Abstract
Quadruple-negative breast cancer (QNBC) lacks traditional actionable targets, including androgen receptor (AR). QNBC disproportionately afflicts and impacts patients of African genetic ancestry. Kinesin family member C1 (KIFC1/HSET), a centrosome clustering protein that prevents cancer cells from undergoing centrosome-amplification-induced apoptosis, has been reported to be upregulated in TNBCs and African-American (AA) TNBCs. Herein, we analyzed KIFC1 RNA levels and their associations with clinical features and outcomes among AR-low and AR-high TNBC tumors in three distinct publicly available gene expression datasets and in the breast cancer gene expression database (bc-GenExMiner). KIFC1 levels were significantly higher in AR-low and basal-like TNBCs than in AR-high and non-basal-like TNBCs, irrespective of the stage, grade, tumor size, and lymph node status. KIFC1 levels were also upregulated in AR-low tumors relative to AR-high tumors among Black and premenopausal women with TNBC. High KIFC1 levels conferred significantly shorter overall survival, disease-free survival, and distant metastasis-free survival among AR-low and basal-like TNBC patients in Kaplan-Meier analyses. In conclusion, KIFC1 levels may be upregulated in AR-low tumors and, specifically, in those of African descent, wherein it may promote poor outcomes. KIFC1 may be an actionable cancer-cell-specific target for the AR-low TNBC subpopulation and could aid in alleviating racial disparities in TNBC outcomes.

Expression of kinesin family member C1 in pancreatic ductal adenocarcinoma affects tumor progression and stemness. Pathol Res Pract 2023; 241:154277. [PMID: 36565617 DOI: 10.1016/j.prp.2022.154277] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/09/2022] [Accepted: 12/10/2022] [Indexed: 12/23/2022]
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer and the third leading cause of cancer-related deaths. Therefore, there is an urgent need for a novel molecular target for the treatment of PDAC. Kinesin family member C1 (KIFC1) belongs to the kinesin superfamily proteins and has been reported to be involved in the pathogenesis of a wide variety of carcinomas. However, the role of KIFC1 in PDAC remains unknown. This study aimed to analyze the expression and biological function of KIFC1 in PDAC. Immunohistochemically, KIFC1 was found in 37 of 81 PDAC cases (46%). A high expression of KIFC1 was significantly related to tumor size (p = 0.023) and poor overall survival (p = 0.011). Univariate and multivariate analysis indicated that KIFC1 expression was a prognostic factor in PDAC cases. As for cancer stem cell markers, KIFC1 expression tended to co-express significantly with CD44 (p < 0.01). The growth and spheroid colony formation of KIFC1 small interfering RNA (siRNA)-transfected PDAC cells were significantly lower than those of negative control siRNA-transfected cells. Therefore, our findings suggest that KIFC1 is an independent prognostic factor in PDAC and may represent a new promising therapeutic target in PDAC.
