IL-10 down-regulates the expression of survival associated gene hspX of Mycobacterium tuberculosis in murine macrophage BJID
Jee,Babban; Sharma,Pawan; Katoch,Kiran; Joshi,Beenu; Awasthi,Sudhir Kumar.
Abstract Mycobacterium tuberculosis (MTB) adopts a special survival strategy to overcome the killing mechanism(s) of host immune system. Amongst the many known factors, small heat shock protein 16.3 (sHSP16.3) of MTB encoded by gene hspX has been reported to be critical for the survival of MTB. In the present study, the effect of recombinant murine interferon-gamma (rmIFN-γ) and recombinant murine interleukin-10 (rmIL-10) on the expression of gene hspX of MTB in murine macrophage RAW264.7 has been investigated. By real-time RT-PCR, it was observed that three increasing concentrations (5, 25 and 50 ng/ml) of rmIFN-γ significantly up-regulated the expression of hspX whereas similar concentrations of rmIL-10 (5, 25 and 50 ng/ml) significantly down-regulated...

A simple and rapid method of sample preparation from culture filtrate of M. tuberculosis for two-dimensional gel electrophoresis BJM
Kumar,Gavish; Shankar,Hari; Bisht,Deepa; Sharma,Prashant; Singhal,Neelja; Katoch,V.M.; Joshi,Beenu.
Sample preparation for Two-dimensional gel electrophoresis (2DE) is tedious and not sufficient to provide a comparative profile of secreted proteins for various strains of M. tuberculosis. High lipid content in mycobacteria limits the use of common methods as it can hinder the 2DE run. This study highlights the significance of SDS-TCA procedure over common used methods for the preparation of sample from culture filtrate as well as other proteinaceous fluids.
