    Immunofluorescence results showing effect of simvastatin on GJIC targeting Cx37, Cx40 and Cx43. Cx37 (A) and Cx40 (B) expression was downregulated in gap junctions of HUVECs treated with TNF-α relative to the control group. Treatment of HUVECs with simvastatin upregulated Cx37 and Cx40 expression. Similarly, HUVECs treated with TNF-α exhibited Cx43 up-regulation (C) although simvastatin reversed this phenomenon.

    Differential expression of Cx37, Cx40 and Cx43 mRNAs in HUVECs across groups. Cx37 and Cx40 had a 2-fold downregulation, whereas Cx43 was upregulated relative to the control group. Cx37 and Cx40 were significantly upregulated in HUVECs treated with TNF-α in combination with simvastatin relative to those treated with TNF-α alone. Cx43 was significantly downregulated. Data presented are means ± SEM, n = 6, ** P < 0.01 versus only TNF-α treatment group.

    Article Snippet: Primary antibodies used for immunostaining were as follows: rabbit antibodies to Cx37 ( Simon et al., 2006 ), Cx43 (C6219, Sigma), Prox1 (11–002, AngioBio; ab11941, Abcam), pHH3 (06–570, Millipore); rat antibodies to CD31 (550274, BD Biosciences); goat antibodies to Foxc2 (ab5060, Abcam), Vefgr3 (AF743, R&D Systems).

    Techniques: Immunolabeling, Quantitation Assay

    Evans blue dye (EBD) lymphangiography of WT, Foxc2 +/−, Foxc2 +/−Cx37 +/−, and Foxc2 +/−Cx43 +/− adult mice. EBD drainage patterns in the ear (A–D), abdominal cavity (E–H), and thoracic cavity (I–L). EBD readily filled the lymphatics of ear (injection site denoted by the asterisk), the lumbar lymph nodes (E-H, labeled “LN”), and thoracic duct (denoted by arrows in I-L) of WT, Foxc2 +/−, Foxc2 +/−Cx37 +/−, and Foxc2 +/−Cx43 +/− mice. No obstructions or reflux of EBD were found in the areas examined.
