Profiling Molecular Changes of Host Response to Predict Outcome in Children with Septic Shock.

Background: Septic shock is associated with high mortality and there is significant heterogeneity in the host response. The aim of this study was to understand the genome-wide expression transcriptomic signatures in children with septic shock and correlate them with outcomes.

Methods: This was a prospective study conducted on children (aged 1 month to 18 years) admitted to the PICU (June-December 2021) with septic shock.

A systems biology investigation of curcumin potency against TGF-β-induced EMT signaling in lung cancer.

Unlabelled: Curcumin (diferuloylmethane) is bioactive phenolic compound which exerts diverse antimetastatic effect. Several studies have reported the antimetastatic effect of curcumin by its ability to modulate the epithelial-to-mesenchymal transition (EMT) process in different cancers, but underlying molecular mechanism is poorly understood. EMT is a highly conserved biological process in which epithelial cells acquire mesenchymal-like characteristics by losing their cell-cell junctions and polarity.

Expression of immune response genes in human corneal epithelial cells interacting with Aspergillus flavus conidia.

Background: Aspergillus flavus, one of the causative agents of human fungal keratitis, can be phagocytosed by human corneal epithelial (HCE) cells and the conidia containing phagosomes mature into phagolysosomes. But the immunological responses of human corneal epithelial cells interacting with A. flavus are not clear.

High-throughput metabolomic and transcriptomic analyses vet the potential route of cerpegin biosynthesis in two varieties of Ceropegia bulbosa Roxb.

Exploration with high-throughput transcriptomics and metabolomics of two varieties of Ceropegia bulbosa identifies candidate genes, crucial metabolites and a potential cerpegin biosynthetic pathway. Ceropegia bulbosa is an important medicinal plant, used in the treatment of various ailments including diarrhea, dysentery, and syphilis. This is primarily attributed to the presence of pharmaceutically active secondary metabolites, especially cerpegin.

Unravelling the genome of Holy basil: an "incomparable" "elixir of life" of traditional Indian medicine.

Background: Ocimum sanctum L. (O. tenuiflorum) family-Lamiaceae is an important component of Indian tradition of medicine as well as culture around the world, and hence is known as "Holy basil" in India.

Functional characterization of three water deficit stress-induced genes in tobacco and Arabidopsis: an approach based on gene down regulation.

Functional characterization of water deficit stress responsive genes is important to understand their role in stress tolerance. RNAi-based silencing of gene of interest and studying the stress response of knockdown plants under stress can be one of the potential options for assessing functional significance of these genes. Several genes showing higher transcript expression under water deficit stress were cloned earlier from a stress adapted crop species, groundnut.

Identification of specific let-7 microRNA binding complexes in Caenorhabditis elegans.

Little is known about the protein complexes required for microRNA formation and function. Here we used native gel electrophoresis to identify miRNA ribonucleoprotein complexes (miRNPs) in Caenorhabditis elegans. Our data reveal multiple distinct miRNPs that assemble on the let-7 miRNA in vitro.

siRNA. A guide for RNA silencing.

RNAi is routinely used to eliminate gene activity for experimental purposes. However, the precise molecular mechanism of RNAi is unknown. Recent papers partially illuminate this mechanism in human cells, advancing the potential application of RNAi toward the treatment of human disease.
