Eligibility Criteria
Our laboratory has conducted a pilot study to look at UGT1A expression in both normal and cancer tissue using RT PCR. We have found that in UGT1A6 is the predominant UGT1A enzymes expressed in normal lung and the expression of UGT1A6 enzymes is down regulated in lung cancer (unpublished data). The distribution of UGT1A enzymes in the lung suggests that UGT1A6 may be important in the glucuronidation of inhaled UGT substrates including chemicals from tobacco smoking.
You may qualify if:
