, and miR-6892.

Unlabelled: Cholesterol 25-hydroxylase (CH25H), an interferon-stimulated gene (ISG), has been implicated in broad-spectrum antiviral immunity. Here, we identify CH25H as a potent suppressor of hepatitis B virus (HBV) replication that significantly outperforms IFN-α in reducing HBV DNA, pregenomic RNA (pgRNA), HBsAg, and HBeAg, without inducing cytotoxicity. However, CH25H is weakly expressed in hepatocytes and only modestly induced by type I interferon.

Background: Insulinoma, the most common type of pancreatic endocrine tumor, frequently induces hypoglycemia due to persistent hyperinsulinemia. Although Mi-Lnc70 expression progressively increases during pancreatic maturation in mice, the biological role of Mi-Lnc70 in pancreatic β cells remains elusive.
Aim: This study was designed to investigate the role of LncRNA-Mi-Lnc70 in the mouse pancreatic β-cell line MIN6.
