CTSW and non-small cell lung carcinoma: In research done by Song and colleagues, the expression of CTSF in non-small cell lung cancer was evaluated, and downregulated levels of CTST were observed in NSCLC samples despite normal tissues and good prognosis of NSCLC being correlated with high expression of CTSF. Besides using GeneMANIA, the gene–gene interaction network was established for CTSF and showed that CTSF had a similar function as CTSW genes43.
