In addition, overexpressed WT CyPA, but not CyPA with a rotamase active site point mutation, protected cells expressing ALS-related mutant SOD from death.
The presence of nuclear IRS-1/Rad51 complexes was strongly associated with the inhibition of HRR and with the increased incidence of spontaneous mutations in cells expressing JCV T-Antigen (10).
Like all organisms, this bacterium has a characteristic mutation frequency, and cells expressing AID, APOBEC1, APOBEC3C, or APOBEC3G were shown to elicit 4- to 20-fold higher mutation frequencies.
Both DBC, a potent liver and skin carcinogen, and N-MeDBC, a specific sarcomagen, increased significantly (P<0.001) the frequency of 6-TGr mutations in V79MZh1A1 cells, expressing the human CYP1A1; in contrast, a strict hepatocarcinogen diMeDBC was devoid of any activity.
Independent of the mutation, EGFRhigh cells expressed significantly higher levels of Egfr transcripts than corresponding EGFRlow cells (Fig. 4E), which is consistent with previous observations (Carrillo-García et al., 2010).
Figure 1B (and Movie S1) shows a mixture of B. subtilis protoplasts containing a repressible P xyl -murE construct (acts as a class 1 mutation) with (ispA−; red cells expressing mCherry) or without (ispA+; unlabelled cells) an ispA mutation trapped in the channels.
To further evaluate the tumorigenic potential of MLK3 missense mutations in vivo, NIH3T3 cells expressing P252H and R799C mutants, which were the most transforming mutations in vitro and found in two distinct key functional domains (the kinase and the P/S/T-rich domains, respectively) were inoculated subcutaneously in nude mice.
These in vitro effects suggest that the absence of hyperplasia in subjects with G151E mutations is attributable to increased cell death in cells expressing this mutation in vivo, limiting the glomerulosa cell mass, and likely accounting for the absence of progressive disease.
Cells expressing mutations in lamina genes also cluster according to their biological definition.
Our lamina-based quantitative imaging method provides a robust and effective method for different cell types and cells expressing mutations in lamina genes.
