The c-H-ras proto-oncogene undergoes alternative splicing of the exon termed IDX giving rise to a novel protein of the Ras family, p19 (H-RasIDX). The experiment tests the effect on the transcriptome of overexpressing the wild type and W164A mutated forms of p19. Keywords: genetic modification Thre...
The monohaloacetic acids (monoHAAs) are generated as byproducts during the disinfection of drinking water and are cytotoxic, genotoxic, mutagenic, and teratogenic. Iodoacetic acid (IAA) toxicity was mitigated by antioxidants, suggesting the involvement of oxidative stress. Other monoHAAs may share a...
PARP-6, a member of a family of enzymes (17 in humans) known as poly-ADP- ribose polymerases (PARPs), is a neuronally enriched PARP. While previous studies from our group show that PARP-6 is a regulator of dendrite morphogenesis in hippocampal neurons, its function in the nervous system in vivo is p...
Individuals vary widely in their drug responses, which can be dangerous and expensive due to treatment delays and adverse effects. Growing evidence implicates the gut microbiome in this variability, however the molecular mechanisms remain largely unknown. We measured the ability of 76 diverse hum...
Mammalian genomes contain several billion base pairs of DNA which are packaged in chromatin fibers. At selected gene loci, cohesin complexes have been proposed to arrange chromatin fibers into higher-order structures, but it is poorly understood how cohesin performs this task, how important this fun...

Oxidative stress caused by Menadione or Hydrogen peroxide in synchronized Saccharomyces cerevisiae cultures. Alpha factor synchronized cultures (0.2-0.4 OD), treated at the beginning of S phase (25 min after release from G1 arrest) with either 2 mM Menadione (MD) or 0.24 mM Hydrogen peroxide (HP), s...
OBJECTIVE: To determine whether macrophages, a type of cell implicated in the pathogenesis of ankylosing spondylitis (AS), exhibit a characteristic gene expression pattern. METHODS: Macrophages were derived from the peripheral blood of 8 AS patients (median disease duration 13 years [range <1-43 yea...
