Young Athletes’ ACTN and PPAR Genes Help Performance, Too

The presence of Actin (ACTN) and Peroxisome proliferator-activated receptor (PPAR) gene families is frequently mentioned in literature reports and news articles. This extends to young athletes as well: Boys with ACTN3 RR genotype tended to swim faster (25m and 100m) (34) regardless of training status. The R allele was also associated with better 40m sprint performance … Continue reading Young Athletes’ ACTN and PPAR Genes Help Performance, Too

957 Genes Associated with Aging

Aging, oxygen muscles & mitochondria...all related. In one published analysis, genes regulating oxygen consumption are closely tied with aging. Genetics geeks (us included) will appreciate the laboriousness of relabeling genetic information so that it is useful. Table 2 shows a list of genes associated with aging from research at Skåne University and Lund University. Here is one … Continue reading 957 Genes Associated with Aging

Actins: the “sprinter” gene family has multiple isoforms

If you have had any genetic tests, you've probably come across the "sprinter gene", or Actin. Here is a paper showing that there are multiple actins, each with small differences in amino acid structure. These include cariac-, smooth-, and muscle- isoforms. Interestingly, small differences can lead to different function: Although actin is often thought of … Continue reading Actins: the “sprinter” gene family has multiple isoforms
