DUSP6 protein, human
This enzyme functions as a negative regulator of the MAPK/ERK (Mitogen-Activated Protein Kinase/Extracellular Signal-Regulated Kinase) signaling cascade, which is involved in cellular processes such as proliferation, differentiation, and survival.
DUSP6 specifically dephosphorylates and inactivates ERK1 and ERK2, thereby modulating the intensity and duration of ERK-mediated signaling.
Dysregulation of DUSP6 has been implicated in various disease conditions, including cancer, neurological disorders, and metabolic diseases.
Understanding the functions and regulation of DUSP6 is crucial for developing targeted therapies and improving disease management.

Example 1
Cells were treated with the indicated compounds for 7 hours before lysis with Buffer RLT (QIAGEN, Hilden, Germany) containing 1% β-mercaptoethanol. Total RNA was isolated using the Rneasy Plus Mini kit (QIAGEN, Hilden, Germany) according to the manufacturer's instructions. First-strand cDNA was synthesized using the SuperScript VILO Master Mix (Thermo Fisher Scientific, Waltham, MA) according to the manufacturer's instructions. Real-time qPCR was run on ViiA 7 Real Time PCR System (Thermo Fisher Scientific). For qRT-PCR, the expression of the reference gene glucuronidase beta (GUSB) was used to normalize expression of the target genes DUSP6, SPRY4, and glycogen synthase kinase 3 beta (GSK3B). Replicate qRT-PCR reactions were analyzed for each sample, and QuantStudio Real-Time PCR software (Life Technologies, Carlsbad, CA) normalized the average expression of DUSP6, SPRY4, or GSK3B to the average expression of the reference gene GUSB in each sample.
cDNA was prepared from samples by using a cDNA Synthesis Kit (Invitrogen, Carlsbad, California, United States). Quantitative RT-PCR analysis was performed with a LightCycler 480 II PCR platform (Roche) with FastStart Essential DNA Probes Master reaction mix for PCR (Roche) or SYBR Green I Master reagents (Roche).
Gene expression levels were normalized to that of the β-actin gene Actb. The following primer sequences were used for PCR with FastStart Essential DNA Probes Master for mouse: Cxcl1 forward, 5′-gactccagccacactccaac-3´; Cxcl1 reverse, 5′-tgacagcgcagctcattg-3′; Cxcl2 forward, 5′-aaaatcatccaaaagatactgaacaa-3′; Cxcl2 reverse, 5′-ctttggttcttccgttgagg-3′; Hbegf forward, 5′-tcttcttgtcatcgtgggact-3′; Hbegf reverse, cacgcccaacttcactttct-3′; Actb forward, 5′-aaggccaaccgtgaaaagat-3′; and Actb reverse, 5′-gtggtacgaccagaggcatac-3′. The following primer sequences were used for PCR with SYBR Green I Master reagents for human: DUSP1 forward, 5′-agtaccccactctacgatcagg-3′; DUSP1 reverse, 5′-gaagcgtgatacgcactgc-3′; DUSP6 forward, 5′-gaaatggcgatcagcaagacg-3′; DUSP6 reverse, 5′-cgacgactcgtatagctcctg-3′; MKK3 forward, 5′-gactcccggaccttcatcac-3′; MKK3 reverse, 5′-ggcccagttctgagatggt-3′; MKK4 forward, 5′-tgcagggtaaacgcaaagca-3′; MKK4 reverse, 5′-ctcctgtaggattgggattcaga-3′; ACTB forward, 5′- catgtacgttgctatccaggc-3′; and ACTB reverse, 5′-ctccttaatgtcacgcacgat -3´.
