Self-assembled Arginine-Glycine-Aspartic Acid Mimic Peptide Hydrogels as Multifunctional Biomaterials for Wound Healing.

Clinical management of nonhealing ulcers requires advanced materials that can enhance wound closure rates without relying on the release of drugs or other growth factors to obviate systemic deleterious side effects. In our previous work, we synthesized an integrin-binding cell adhesive M {Fmoc-FFβAR(K)βA-NH consisting of an RGD mimic, [R(K)], with an amide terminus}, M {Fmoc-FFβAR(K)βA-OH consisting of an RGD mimic, [R(K)], with acid terminus}, and M (Fmoc-FFβARGDβA-NH consisting of an RGD peptide, reference) with multifunctional activity. Here, we reported the synthesis, characterization, and performance of a reversed derivative, R-M (Fmoc-FFβA(K)RβA-NH consisting of an RGD mimic, [K(R)], with an amide terminus) of an antimicrobial cell adhesive peptide, M.

Antimicrobial resistance genes and associated mobile genetic elements in Escherichia coli from human, animal and environment.

The global rise of antimicrobial resistance (AMR) poses a significant threat to human health. The environment plays an essential role in transmission of antimicrobial resistance genes (ARGs) between human and animal. Bacterial communities harbour diverse ARGs, carried by mobile genetic elements (MGEs) like plasmids and insertion sequences (ISs).

Exploring the impact of 2-hydroxyestradiol on heme oxygenase-1 to combat oxidative stress in rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by joint inflammation driven by complex signaling pathways. Recent therapeutic approaches focus on small molecules targeting intracellular signaling to address specific physiological aspects of the disease. Previously we identified a small molecule, 2-hydroxyestradiol (2-OHE2), an inhibitor of TNF-α by an in-silico study.

Stem cell factor-mediated upregulation of SIRT1 protects melanin-deprived keratinocytes against UV-induced DNA damage in individuals with vitiligo.

Despite the loss of melanocytes, individuals with vitiligo have a significantly lower risk of developing skin malignancies compared to ethnicity-matched controls. The study investigated the molecular mechanisms that protect skin cells (keratinocytes) from UV-B-induced DNA damage in individuals with vitiligo. The study found that upregulation of stem cell factor (SCF) signaling significantly reduced γ-H2AX positivity and cyclobutane pyrimidine dimer formation and improved mitochondrial health (elongated mitochondria, reduced reactive oxygen species [ROS] and lipid peroxidation) in keratinocytes upon UV-B exposure.

Manganese pollution in eastern India causing cancer risk.

Groundwater poisoning by heavy metals has caused serious health hazards in the exposed population globally. Manganese (Mn) poisoning causing human health hazards is very meagerly reported worldwide. The present research elucidates for the first time the catastrophic effect of manganese causing cancer in the Gangetic plains of Bihar (India).

Feedback driven autonomous cycles of assembly and disassembly from minimal building blocks.

The construction of complex systems by simple chemicals that can display emergent network dynamics might contribute to our understanding of complex behavior from simple organic reactions. Here we design single amino acid/dipeptide-based systems that exhibit multiple periodic changes of (dis)assembly under non-equilibrium conditions in closed system, importantly in the absence of evolved biocatalysts. The two-component based building block exploits pH driven non-covalent assembly and time-delayed accelerated catalysis from self-assembled state to install orthogonal feedback loops with a single batch of reactants.

BRCAIndica: a resource for ACMG/AMP classified BRCA1 and BRCA2 variants.

As genetic testing becomes increasingly accessible and affordable, the uniform and accurate interpretation of genetic variants becomes essential. The ACMG/AMP joint guidelines provide the basis for systematic and uniform interpretation of pathogenicity of genetic variants. However, the application of these in routine clinical interpretation at-scale has largely been limited by the lack of resources providing harmonized data especially at a population-scale.

Background: Wilson's disease (WD) results from pathogenic ATP7B gene variations, causing copper accumulation mainly in the liver, brain, and kidneys.

Objectives: In India, despite studies on ATP7B variants, WD often goes undiagnosed, with the prevalence, carrier rate, and mutation spectrum remaining unknown.

Methods: A multicenter study examined genetic variations in WD among individuals of Indian origin via whole exome sequencing.

Mitochondrial calcium uptake orchestrates vertebrate pigmentation via transcriptional regulation of keratin filaments.

Mitochondria regulate several physiological functions through mitochondrial Ca2+ dynamics. However, role of mitochondrial Ca2+ signaling in melanosome biology remains unknown. Here, we show that pigmentation requires mitochondrial Ca2+ uptake.

VPS4A is the selective receptor for lipophagy in mice and humans.

Lipophagy is a ubiquitous mechanism for degradation of lipid droplets (LDs) in lysosomes. Autophagy receptors selectively target organelles for lysosomal degradation. The selective receptor for lipophagy remains elusive.

A cytoplasmic form of EHMT1N methylates viral proteins to enable inclusion body maturation and efficient viral replication.

Protein lysine methyltransferases (PKMTs) methylate histone and non-histone proteins to regulate biological outcomes such as development and disease including viral infection. While PKMTs have been extensively studied for modulating the antiviral responses via host gene regulation, their role in methylation of proteins encoded by viruses and its impact on host-pathogen interactions remain poorly understood. In this study, we discovered distinct nucleo-cytoplasmic form of euchromatic histone methyltransferase 1 (EHMT1N/C), a PKMT, that phase separates into viral inclusion bodies (IBs) upon cytoplasmic RNA-virus infection (Sendai Virus).

Here, we aim to define the microbial community structure and their functional profiles in the dengue positive patients with varying disease severity.

Methodology/principal Findings: Hospital admitted 112 dengue-positive patients blood samples were analyzed by dual RNA-sequencing to simultaneously identify the transcriptionally active microbes (TAMs), their expressed genes and associated pathways.

SCAR-6 elncRNA locus epigenetically regulates PROZ and modulates coagulation and vascular function.

In this study, we characterize a novel lncRNA-producing gene locus that we name Syntenic Cardiovascular Conserved Region-Associated lncRNA-6 (scar-6) and functionally validate its role in coagulation and cardiovascular function. A 12-bp deletion of the scar-6 locus in zebrafish (scar-6) results in cranial hemorrhage and vascular permeability. Overexpression, knockdown and rescue with the scar-6 lncRNA modulates hemostasis in zebrafish.
