Figure Lengend Snippet: The expression of EN2 in HPNE, pancreatic cancer cell lines, and pancreatic CSCs. (A), Protein expression of EN2 in HPNE, pancreatic cancer cell lines, and pancreatic CSCs. Crude proteins were isolated, and EN2 expression was measured by Western blot analysis. β‐Actin was used as a loading control. (B), Expression of EN2 mRNA in HPNE, pancreatic cancer cell lines, and pancreatic CSCs. RNA was isolated, and EN2 expression was measured by q‐RT‐PCR. GAPDH was used as an internal control. Data represent mean ( n = 4) ± SD. *, # and % = significantly different from HPNE ( p < 0.05). (C), Expression of EN2. Immunocytochemistry was performed to examine EN2 expression in HPNE, PANC‐1, and AsPC‐1 cells.

Figure Lengend Snippet: Overexpression of EN2 in HPNE cells induces cellular transformation and stemness. (A and B) HPNE cells were stably transduced with lentiviral particles expressing either empty vector or EN2 cDNA. EN2 expression was measured by immunocytochemistry and qRT‐PCR. Blue colour = nuclei; Green colour = EN2. Data represent mean ( n = 4) ± SD. * = significantly different from HPNE/Empty Vector group ( p < 0.05). (C), Spheroid formation in suspension. Spheroid formation of HPNE/Empty Vector and HPNE/EN2 cDNA cells was measured. Spheroids in suspensions were photographed (left) and counted (right). Data represent mean ( n = 4) ± SD. # = significantly different between groups ( p < 0.05). (D), Expression of stem cell markers. RNA was isolated, and expression of stem cell markers (CD24, CD44, CD133 and LGR5) was measured by qRT‐PCR. GAPDH was used as an internal control. Data represent mean ( n = 4) ± SD. * = significantly different from HPNE/Empty Vector group ( p < 0.05). Gene expression of Empty Vector was normalised to 1. (E), Expression of pluripotency‐maintaining factors. RNA was isolated, and the expression of pluripotency‐maintaining factors (Oct4, Sox2, cMyc and KLF4) was measured by qRT‐PCR analysis. GAPDH was used as an internal control. Data represent mean ( n = 4) ± SD. * = significantly different from HPNE/Empty Vector group ( p < 0.05). Gene expression of Empty Vector was normalised to 1.

Figure Lengend Snippet: Overexpression of EN2 in HPNE cells enhances cell motility and modulates expression of EMT‐related genes. (A) Cell Motility. HPNE cells were stably transduced with lentiviral particles expressing either empty vector or EN2 cDNA. (B) Expression of EMT‐related genes. RNA was isolated, and the EMT‐related genes (E‐cadherin, N‐cadherin, Snail, Slug, and Zeb1) were measured by qRT‐PCR analysis. GAPDH was used as an internal control. Data represent mean ( n = 4) ± SD. * = significantly different from HPNE/Empty Vector group ( p < 0.05). Gene expression of Empty Vector was normalised to 1.

Article Title: MiR-641 targets TMEFF2/MEK/PI3K to promote stem cell characteristics of pancreatic cancer cells

doi: 10.1007/s12672-026-04584-2

Figure Lengend Snippet: The expression of miR-641 in pancreatic cancer. A The expression of miR-641 in 60 paired pancreatic cancer tumor tissue and non-tumor tissue was explored by qPCR. B The expression of miR-641 in different stages of pancreatic carcinoma patients. * P < 0.05, ** P < 0.01. C Kaplan–Meier analysis showed that higher expression of miR-641 predicted poor survival rate of pancreatic cancer patients. D The expression of miR-641 in pancreatic cancer cells (SW1990, CFPAC-1, BxPC-3 and PANC-1) and normal human pancreatic ductal epithelial cells (HPDE6-C7) was examined by qRT-PCR. ** P < 0.01 vs. HPDE6-C7. Data was shown as mean ± SD
