Abstract:
We examined the chronically hyperproliferative epidermis of the asebia (ab/ab) mouse for circadian rhythms in cell proliferation and in the rate of DNA synthesis, which is related to S phase duration. The curve for the circadian rhythm in cell proliferation for asebia epidermis was suppressed and distorted in comparison to that for BALB/cJ epidermis and in comparison to a composite curve produced by averaging the results from ten other published studies.
