TABLE 3

Differential OATP protein expression in cancer tissues

See the text for references for this table.

Protein	Malignant Tissue Distribution^{^a}
OATP1A2	Increased expression: breast, pancreas, bone, some lung cancer cell lines
	Decreased expression: colon, some lung cell lines
OATP1B1	Increased expression: breast, pancreas, prostate, ovary, lung, colon
	Decreased expression: liver
OATP1B3	Increased expression: colon, pancreas, lung, breast, prostate, ovary, lung, stomach, gallbladder
	Decreased expression: liver
OATP2B1	Increased expression: lung (conflicting evidence), breast, colon, bone
	Decreased expression: none reported

↵^a Increased and decreased refer to expression of the transporter in malignant tissue compared with normal tissue of the same type.
