Abstract

Metallothionein cDNA was detected in the retinas of cynomolgus monkeys (Macaca fascicularis) using RT-PCR. Sequencing of this cDNA showed almost a hundred percent sequence similarity with metallothionein cDNA from rhesus monkey kidneys. There was only a single base substitution (ACC - ACU) for Thr 14. A comparison of the amino acid sequence also showed a high percentage similarity with metallothionein class II isolated from other sources. Previous reports of several laboratories have implicated the induction of metallothionein synthesis as a response to oxidative stress which in turn is due to solar bombardment and phagocytosis of photoreceptors, particularly rod outer segments, by retinal pigment epithelium.
