B-cell lymphoma 2 (Bcl2); NF-kB; the wnt/-catenin pathway [38]; and peroxisome proliferator-activated receptor (PPAR), which plays a key role in adipogenesis and is linked to obesity, insulin-dependent treatment [39], and osteoporosis [38], were discovered to modulate many gene expressions that promote adipogenesis but are also linked to cancer. This evidence concerns the gene BCL2 and cancer.
