"Hair follicle-specific keratin genes consisted of 9 hair follicle-specific epithelial keratin genes (K71-K75, K25-K28) and 17 hair keratins (K31-K40, K81-K86) expressed in hair follicle and hair which could directly affect hair growth." |

| Methodology & Validation |
"We first identified α-keratin gene repertoires in the cow (Bos taurus) (coverage 7×,Btau_4.6.1) [...] taking all the known α-keratin gene sequences of human as queries using BLASTN and TBLASTN algorithm. [...] The putative α-keratin genes in the cow were then taken as queries to explore the α-keratin multigene family in the genome of 11 marine mammals, including [...] Weddell seal (Leptonychotes weddellii, coverage 82×, LepWed_1.0, NCBI)." |

"Similar evolution pattern of α-keratin gene repertoire in the pinnipeds, polar bear and their terrestrial relatives is likely due to abundant hair to keep warm when they went ashore to mate, give birth, molt or escape from predators." |

"By contrast, [α-keratin] gene repertoires in the pinnipeds (56) and polar bear (58) were similar to that of panda (58)." |
