USP15 activates YAP1. 12 / 12
| 12

reach
"Ubiquitin-specific protease 15 (USP15) was reported to promote pulmonary vascular remodeling in PAH by stabilizing YAP1 through the inhibition of the K48-linked ubiquitination of YAP1 ( Table 1 ) [ 16[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"USP15 deficiency inhibited cell proliferation, migration, and YAP1/TAZ signaling in hypoxia-induced hPASMCs."

reach
"Thus, we propose that USP15 might be a novel regulator of YAP1/TAZ signaling during PH progression.Our rescue assay determined that USP15 promoted the proliferation and migration of hypoxia-exposed PASMCs in a YAP1/TAZ-dependent manner."

reach
"USP15 overexpression promoted hPASMC proliferation and migration in a YAP1/TAZ-dependent manner."

reach
"USP15 promotes pulmonary vascular remodeling in pulmonary hypertension in a YAP1/TAZ-dependent manner."

reach
"To further explore whether USP15 mediated hPASMC proliferation and migration in a YAP1/TAZ-dependent manner, we achieved the depletion of YAP1 or TAZ in USP15-overexpressing hPASMCs by corresponding adenovirus infection."

reach
"We, therefore, explored whether USP15 contributes to PH development by deubiquitinating YAP1 and found that USP15 promoted the stability of YAP1 by inhibiting K48-linked ubiquitination of YAP1."

reach
"USP15 promoted YAP1 stability by inhibiting K48-linked ubiquitination of YAP1."

reach
"Human pulmonary artery smooth muscle cells (hPASMCs) were exposed to hypoxia to mimic PH in vitro, and USP15 knockdown significantly inhibited cell proliferation, migration, and YAP1/TAZ signaling in hypoxic hPASMCs."

reach
"The CHX chase assay further determined that USP15 promoted the protein stability of YAP1 in normoxic hPASMCs (Fig. 8f)."

reach
"Rescue assays further suggested that USP15 promoted hPASMC proliferation and migration in a YAP1/TAZ-dependent manner."

reach
"Taken together, our findings indicate that USP15 might promote PH progression in a YAP1/TAZ-dependent manner (Supplementary Fig. 3)."
