(A) SPARCL1 mRNA expression in microdissected pancreatic ductal cells. Microarray analysis for the mRNA levels of SPARCL1 from NP tissues (n = 13), NP ducts (n = 3), ducts from CP tissues (n = 5), and cancer cells (n = 6). Values represent arbitrary units normalized to housekeeping genes [30] and NP tissues (mean set to 100). (B) SPARCL1 mRNA expression in bulk pancreatic tissues. Microarray analysis for the mRNA levels of SPARCL1 from NP tissues (n = 13), CP (n = 10), PDAC tissues (n = 10), and liver metastases of pancreatic cancer (n = 10). Values represent arbitrary units normalized to housekeeping genes [30] and NP tissues (mean set to 100). Horizontal bars represent mean values.
