Figure Lengend Snippet: LPL regulates tumour progression in PTC cell lines. A , B The total protein and mRNA levels of LPL in K1 and BCPAP cells transfected with si-LPL1 or si-LPL2 were detected by Western blot ( A ) and RT-qPCR ( B ) ( n = 3). C CCK8 assay results showing that the downregulation of LPL can inhibit the proliferation of TC cells ( n = 3). D Colony formation assays revealed changes in the proliferative capacity of si-LPL- or si-NC- transfected PTC cells ( n = 3). The downregulation of LPL can inhibit the colony formation of PTC cells. E TUNEL staining revealed that the downregulation of LPL promoted the apoptosis of PTC cells ( n = 5). * P < 0.05, ** P < 0.01, *** P < 0.001 vs. si-nc.

Figure Lengend Snippet: FASN regulates tumour progression in PTC cell lines. A The protein levels of FASN in PTC (K1 and BCPAP) cells and normal thyroid cells (N-3-1). FASN is highly expressed in PTC cell lines. B After C75, a specific FASN inhibitor, was used, Western blotting analysis confirmed the effective downregulation of FASN protein expression in PTC cells. C CCK8 assay results demonstrated that suppression of FASN effectively inhibited the proliferation of PTC cells ( n = 3). D Colony formation assay results revealed that suppression of FASN can inhibit the colony formation of PTC cells ( n = 3). E TUNEL staining revealed that suppression of FASN promoted the apoptosis of PTC cells ( n = 5). * P < 0.05, ** P < 0.01, *** P < 0.001 vs. the control.

Figure Lengend Snippet: Combined downregulation of LPL and FASN inhibits PTC cell proliferation and boosts apoptosis. Simultaneous treatment with the pharmacological inhibitor C75 of FASN and siRNA-mediated downregulation of LPL resulted in the suppression of both FASN and LPL expression. A Western blot analysis was conducted to detect the protein levels of LPL in K1 and BCPAP cells following C75 inhibition. These results indicated that C75 had no significant impact on LPL expression. B CCK8 assay results revealed that the combined downregulation of LPL and FASN has a synergistic effect, further inhibiting the proliferation of PTC cells ( n = 3). Statistical analysis revealed significant between-group differences ( P < 0.05) exclusively at the 72-h time point; consequently, the graph presents only these time-specific results. C Colony formation assay results indicated that the simultaneous downregulation of LPL and FASN significantly diminished the clonogenic capacity of PTC cells ( n = 3). E TUNEL staining revealed that the combined downregulation of LPL and FASN further promoted the apoptosis of BCPAP cells ( n = 5). * P < 0.05, ** P < 0.01, *** P < 0.001 vs. si-LPL + C75.
