Tumorigenesis analysis and Hisptopathological images

neoplasm

increased incidence of tumors by UV-induction ( J:88125 )

• skin tumorigenesis is enhanced after exposure to UV light but not after exposure to DMBA

• tumors develop earlier, proceed at a greater rate and mice develop more tumors

cellular

decreased cellular sensitivity to ionizing radiation ( J:88125 )

• MEFs are more resistant to killing after UV-irradiation but not after DMBA exposure

growth/size/body

decreased body size ( J:88125 )

• 8 weeks after birth, homozygotes are somewhat smaller

integument

increased sensitivity to skin irradiation ( J:88125 )

• increased incidence of skin tumors after UV-irradiation
