Non-V600E BRAF mutations and treatment for Hairy Cell Leukemia.

We found 18 patients with immunophenotype consistent with classic hairy cell leukemia (HCL) and BRAF mutations other than just V600E. Twelve had 1 non-V600E BRAF mutation and 6 had V600E with 1 (n=5) or 2 (n=1) non-V600E BRAF co-mutations.

Genome-wide lone strand adenine methylation in Deinococcus radiodurans R1: Regulation of gene expression through DR0643-dependent adenine methylation.

DNA methylation is a covalent modification of adenine or cytosine in the genome of an organism and is found in diverse microbes including the radiation resistant bacterium Deinococcus radiodurans R1. Although earlier findings have confirmed repression or de-repression of certain genes in adenine methyltransferase (DR_0643/Dam1) deficient D. radiodurans mutant however, the overall regulatory aspects of Dam1-mediated adenine methylation remain mostly unexplored.

Functional and regulatory aspects of oxidative stress response in X monosomy.

The partial/complete loss of one X chromosome in a human female leads to Turner syndrome (TS). TS individuals display a range of phenotypes including short stature, osteoporosis, ovarian malfunction, diabetes, and thyroid dysfunction. Epigenetic factors and regulatory networks are distinctly different in X monosomy (45, X).

N6-methyladenine and epigenetic immunity of Deinococcus radiodurans.

DNA methylation is ubiquitously found in all three domains of life. This epigenetic modification on adenine or cytosine residues serves to regulate gene expression or to defend against invading DNA in bacteria. Here, we report the significance of N6-methyladenine (6mA) to epigenetic immunity in Deinococcus radiodurans.

Construction, analysis and validation of co-expression network to understand stress adaptation in Deinococcus radiodurans R1.

Systems biology based approaches have been effectively utilized to mine high throughput data. In the current study, we have performed system-level analysis for Deinococcus radiodurans R1 by constructing a gene co-expression network based on several microarray datasets available in the public domain. This condition-independent network was constructed by Weighted Gene Co-expression Network Analysis (WGCNA) with 61 microarray samples from 9 different experimental conditions.

An exploration of microbial and associated functional diversity in the OMZ and non-OMZ areas in the Bay of Bengal.

Depletion of oxygen in certain marine areas creates oxygen minimum zones (OMZs), which can alter the species composition and abundance. We have carried out high-throughput 16S rRNA gene amplicon profiling from the Bay of Bengal (BOB) OMZ and non-OMZ areas. Typically, a total of 35 families of micro-organisms were identified as biomarkers for OMZ and non-OMZ regions in the BOB.

Thyroid function in depression.

Studies on thyroid functions were performed on patients suffering from depression. Thirty four cases of depression were studied for their thyroid function and showed a diminished level of T3 and T4 with concomitant rise in TSH (Thyroid Stimulating Hormone) level. This work showed that depressive patients had been suffering from sub-hypothyroidism.
