In another study, researchers have analyzed the genome-wide expression profiles of solid tumor samples by Affymetrix GeneChip hybridization and found that LAPTM4B was significantly upregulated in lung and colorectal cancer samples; Northern blot analysis showed that LAPTM4B was overexpressed in most uterine, breast, and ovarian cancers [13]. The gene discussed is LAPTM4B; the disease is colorectal cancer.
