The rainforests of Southeast Asia, the habitat of most gibbon species, have often been subjected to contractions and expansions, which favored repeated isolation and unification of different populations (Morley and Flenley 1987).
On the contrary, IRs represent hotspots for structural rearrangements within the cp genome (Wicke et al. 2011), because they are frequently subject to expansion, contraction, or even complete loss as mentioned earlier.
When ageing muscles are subjected to eccentric contractions (contractions with stretch), they experience greater damage than muscles from younger animals [14] [15], [23].
But the gray zone, while subject to periods of contraction, is still officially tolerated and indeed functions as a safety valve, helping to preserve the government by providing outlets for dissatisfaction and space for creative thinking about the future.
Repetitive regions are subject to expansion or contraction when single-stranded DNA becomes exposed, allowing repetitive sequences to form secondary structures (i.e., DNA hairpins), particularly during replication, transcription, and DNA repair (Pearson et al. 2005).
Single nucleotide polymorphisms (SNPs), SNP haplotypes, repetitive sequences, whether stable or subject to expansion or contraction, appear in a new light, as respective nucleosomes involved may vary in strength and/or position.
Consistent with these results, in the current study we have shown that anti-TSP1 strategies not only reduced fibroblast contractility but also decreased ERK activation in fibroblasts subjected to ECM contraction and mechanical loading.
Moreover, reverse transcription (RT -PCR analysis of mRT -PCRtranalysisof fibroblasts subjected to ECmRNAstraction rextractedhat the TSP1 mRNA levels were altered in a manner paralleling our TSP1 protein analyses.
We conclude that the region of suppressed recombination in the mat chromosomes has likely been subjected to independent contraction and/or expansion during the evolutionary history of the N. tetrasperma species complex.
Single muscle fibers from mdx mice were loaded with a Ca2+ indicator and subjected to stretched contractions, as described previously [18].
