Immunofluorescence staining was performed as previously described [16 (link)]. The primary antibodies used were PPAR- γ (Cell Signaling Technology) and SREBP-1 (Santa Cruz Biotechnology, Santa Cruz, CA, USA). The secondary antibodies used were Alexa Fluor 488 and/or Alexa Fluor 594.
The SZ95 cells were fixed with 10% formalin for 15 min at room temperature. The cells were subsequently treated with 0.1% Triton X-100 in PBS for 5 min to permeabilize them. Then, the cells were blocked at room temperature for 30 min and incubated with primary antibody against SREBP-1 and PPAR-γ at 37 °C for 1 h. For double staining, a reaction with Alexa Fluor 488 phalloidin (Thermo Fisher Scientific, Waltham, MA, USA) was performed at room temperature for 1 h. The nuclei were stained with 4′,6-diamidino-2-phenylindole (DAPI) for 5 min at 37 °C. The slides were mounted using VECTASHIELD Mounting Medium (VECTOR Laboratories, Burlingame, CA, USA).

At day one after birth, adipose tissue was collected from the pups that were culled to standardize the litter size. Newborns were decapitated and inguinal (subcutaneous) adipose tissue was pooled from 4 males per litter. At 9 months of age, retroperitoneal (visceral) adipose tissue, which is associated with obesity and insulin resistance21 (link),22 (link) was collected and samples frozen in liquid nitrogen and stored at −80°C till protein analysis. To control for litter effects in the adult studies, one male was studied from each of the litters. Thus when n = 6, it represents one male from each of 6 different litters in Control, IUGR and Mat-OB groups.
Protein was extracted in radioimmuno precipitation assay (RIPA) buffer that contained protease inhibitors (HALT cocktail, Pierce). Supernatant protein concentration was determined by BCA solution (PIERCE, Rockford, IL). Protein expression was determined by Western Blotting, as previously described.15 (link) Antibodies were obtained from Santa Cruz, CA unless otherwise specified and the band density was analyzed as indicated: PPARγ (57 kDa; Thermo Scientific, Rockford, IL), C/EBPα (42 kDa), SREBP1c (125 kDa), FAS (270 kDa), hormone sensitive lipase (84 kDa), SIRT1 (120 kDa), NCoR (270 kDa), SMRT (160 kDa), SRC1 (160 kDa), TIF2 (158 kDa) and β-actin (Sigma, A-5441; 40 kDa).

Briefly, homogenization buffer was added to tissues which were then homogenized on ice, centrifuged, and the supernatant carefully removed. Basing on Bradford protein quantification, the 50 μg protein lysate was electrophoretically fractionated through a 12% SDS-polyacrylamide gel and electrotransferred onto a polyvinylidene difluoride (PVDF) membrane (Amersham, Piscataway, NJ, USA). The blots were soaked in blocking buffer for one hour at room temperature to block non-specific protein-binding sites. The primary antibodies for BMAL1 (EMD Millipore, Billerica, MA, USA; 1/2500), PPARγ (Thermo Fisher Scientific, Waltham, MA, USA; 1/4000) and β-Actin (EMD Millipore; 1/20000) were diluted in TBST buffer according to the titer of the antibodies. The horseradish peroxidase-conjugated secondary antibodies (EMD Millipore; 1/4000) were diluted in TBST. Detection of the immunoreactive components on the blots were performed by using the ECL (Santa Cruz, CA, USA) Western Blotting detection reagent depending on the sensitivity of the antibodies.

For total protein isolation of cultured HBMECs, cells were washed twice with PBS prior to adding a lysis buffer. A plasma membrane protein extraction kit (Abcam, Cambridge, MA, USA) was used for sample collection. Protein samples (plasma membrane proteins or nuclear extractions) were equally separated in a 4%–20% NuPage gel prior to being transferred to nitrocellulose membranes. Primary antibodies used for overnight membrane incubation at 4 °C are as follows: PPARγ (1:1000, Thermo Fisher, Rockford, IL, USA), ZO-1 (1:1000, Cell Signaling, Beverly, MA, USA), VE-cadherin (1:1000, Enzo Life Sciences, Farmingdale, NY, USA), Na-K-ATPase (1:1000, Abcam), and Histone H3 (1:1000, Cell Signaling).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
