MYLKP1 and leukemia: Moreover, MYLKP1 and smMLCK exhibit differential transcriptional profiling with MYLKP1 strongly expressed in cancer cell lines (cervix, leukemia, uterus, colon) and tissues (colon, lymph node, vulva, bladder carcinoma), whereas smMLCK is highly expressed in non-neoplastic cells (bone marrow stem, uterine fibroblast, airway smooth muscle) and tissues (brain, breast, cervix, colon, liver, uterus, vein), tissues where MYLKP1 expression is virtually absent.
