In CRS male mice, p21CIP1/WAF1 mRNA expression levels correlated negatively with weight gain, p16INK4a protein expression levels correlated positively with greater sucrose consumption and correlated negatively with coat state, and p21Waf1/Cip1 protein expression levels correlated positively with RA SZ and correlated negatively with sucrose consumption. The gene discussed is CDKN1A; the disease is congenital rubella syndrome.
