Molecular evolution of antioxidant and hypoxia response in long-lived, cancer-resistant blind mole rats: The Nrf2-Keap1 pathway.
2015
The Nrf2-Keap1 pathway is crucial for the cellular antioxidant and hypoxia response in vertebrates. Deciphering its modifications in hypoxia-adapted animals will help understand its functionality under environmental stress and possibly allow for knowledge transfer into biomedical research. The blind mole rat Spalax, a long-lived cancer-resistant rodent, lives in burrows underground and is adapted to severely hypoxic conditions. Here we have conducted a bioinformatical survey of Spalax core genes from the Nrf2-Keap1 pathway on the coding sequence level in comparison to other hypoxia-tolerant and -sensitive rodents. We find strong sequence conservation across all genes, illustrating the pathw…
Genome-wide adaptive complexes to underground stresses in blind mole rats Spalax
2014
The blind mole rat (BMR), Spalax galili, is an excellent model for studying mammalian adaptation to life underground and medical applications. The BMR spends its entire life underground, protecting itself from predators and climatic fluctuations while challenging it with multiple stressors such as darkness, hypoxia, hypercapnia, energetics and high pathonecity. Here we sequence and analyse the BMR genome and transcriptome, highlighting the possible genomic adaptive responses to the underground stressors. Our results show high rates of RNA/DNA editing, reduced chromosome rearrangements, an over-representation of short interspersed elements (SINEs) probably linked to hypoxia tolerance, degene…
