CRYAB and neoplasm: Using this constitutive overexpression mouse model of Cryab, we monitored a cohort of wild type mice (hereafter referred to as CryabWt, n = 40) as a control group to compare with homozygous transgenic mice overexpressing αB-Crystallin (CryabTg, n = 40: 23 Females, 17 Males) over time for spontaneous tumor formation.
