This study found that bovine slick mutations may enhance heat stress responses in mice but do not lead to the expected hair phenotype changes.
July 2026 in “Frontiers in Endocrinology” This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.

June 2020 in “Animal genetics” In this study, researchers identified genetic variants in the PCCA and PRLR genes that are significantly associated with hair coat length in Brangus heifers, potentially contributing to more thermotolerant cattle.
August 2018 in “Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign)” This research observed that chronological age, rather than hearing loss, primarily affects the auditory cortex in aging, and found that brain aging in PolG mice mirrored that of wild-type counterparts, suggesting differential tissue sensitivity to mitochondrial dysfunction.
