Fluorescence multiplex immunohistochemical analysis of the human breast (Formalin/PFA-fixed paraffin-embedded sections). Panel A : merged staining of anti-B7H4 (ab252438, red; Opal™690), anti-CD10 (ab255609, gray; Opal™520) and anti-FABP4 (ab92501, cyan; Opal™570) on human breast. Panel B : anti-B7H4 stained on glandular lumens. Panel C : anti-CD10 stained on myoepithelial cells. Panel D : anti-FABP4 stained on adipocytes. Opal Polymer HRP Ms + Rb was used as a secondary antibody. The section was incubated in three rounds of staining : in the order of ab252438 at 1/100 dilution (4.69 μg/ml), ab255609 at 1/1000 dilution (0.615 μg/ml) and ab92501 at 1/10000 dilution (0.047 μg/ml) for 30 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system. The immunostaining was performed on a Leica Biosystems BOND® RX instrument with an Opal™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins. DAPI (blue) was used as a nuclear counter stain. This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab92501).

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Fatty acid-binding protein 4 (FABP4) also known as aP2 is a member of the fatty acid-binding protein family. It predominantly exists in adipocytes and macrophages serving an important role in lipid metabolism and transport. FABP4 facilitates the binding and transport of long-chain fatty acids and other hydrophobic molecules within cells. The molecular weight of FABP4 is approximately 14-15 kDa. It exhibits high expression levels in adipose tissue and is inducible in macrophages under certain conditions.
Biological function summary

This protein participates in the regulation of lipid homeostasis and energy metabolism. FABP4 is part of the lipid-binding protein family that helps maintain fatty acid equilibrium within cells. By controlling the transport and signaling of lipids FABP4 impacts lipid storage insulin sensitivity and inflammation processes. Its activity is not confined to a specific multimeric complex yet it interacts with other proteins to exert its functions contributing to significant metabolic pathways in the body.

Pathways

FABP4 plays essential roles in the regulation of metabolic and inflammatory signaling pathways. It is intricately involved in the peroxisome proliferator-activated receptor gamma (PPARγ) pathway where it modulates adipose tissue development and glucose metabolism. In addition FABP4 has connections with the c-Jun N-terminal kinase (JNK) signaling pathway influencing stress and inflammatory responses. Interactions with these pathways place FABP4 at a link with proteins like PPARγ and JNK essential for cellular metabolic balance and responses to metabolic stress.

Researchers connect FABP4 to conditions such as obesity and type 2 diabetes. Its expression levels correlate with insulin resistance and metabolic syndrome making it a target of interest in these metabolic disorders. FABP4 interacts with other proteins like adiponectin which is important in modulating glucose levels and fatty acid breakdown. Understanding FABP4's role in these pathways can facilitate the development of therapeutic strategies aimed at targeting metabolic dysfunctions associated with obesity and diabetes.
