Regulated transcription controls the diversity, developmental pathways and spatial organization of the hundreds of cell types that make up a mammal. Using single-molecule cDNA sequencing, we mapped transcription start sites (TSSs) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of mammalian gene… (More)
Mycobacterium tuberculosis is predicted to subsist on alternative carbon sources during persistence within the human host. Catabolism of odd- and branched-chain fatty acids, branched-chain amino acids, and cholesterol generates propionyl-coenzyme A (CoA) as a terminal, three-carbon (C(3)) product. Propionate constitutes a key precursor in lipid biosynthesis… (More)
Whole-cell screening of Mycobacterium tuberculosis (Mtb) remains a mainstay of drug discovery, but subsequent target elucidation often proves difficult. Conditional mutants that underexpress essential genes have been used to identify compounds with known mechanism of action by target-based whole-cell screening (TB-WCS). Here, the feasibility of TB-WCS in… (More)
Although it is generally accepted that cellular differentiation requires changes to transcriptional networks, dynamic regulation of promoters and enhancers at specific sets of genes has not been previously studied en masse. Exploiting the fact that active promoters and enhancers are transcribed, we simultaneously measured their activity in 19 human and 14… (More)
We observed vitamin B(12)-mediated growth inhibition of Mycobacterium tuberculosis strain CDC1551. The B(12) sensitivity was mapped to a polymorphism in metH, encoding a coenzyme B(12)-dependent methionine synthase. Vitamin B(12)-resistant suppressor mutants of CDC1551 containing mutations in a B(12) riboswitch upstream of the metE gene, which encodes a… (More)
Classical activation of macrophages (caMph or M1) is crucial for host protection against Mycobacterium tuberculosis (Mtb) infection. Evidence suggests that IL-4/IL-13 alternatively activated macrophages (aaMph or M2) are exploited by Mtb to divert microbicidal functions of caMph. To define the functions of M2 macrophages during tuberculosis (TB), we… (More)
In 92 patients the influence of duodenostasis on possibility of occurrence of rehemorrhage from duodenal ulcer was studied. It was established that the heightened risk of rehemorrhage is promoted by disorders of motility, blood flow and acid production.
Shown in the paper is a possibility of surgical correction of disturbances in the intestinal phase of gastric secretion in treating peptic ulcer and its complications which are encountered in an overwhelming majority of patients. Sympathectomy of relevant vascular trees is regarded as a pathogenetically validated procedure as is correction of duodenal… (More)
A modified classification of esophageal chemical burn and its consequences, based on the now existing classifications summary and the clinic experience analysis is presented.
The data concerning the disorder of the gastric secretion intestinal phase in patients with complicated forms of ulcer disease and with recurrent ulcer as well are presented. The mechanism was shown, which if noneliminated can cause nonfavourable result of the operation performed for the ulcer disease complications. The data presented trust the necessity of… (More)
