Does cumulus-associated alpha2-macroglobulin derivative retain proconceptive glycodelin-C in the human cumulus matrix?
The hyaluronic acid-GIP complex formed in the cumulus matrix retains and concentrates glycodelin-C in the cumulus matrix for displacing sperm-bound glycodelin-A and -F and stimulating the zona binding activity of the spermatozoa traversing through the cumulus mass.
Our results suggest that AEBP1 negatively regulates adipose tissue PTEN levels, in conjunction with its role in proliferation and differentiation of pre-adipocytes, as a key functional role in modulation of in vivo adiposity.
