Total cell RNA extracted, separately, from three human cancer cell lines, HeLa, CaSki and SiHa (for human SRSF3) and mouse epithelial keratinocytes (MEK) (for mouse Srsf3) was used for 5′ RACE in the presence of a human SRSF3-specific antisense primer, oVM238 or a mouse Srsf3-specific antisense primer, oMA28. The gene discussed is SRSF3; the disease is cancer.
