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.

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.
