Our experimental results (summarized in Figure 3) on the 8505C (anaplastic, 3A & 3C) and BCPAP (papillary, 3B & 3D) human thyroid cancer cell lines stably transfected with DDX19B, NEMP1, PANK2 or UBALD1 (characteristics in Figure 1) indicate that:(6)GCHNEMP1(BCPAP)>GCHNEMP1(8505C)⇒WPRNEMP1(BCPAP)>WPRNEMP1(8505C)GCHPANK2(BCPAP)>GCHPANK2(8505C)⇒WPRPANK2(BCPAP)>WPRPANK2(8505C)GCHDDX19B(BCPAP)<GCHDDX19B(8505C)⇒WPRDDX19B(BCPAP)<WPRDDX19B(8505C)GCHUBALD1(BCPAP)<GCHUBALD1(8505C)⇒WPRUBALD1(BCPAP)<WPRUBALD1(8505C). This evidence concerns the gene PANK2 and thyroid cancer.
