Purpose: To explore the molecular mechanism of promoting cervical cancer by HSF1 in vivo and in vitro.
Methods: The expression of HSF1 in 110 paraffin-embedded cervical cancer sections of different grades was examined via immunohistochemistry analyses. Expression of HSF1 downstream targets Metadherin (MTDH), VEGF-C and CD31 were studied using immunohistochemistry analyses. HSF1 transcriptional activity in the MTDH promoter region was detected by EMSA, CHIP and luciferase. Cell proliferation and clonality were detected by MTT and clonal formation assay. Cell migration and invasion ability were investigated by scratch analysis and transwell assay. HSF1-mediated tumorigenesis in vivo was examined in xenograft models.
Results: HSF1 expression of cervical cancer cell line was increased compared to normal human cervical tissues. HSF1 enhanced the expression of MTDH, VEGF-C and CD31. HSF1 can combine with MTDH promoter to promote the expression of MTDH. HSF1 enhanced HeLa cell proliferation and clone formation. Furthermore, HSF1 increased HeLa cells migration and invasion in vitro. In the transplanted tumor model, HSF1 inhibited tumor growth in vivo after interference, and reduced the expression of MTDH, VEGF-C and CD31.
Discussion: HSF1 can promote the proliferation, metastasis and invasion of cervical cancer.

Clinical trials are essential to advancing cancer control, yet access and participation remain unequal globally. The World Health Organization (WHO) established the International Clinical Trials Registry Platform (ICTRP) to enable a complete view of interventional clinical research for all those involved in healthcare decision-making and to identify actionable goals to equitable participation at the global level. A review of 89,069 global cancer clinical trials registered in the WHO ICTRP between 1999 and December 2022 revealed a cancer clinical trial landscape dominated by high-income countries and focused on pharmacological interventions, with multinational collaboration limited to only 3% of recruiting trials.

Background: More than 20% of cervical cancers are diagnosed in women older than 65 years. Guidelines recommend screening exit at age 65 for average-risk patients only if certain criteria are met, yet most women aged 64-66 years in the United States are inadequately screened. In this mixed methods study, we explored clinician knowledge of exit criteria.

Colposcopy is an important method for early clinical cervical cancer screening, but the traditional vaginal dilator has problems such as discomfort in use and cumbersome operation. For this reason, this study aims to design an intelligent vaginal dilatation system to automate colposcopy and enhance patient comfort.

Background: Cancer screening nonadherence persists among adults who are deaf, deafblind, and hard of hearing (DDBHH). These barriers span individual, clinician, and health care system levels, contributing to difficulties understanding cancer information, accessing screening services, and following treatment directives. Critical communication barriers include ineffective patient-physician communication, limited access to American Sign Language (ASL) cancer information, misconceptions about medical procedures, insurance navigation difficulties, and intersectional barriers for multiply marginalized individuals.
