To confirm that disruption of Rv0431 caused the altered immune responses in macrophages, and to rule out effects due to secondary mutations, expression of Rv0431 was restored in Tn Rv0431 by complementation using the predicted promoter upstream of Rv0430.
We searched for microsatellite instability (MSI), presence of hMSH2 and hMLH1 germline mutations, expression of hMSH2, hMLH1 and p53 proteins in tumoural tissue samples by immunostaining.
Analyses of hyperplastic synovial tissues of patients with RA reveal features of transformed long-living cells such as the presence of somatic mutations, expression of oncogenes, and resistance to apoptosis [ 1- 3].
Recent work identified several genes required for the BRAFV600E-induced senescence and showed that in the context of BRAF mutation, expression loss of one of them, IGFBP7, is critical in promoting the progression to melanoma [23].
Although S112A was a loss-of-function mutation, membrane expression of the mutant was clearly detected, indicating that Ser is critical for the activity of mSlc10a2.
Consistent with the roles of PGL1, PGL2 and APG, the smg11 mutation decreased expression of PGL1 and PGL2 and increased expression of APG.
Microbes develop resistance to antibiotics as a result of chromosomal mutation, inductive expression of latent chromosomal genes, or exchange of genetic material via transformation, bacteriophage transduction, or plasmid conjugation [10 12].
However, these findings contrast with a recent report of the phenotypic effect of ciaRH mutation on expression of htrA in transparent and opaque variants [58].
Other reports have suggested that the impact of the tcaR mutation on expression of sarS also has a profound impact on S. aureus regulatory circuits [22], [50].
