[PMID: 38749173 DOI: 10.1016/j.biopha.2024.116719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 05/02/2024] [Accepted: 05/06/2024] [Indexed: 06/03/2024] Open
Abstract
INTRODUCTION Head and neck squamous cell carcinoma (HNSCC) is a common cancer with a five-year survival rate around 60%, indicating a need for new treatments. BH3 mimetics are small molecules that inhibit anti-apoptotic Bcl-2 family proteins, resulting in apoptosis induction. METHODS We performed a high-throughput screen using a Myogel matrix to identify the synergy between irradiation and the novel BH3 mimetics A-1155463, A-1331852, and navitoclax in 12 HNSCC cell lines, normal (NOF) and cancer-associated fibroblasts (CAF), and dysplastic keratinocytes (ODA). Next, we examined synergy in an apoptosis assay, followed by a clonogenic assay and a Myogel spheroid on selected HNSCC cell lines. Finally, we applied zebrafish larvae xenograft to validate the effects of navitoclax and A-1331852. RESULTS All three BH3 mimetics exhibited a strong synergy with irradiation in eight HNSCC cell lines and ODAs, but not in NOFs and CAFs. A-1155463 and A-1331852 induced apoptosis and reduced proliferation, and together with irradiation, significantly increased apoptosis and arrested proliferation. A-1331852 and navitoclax significantly decreased the clonogenicity compared with the control, and combination treatment led to a decreased clonogenicity compared with monotherapy or irradiation. However, unlike navitoclax or A-1155463, only A-1331852 significantly reduced cancer cell invasion. Furthermore, in spheroid and zebrafish, irradiation appeared ineffective and failed to significantly increase the drug effect. In the zebrafish, A-1331852 and navitoclax significantly reduced the tumor area and metastasis. CONCLUSIONS Our findings encourage the further preclinical investigation of BH3 mimetics, particularly A-1331852, as a single agent or combined with irradiation as a treatment for HNSCC.

Abstract
Excessive fat intake leads to an increase in cholesterol. Overexposure to estrogen derived from cholesterol is known to contribute to the malignancy of endometrial adenocarcinomas. However, it is not well understood the relationship between the exposure to estrogen and the malignancy of endometrial adenocarcinomas. We investigated how estrogen affected the malignancy of endometrial cancer cells, specifically HEC1 cells (a moderately differentiated adenocarcinoma) and HEC50B cells (a poorly differentiated adenocarcinoma). Cell viability was decreased by exogenous 17-β-estradiol (E2) in a concentration-dependent manner. E2 disturbed the mitochondrial membrane potentials by changing the localization of the B-cell lymphoma 2 (Bcl-2) family protein; however, there were significant differences in the localization of Bcl-2 family proteins between HEC1 and HEC50B cells. In HEC1 cells, E2 increased the expression of B-cell lymphoma-extra large (Bcl-XL) and the Bcl-2-associated X protein (Bax) and decreased Bcl-2 and Bcl-2-associated death promoter (Bad) expression on the outer mitochondrial membrane. Conversely, E2 increased the expression of Bad and Bax, and it decreased Bcl-2 and Bcl-XL expressions on the outer mitochondrial membrane in HEC50B cells. The disturbance of the mitochondrial membrane potential led to the release of cytochrome c from the mitochondria to the cytosolic space followed by activating caspase-9. After that, caspase-3 was activated and induced apoptosis. These results suggested that the localization of the Bcl-2 family protein observed under E2-induced apoptosis is related to the malignancy of endometrial cancer cells. We hope that the dynamics of Bcl-2 family proteins such as Bcl-XL and Bad will be used to diagnose malignant endometrial adenocarcinomas.

Abstract
BACKGROUND Human Papillomavirus (HPV) infection is well established in oropharyngeal squamous cell carcinoma (OPSCC) and cervical cancer (CC). However, the association between both HPV related cancers remains unclear. The purpose of this study was to investigate the association between HPV related cancers of the oropharynx and cervix. METHODS A provincial cancer registry was used to retrospectively identify all patients diagnosed with OPSCC from 1997-2015. The standardized incidence ratio (SIR) of CC history in women with p16+/-OPSCC was measured. RESULTS From 372 women with OPSCC included, the SIR of CC was significantly higher across all ages compared to the general population in Alberta, Canada (p < 0.0001). CONCLUSIONS Women with HPV/p16+ OPSCC have a significantly higher risk of CC compared to the general population.
