Cervical cancer is the second most deadly gynecological tumor worldwide. MicroRNAs (miRNAs) play very important roles in tumor oncogenesis and progression. The mechanism of post-transcription regulation of WTX gene is still unknown. A series of differential miRNAs were discovered by microarray analysis comparing three pairs of primary cervical cancer specimens and their relapsed tumors from three patients. Quantitative reverse transcriptase PCR (qRT-PCR), Western Blot (WB) and Immunohistochemistry (IHC) was used to detect the expression of miR-4524b-5p and WTX in cervical cell lines and tissues. The biological function of miR-4524b-5p and WTX was investigated through knockdown and overexpression with inhibitor/siRNA and mimic/plasmid in vitro and in vivo. In this study, we found that miR-4524b-5p is highly expressed in relapsed cervical cancer specimens. Combined in vitro and in vivo experiments, showed that miR-4524b-5p could regulate the migration and invasion ability of cervical cancer. Furthermore, we also found that miR-4524b-5p could regulate the migration and invasion of cervical cancer by targeting WTX and that WTX could regulate the expression of β-catenin. Taken together, our data identified a miR-4524b-5p/WTX/β-catenin regulatory axis for cervical cancer, and miR-4524b-5p may be a potential target for cervical cancer therapy. [ABSTRACT FROM AUTHOR]

Background: Human papillomavirus (HPV) infection is the main etiological factor for the development of cervical cancer. Here we assessed the prevalence and distribution of HPV genotypes in Fujian population.Methods: A total of 8678 women aging from 17 to 84 years olds were recruited from the Fujian Medical University Union Hospital in Fujian Province. Every woman had a face-to-face interview. Cervical samples were collected from each participant and HPV screening was conducted using microarray hybridization.Results: Our study showed that the HPV prevalence in Fujian province was 38.3%. Among the positive individuals, 70.6% were detected for single HPV infection, 29.4% for multiple HPV infections. Further analysis showed that the prevalence of HPV infection significantly increased from 2009 to 2015. The four most common high risk human papillomavirus (HR-HPV) genotypes were HPV16 (8.5%), HPV52 (7.9%), HPV58 (6.2%), HPV 53 (3.5%), collectively accounting for 60.5% of all detected HPV infection. Age subgroup analysis showed two peaks for the frequencies of overall and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 55 years old.Conclusions: HPV infection is becoming serious in Fujian province, which indicates the imperative to implement a HPV vaccination and screening program for this region.

Objective: To investigate the quality of life (QOL) of cervical cancer survivors in China.Methods: Cervical cancer survivors were selected from 4 Tertiary Provincial Hospitals in Changsha, Hunan Province. Enrolled were 140 patients who received cancer treatments in these hospitals from 2007 to 2010. The Functional Assessment of Cancer Therapy-Cervix (FACT-Cx) Questionnaire was used to assess the QOL of the participants. Spiritual well-being was evaluated with the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-Sp). Sexual function was measured with the Female Sexual Functioning Index.Results: The average total FACT-Cx score was 124.45 (70-157). The average FACT-general score was 112.39 (49-150), and the average FACIT-Sp score was 13.9 (2-33.6). The prevalence of sexual dysfunction in our participants was 78%. Factors that were associated with QOL in cervical cancer survivors included gastrointestinal symptoms, health insurance, age, sleep disorders, and the number of complications. Sexual function was affected by radiotherapy, age, type of surgery, sleep disorders, and occupation.Conclusion: The QOL and sexual function of cervical cancer survivors were lower than the general population. Treatment-related complications and sexual dysfunction significantly affected patients' QOL. Having health insurance was associated with better QOL. Sexual function was adversely affected by radiotherapy and radical hysterectomy. [ABSTRACT FROM AUTHOR]
