Naked mole-rat has become the first mammalian to have waived infection-resistant proteins

sarah JonasResearch Results

Scientists have found that the naked mole-rat — an underground rodent that lives up to 40 years — has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious diseases. The findings indicate that the naked mole-rat’s immune system has significantly realigned and is using other — CD1-independent — molecular mechanisms. The results of the studies, supported by the Grants of Presidential program of the Russian Science Fund (RSF), were published in the Biology Direct magazine.

Ripe for discovery: unraveling the genetic switches of pear maturation

sarah JonasResearch Results

A new study has revealed a key homeodomain transcription factor, PbHB.G7.2, that plays a crucial role in ethylene biosynthesis during pear fruit ripening. By binding to the promoter of the ethylene biosynthetic gene PbACS1b, PbHB.G7.2 enhances ethylene production, significantly impacting the ripening process.
