Cell viability was determined via MTT assay, while intracellular lipid droplet (LD) accumulation was evaluated using Oil Red O staining. Transcriptional alterations of canonical WNT\/\u03b2\u2010catenin cascade genes (WNT, CTNNB1, GSK\u20103\u03b2, TCF, LEF, Axin1, and Axin2) were analyzed by RT\u2010qPCR. Protein expression levels of WNT, \u03b2\u2010catenin, and Glypican\u20103 (GPC3) were evaluated to assess pathway activation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Both fatty acids induced dose\u2010dependent cytotoxicity and intracellular lipid accumulation, with the combined PA\/OA treatment provoking the highest LD content. At the molecular level, palmitate predominantly activated the canonical cascade, significantly upregulating WNT, CTNNB1, TCF, and Axin2 mRNA, alongside elevated WNT, \u03b2\u2010catenin, and GPC3 protein levels. Conversely, oleate selectively upregulated LEF and GSK\u20103\u03b2 without coordinated canonical cascade activation, maintaining lower WNT and GPC3 protein expressions. Interestingly, co\u2010treatment with PA\/OA yielded intermediate molecular responses, partially attenuating palmitate\u2010induced activation of WNT and Axin2, and facilitating a partial recovery of Axin1 expression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PA and OA differentially modulated WNT\/\u03b2\u2010catenin pathway\u2010associated responses in lipid\u2010loaded HepG2 cells. PA elicited a broader response involving WNT, CTNNB1, TCF, Axin2, WNT, and \u03b2\u2010catenin, whereas OA produced a more selective response. Their combination partially attenuated PA\u2010associated changes, highlighting fatty acid composition as a potential determinant of cellular responses to lipotoxic stress.<\/jats:p>\n
