Zeng FanhuaYang ZhenhuaWang Zufeng - Recent studies have demonstrated that PLEKHA4 promotes tumor growth in some cancers, such as small-cell lung cancer, melanoma, and hepatic carcinomas; however, the underlying mechanism in glioblastoma remains ambiguous. Bioinformatic was used to analysis PLEKHA4 expression. In vitro and in vivo experiments were conducted to detect the effect of PLEKHA4 on glioblastoma cell glycolytic reprogramming and progression. GSEA was used to analyze the signal pathways related to PLEKHA4. Pharmacological methods further validated the role of activation pathways. We evaluated the effects of PLEKHA4 knockdown combined with temozolomide (TMZ) on glioblastoma cell proliferation and apoptosis in vitro and in vivo. We observed an overexpression of PLEKHA4 in GBM cell lines, resulting in enhanced cell proliferation, inhibited apoptosis, and promoted glycolysis. Mechanistically, our study demonstrated that PLEKHA4 mediates cell proliferation, apoptosis, and glycolysis via the STAT3/SOCS1 signaling pathway. Additionally, HOXD9 was predicted using Jasper, which is a transcription factor that binds to the PLEKHA4 promoter region. Knocking down PLEKHA4 combined with TMZ inhibited cell proliferation and promoted cell apoptosis in vitro and in vivo. Our results indicated that HOXD9-medicated PLEKHA4 regulates glioblastoma cell proliferation and glycolysis via activation of the STAT3/SOCS1 pathway. - Source: PubMed

Zhang DainanWang XiaoyinXiao MengMa ShunchangLi ShaominJia Wang - Malignant melanoma (MM) is a highly aggressive subtype of skin cancer characterized by a poor prognosis, particularly in the advanced stages. Despite advancements in targeted therapy and immunotherapy, the survival rates for MM remain low, underscoring the need for new therapeutic targets. Pleckstrin homology domain‑containing family A member 4 (PLEKHA4), which has regulatory functions in pivotal cellular processes, has emerged as a potential target in melanoma. The present study aimed to investigate the role of PLEKHA4 in melanoma progression, focusing on its influence on the MAPK and Wnt/β‑catenin signaling pathways. Bioinformatics analysis revealed that PLEKHA4 was upregulated in melanoma tissues, whereas PLEKHA4 knockdown in melanoma cell lines (A375 and A2058) significantly inhibited cell proliferation and migration, enhanced apoptosis and inhibited tumor growth . Mechanistic studies demonstrated that PLEKHA4 may exert its effects by modulating the MAPK signaling pathway through interactions with key proteins, including ERK, JNK and MEK. Additionally, PLEKHA4 was shown to impact apoptosis by regulating caspase‑3, COX2 and p65. Additionally, β‑catenin nuclear translocation was affected via the Wnt pathway. Moreover, PLEKHA4 knockdown reduced cMyc ubiquitination, consequently promoting its degradation. The present findings suggested that PLEKHA4 could promote melanoma cell proliferation by regulating both the MAPK and Wnt/β‑catenin pathways, thereby proposing PLEKHA4 as a promising therapeutic target for MM. Further studies are warranted to elucidate the mechanisms underlying PLEKHA4‑mediated modulation of cMyc ubiquitination. - Source: PubMed

Yue YuyangAn GuangqiCao ShuxiaLi XiangdanDu LipingXu DongyuanLiu Lan - In the present study, pleckstrin homology domain‑containing family A member 4 (PLEKHA4) was identified as being upregulated in renal cell carcinoma, particularly within the kidney renal clear cell carcinoma (KIRC) subtype. The present study conducted bioinformatics analysis, Cell Counting Kit‑8 and cell migration assays, flow cytometry, western blotting and experiments with the aim of uncovering the role of PLEKHA4 in β‑catenin signaling in KIRC cells. Notably, PLEKHA4 upregulation was revealed to be associated with enhanced cell proliferation, indicating its potential role as an oncogene in KIRC. Mechanistically, knockdown of PLEKHA4 in KIRC cells led to decreased β‑catenin signaling and cyclin D1 expression and the induction of cell cycle arrest at the G1/S phase, suggesting that PLEKHA4 facilitated tumorigenesis through modulation of the Wnt/β‑catenin pathway. PLEKHA4 knockdown also inhibited cell viability, migration and colony formation, further emphasizing its role in cancer progression. Notably, overexpression of PLEKHA4 activated Wnt/β‑catenin signaling, reinforcing its role in promoting β‑catenin nuclear translocation and signaling activity. The present findings suggested that PLEKHA4 could serve as a potential therapeutic target for KIRC; inhibiting PLEKHA4 or modulating Wnt/β‑catenin signaling could provide new avenues for treatment strategies in KIRC. - Source: PubMed
