Correlated evolution is commonly observed when traits are functionally related. It is hypothesized that proteins involved in a pathway are likely to evolve in a correlated fashion, and coevolving gene families tend to undergo complementary gains and losses. Accordingly, gene copy numbers tend to show parallel changes during the evolution of coevolving gene families.
To test and verify this ... more |

Mustelidae, as the largest and most-diverse family of order Carnivora, comprises eight subfamilies. Phylogenetic relationships among these Mustelidae subfamilies remain argumentative subjects in recent years due to Mustelids’ rapid evolutionary radiation and recent speciation.
In order to clarify Mustelidae subfamilies’ phylogenetic relationships, the research group headed by academician ... more |

| Lectins, which can specifically recognize sugar molecules and bind the glycosylated nasal mucosa, have been introduced into bioadhesive delivery systems to improve drug absorption on nasal mucosa. Odorranalectin (OL), with a molecular weight of only 1700 Da, was recently identified as the smallest lectin with much less immunogenicity than other members of the lectin family by the research team ... more |

Mucosa is the body’s first barrier with the outside world. People alway take a large number of alcohol, pepper and other stimuli, or long-term use of non-steroidal anti-inflammatory analgesic drugs (such as aspirin), that can cause stomach pain, diarrhea and mouth sores and other symptoms of the disease. That is because the gastrointestinal mucosal hurt. Vertebrates are widely distributed... more |

βγ-CAT, a non-lens betagamma-crystallin and trefoil factor complex, is found to induce calcium-dependent platelet apoptosis, suggested the research team headed by ZHANG Yun from Kunming Institute of Zoology, Chinese Academy of Sciences (KIZ, CAS).
βγ-CAT dots the skin secretions of mammals, whose mechanism and function, however, remain unknown to scientists. The research team of KIZ bla... more |
