doi: 10.1038/s41467-025-65259-0
Figure Lengend Snippet: a PAI-1 in plasma from AML patients ( n = 39) was measured using a commercial assay kit, followed by Pearson correlation analysis with corresponding plasma lactate. b Immunofluorescence staining was performed to evaluate the expression of H3K18la, and PAI-1 in the IVC tissues of thrombus-forming segment. (CD31, an endothelial cell marker; scale bar=50 μm; n = 6 mice per group). c Conditioned media (CM) from NB4 and MOLM13 cells cultured for 12 or 24 hours were co-cultured with HUVECs. Pan-Kla and H3K18la levels in HUVECs were analyzed by Western blot ( n = 3 biological replicates). d, e mRNA and protein expression of PAI-1 in HUVECs co-cultured with conditioned media from AML cell lines were assessed by qPCR and Western blot, respectively ( n = 3 biological replicates). f Plasmin generation in HUVECs co-cultured with conditioned media from AML cell lines was continuously monitored at 405 nm ( n = 3 biological replicates). g Fibrinolysis rate was monitored at 405 nm after co-culture of HUVECs with conditioned medium from AML cell lines, dashed line represents 50% lysis of the clot ( n = 3 biological replicates). h, i HUVECs were transfected with siRNA targeting MCT1 (si MCT1 ), and MCT1 knockdown efficiency was assessed by qPCR and Western blot ( n = 3 biological replicates). j si MCT1 HUVECs were co-cultured with conditioned media from THP-1 cells, and Pan-Kla and H3K18la levels were analyzed by Western blot ( n = 3 biological replicates). k , l si MCT1 HUVECs were co-cultured with conditioned media from THP-1 cells, and PAI-1 mRNA and protein expression were assessed by qPCR and Western blot, respectively ( n = 3 biological replicates). m Plasmin generation was continuously monitored at 405 nm ( n = 3 biological replicates). n Fibrinolysis rate was continuously monitored at 405 nm after co-culture of THP-1-conditioned medium with HUVECs, dashed line represents 50% lysis of the clot ( n = 3 biological replicates). siNC, negative control. Data were analyzed by Pearson correlation analysis ( a ), two-tailed Student’s t test ( d , h , k ), and two-way ANOVA with Sidak’s multiple comparisons test ( f , g , m , n ). Data are presented as mean ± SD. Source data are provided as a Source Data file.
Article Snippet: Human umbilical vein endothelial cells (HUVEC) were cultured in HUVEC cell-specific medium (Procell) and used within 5 passages.
