Extracellular signal-regulated kinase 3 (ERK3) is an atypical protein kinase of the mitogen-activated protein kinase (MAPK) family. In comparison to well-investigated ERK1/2 (classical) MAPKs, much less has been discovered about ERK3 signaling and its cellular functions. Recent studies have shown that ERK3 is overexpressed in various types of cancers such as lung cancer and breast cancer and that ERK3 promotes cancer cell migration and invasion. How ERK3 regulates cancer cell motility and invasiveness, however, is still largely unknown. RhoGTPases, including Rho, Cdc42 and Rac1, play critical roles in regulating cell motility and invasiveness through activating downstream effectors such as ...

The p53 protein is a tumor suppressor protein that is mutated or non-functional in nearly all cancers. The Mdm2 protein has the ability to functionally inactivate p53 and these two proteins have been studied extensively in the context of cellular proliferation. In this study, expression of the murine double minute 2 (mdm2) gene was examined in the mouse NIH3T3L1 cell line. Under the proper conditions, the immortalized NIH3T3L1 cells have the ability to differentiate from fibroblasts to adipocytes (Green et al., 1975). This well characterized cell line provides an excellent model to study mdm2 in differentiation. While evaluating the regulation ...
