For example, lncRNA ZFAS1 could enhance PTX resistance of SGC7901 gastric cancer cells by altering the expressions of EMT markers (E-cadherin, N-cadherin, and vimentin) and cell cycle related proteins (cyclin D1, cyclin E and cyclin B1), as well as the Wnt/β-catenin signaling [173]. This evidence concerns the gene CCND1 and gastric cancer.
