Reducing signalling through mTORC1 by pharmacological treatment, mutations, restricted calorie intake or low protein:carbohydrate macronutrient ratio enhances metabolic health and increases life span in many species up to mammals.
A prognostic role for TP53 mutations restricted to the paclitaxel-treated subgroup was indirectly supported by the observation of an inferior prognosis also among patients being either heterozygote or homozygote for the MDM2 SNP 309G allele.
CC-stabilizing and -destabilizing mutations restricted to the polyQ stretch induced much weaker phenotypes than those determined by the same mutations in the polyA stretch.
A study now explores how clonal expansion of epidermal stem cells with specific oncogenic mutations might be restricted by their elimination through enforced differentiation.
On occasion, we have observed that the covariation-corrected analysis identifies mutations in epitopes restricted by the same HLA allele as being "linked", when in fact a more likely explanation is that that they arise due to HLA-restricted targeting and escape within multiple epitopes, either simultaneously or sequentially over the disease course [27], [32], [44], [45], [46], [47].
Indeed, studies analyzing viral evolution in patients infected with a known viral source or during the early infection phase have demonstrated the emergence of escape mutations within epitopes restricted by HLA class I alleles.
Sequence changes away from the HIV-1 subtype B consensus, including escape mutations in predicted CTL epitopes restricted by the HLA type of the recipient, were considered forward mutations.
Sequence changes away from the subtype B HIV-1 consensus sequence, including escape mutations in predicted CTL epitopes restricted by the HLA type of the recipient, were considered forward mutations.
The vast majority of T242X mutations were T242N, known as an escape mutation from CTL (TSTLQEQIGW: TW10), restricted by the protective HLA alleles B*57 and B*5801 in the setting of clade B and C infections.
Mutations in predicted epitopes that were restricted by the donor HLA type were considered potential CTL escape mutations (Fig 1, left panels, donor).
