Introduction

Adult hamster

These rodents belonging to the subfamily Cricetinae. Sexual maturity occurs at about 4 to 6 weeks and hamsters are seasonal breeders (April to October in the northern hemisphere) with several litters of 1 to 13 pups after a gestation period of between 16 to 23 days. The Chinese hamster (Cricetulus griseus) ovary (CHO) cells have been used widely in research as a host for protein production.

Some Recent Findings

  • Hyperthermia induces upregulation of Connexin43 in the golden hamster neural tube[1] "During early embryonic development, maternal exposure to hyperthermia induces neural tube defects (NTDs). Connexins are essential for the formation of gap junctions and Connexin43 (Cx43) is crucially involved in neural tube development. ...Our data provide the first evidence that hyperthermia induces upregulation of Cx43 in the golden hamster neural tube. NTDs caused by hyperthermia may be intimately related with the overexpression of Cx43."
  • Biosynthesis of hamster zona pellucida is restricted to the oocyte[2] "We recently described the expression of four ZP proteins in the hamster ovary. By means of the complete set of the hamster ZP cDNAs, we undertook the study of the origin and expression pattern of the four ZP genes. In the present work, the expression of ZP1, ZP2, ZP3 and ZP4 is carefully analyzed by in situ hybridization (ISH) in hamster ovaries. Our data suggest that the four hamster ZP genes are expressed in a coordinate and oocyte-specific manner during folliculogenesis. Furthermore, this expression is maximal during the first stages of the oocyte development and declines in oocytes from later development stages, particularly within large antral follicles."
