Abstract
Chromodomain helicase/ATPase DNA-binding protein 1-like gene (CHD1L) is a new oncogene which has been confirmed to be crucial to the progression of many solid tumors. In the present study, the expression of CHD1L was found to be upregulated in intrahepatic cholangiocarcinoma (ICC), which was significantly associated with histological differentiation (P=0.011), vascular invasion (P=0.002), lymph node metastasis (P=0.008) and TNM stage (P=0.001). Kaplan-Meier survival analysis revealed that ICC patients with positive CHD1L expression had shorter overall and disease-free survival than those with negative CHD1L expression. Functional study found that CHD1L exhibited strong oncogenic roles, including increased cell growth by CCK-8 assay, colony formation by plate colony formation assay, G1/S transition by flow cytometry and tumor formation in nude mice. In addition, RNAi-mediated silencing of CHD1L inhibited ICC invasion and metastasis by wound healing, Transwell migration and Matrigel invasion assays in vitro and in vivo. Collectively, our results show that CHD1L is upregulated and promotes the proliferation and metastasis of ICC cells. CHD1L acts as an oncogene and may be a prognostic factor or therapeutic target for patients with ICC.

Koya Y, Liu W, Yamakita Y, Senga T, Shibata K, Yamashita M, Nawa A, Kikkawa F, Kajiyama H. Hematopoietic lineage cell-specific protein 1 (HS1), a hidden player in migration, invasion, and tumor formation, is over-expressed in ovarian carcinoma cells. Oncotarget 2018; 9:32609-32623. [PMID: 30220969 PMCID: PMC6135686 DOI: 10.18632/oncotarget.25975] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Accepted: 07/31/2018] [Indexed: 12/12/2022] Open
Abstract
Hematopoietic lineage cell-specific protein 1 (HS1), which is the hematopoietic homolog of cortactin, is an actin-binding protein and Lyn substrate. It is upregulated in several cancers and its expression level is associated with increased cell migration, metastasis, and poor prognosis. Here we investigated the expression and roles of HS1 in ovarian carcinoma cells. We analyzed the expression of HS1 in 171 ovarian cancer specimens and determined the association between HS1 expression and clinicopathological characteristics, including patient outcomes. In patients with stage II-IV disease, positive HS1 expression was associated with significantly worse overall survival than negative expression (P < 0.05). HS1 was localized in invadopodia in some ovarian cancer cells and was required for invadopodia formation. Migration and invasion of ovarian cancer cells were suppressed by down-regulation of HS1, but increased in cells that over-expressed exogenous HS1. Furthermore, ovarian cancer cells that expressed HS1 shRNA exhibited reduced tumor formation in a mouse xenograft model. Finally, we found that tyrosine phosphorylation of HS1 was essential for cell migration and invasion. These findings show that HS1 is a useful biomarker for the prognosis of patients with ovarian carcinoma and is a critical regulator of cytoskeleton remodeling involved in cell migration and invasion.
