C1qA and C1qC gene expression is upregulated in photoreceptor cells of aging DBA/2J mice.

(A) Agarose gels showing PCR fragments that represent the gene expression of C1qA, C1qB and C1qC in the retinae of 2 and 6 months old DBA/2J and C57BL/6 control mice. (B) The expression of C1qA, C1qB and C1qC in photoreceptor cells of 2, 6, and 10 months old DBA/2J mice and age-matched C57BL/6 control mice was compared with PCR. For each age, cDNA obtained from three animals was subjected to triplicate PCR amplifications (n = 9). Statistically significant differences are indicated by asterisks (* p<0.05; ** p<0.01).
