The phyto-hormone, naphthalene acetic acid was shown to prompt maximum up regulation (1.

-Derived Phytopharmaceutical Drug Has Potent Anti-dengue Activity.

Dengue is a serious public health concern worldwide, with ∼3 billion people at risk of contracting dengue virus (DENV) infections, with some suffering severe consequences of disease and leading to death. Currently, there is no broad use vaccine or drug available for the prevention or treatment of dengue, which leaves only anti-mosquito strategies to combat the dengue menace. The present study is an extension of our earlier study aimed at determining the and protective effects of a plant-derived phytopharmaceutical drug for the treatment of dengue.

Transcriptome-wide identification of squalene epoxidase genes from Glycyrrhiza glabra L.: expression analysis and heterologous expression of GgSQE1 suggest important role in terpenoid biosynthesis.

Squalene epoxidase (SQE) is a crucial regulatory enzyme for the biosynthesis of several important classes of compounds including sterols and triterpenoids. The present paper identified and characterised five SQE genes (GgSQE1 to GgSQE5) from Glycyrrhiza glabra through transcriptome data mining and homology-based cloning, for the first time. The phylogenetic analysis implied their functional divergence.

Indolylkojyl methane analogue IKM5 potentially inhibits invasion of breast cancer cells via attenuation of GRP78.

Purpose: More than 90% of the breast cancer deaths occur due to the metastasis of the cancer cells to secondary organ sites. Increased Glucose-regulated protein 78 (GRP78) expression is critical for epithelial-mesenchymal transition (EMT) and invasion in breast cancer resulting in poor patient survival outcomes. Therefore, there is an urgent need of potential inhibitors of GRP78 for the abrogation of invasion and metastasis in breast cancer.

Modulation of dietary folate with age confers selective hepatocellular epigenetic imprints through DNA methylation.

The present study has been designed to determine the effect of folate modulation (deficiency/supplementation) with aging on the promoter methylation of tumor suppressor and proto-oncogenes to understand the underlying mechanism of epigenetic alterations. Folate deficiency was induced for 3 and 5 months in weanling, young and adult groups, and after 3 months of folate deficiency, they were repleted with physiological folate (2 mg/kg diet) and folate oversupplementation (8 mg/kg diet) for another 2 months. The methylation facet in the present study revealed that the combined effect of folate deficiency and aging decreased the methylation index.
