| 1 | Evaluation of triage strategies for high-risk human papillomavirus-positive women in cervical cancer screening:A multicenter randomized controlled trial in different resource settings in China显示文摘Objective:We aimed to evaluate the effectiveness of different triage strategies for high-risk human papillomavirus(hrHPV)-positive women in primary healthcare settings in China.Methods:This study was undertaken in 11 rural and 9 urban sites.Women aged 35-64 years old were enrolled.HrHPV-positive women were randomly allocated to liquid-based cytology(LBC),visual inspection with acetic acid and Lugol’s iodine(VIA/VILI)(rural only)triage,or directly referred to colposcopy(direct COLP).At 24 months,hrHPV testing,LBC and VIA/VILI were conducted for combined screening.Results:In rural sites,1,949 hrHPV-positive women were analyzed.A total of 852,218 and 480 women were randomly assigned to direct COLP,LBC and VIA/VILI.At baseline,colposcopy referral rates of LBC or VIA/VILI triage could be reduced by 70%-80%.LBC(n=3 and n=7)or VIA/VILI(n=8 and n=26)could significantly decrease the number of colposcopies needed to detect one cervical intraepithelial neoplasia(CIN)2 or worse and CIN3+compared with direct COLP(n=14 and n=23).For the 24-month cumulative detection rate of CIN2+,VIA/VILI triage was 0.50-fold compared with LBC triage and 0.46-fold with the direct COLP.When stratified by age,baseline LBC triage+performed best(P<0.001),peaking among women aged 35-44 years(Ptrend=0.002).In urban sites,1,728 women were hrHPV genotyping test positive.A total of 408,571 and 568women were randomly assigned to direct COLP for HPV16/18+,direct COLP for other hrHPV subtypes+,and LBC triage for other hrHPV subtypes+.LBC(n=12 and n=31)significantly decreased the number of colposcopies needed to detect one CIN2+and CIN3+compared with direct COLP(n=14 and n=44).HPV16/18+increased the 24-month cumulative detection rate of CIN2+(17.89%,P<0.001).Conclusions:LBC triage for hrHPV-positive women in rural settings and direct COLP for HPV16/18+women and LBC triage for other hrHPV subtype+women in urban settings might be feasible strategies. | Le Dang Linghua Kong Yuqian Zhao Yi Dai Li Ma Lihui Wei Shulan Zhang Jihong Liu Mingrong Xi Long Chen Xianzhi Duan Qing Xiao Guzhalinuer Abulizi Guonan Zhang Ying Hong Qi Zhou Xing Xie Li Li Mayinuer Niyazi Zhifen Zhang Jiyu Tuo Yiling Ding Youlin Qiao Jinghe Lang | 2022 | Chinese Journal of Cancer Research2022，34，5： | 2 |
| 2 | Methyltransferase 3A-mediated promoter methylation represses retinoic acid receptor responder 3 expression in basal-like breast cancer显示文摘Retinoic acid receptor responder 3(RARRES3)has been characterized as a tumor suppressor in multiple types of cancer.This study aimed to examine the expression profile of RARRES3 across the PAM50 subtypes of breast cancer.The DNA methylation status of RARRES3 was checked in the basal-like subtype,and the underlying mechanisms of its dysregulation were explored.RNA-sequencing(seq)and methylation data from The Cancer Genome Atlas were used for in-silico analysis.Basal-like representative SUM149 and MDA-MB-468 cell lines were used for in vitro and in vivo studies.Compared to tumor-adjacent normal tissues,only the basal-like tumor tissues had significantly downregulated RARRES3 expression.The methylation level of four CpG sites in the promoter region showed a strong negative correlation with RARRES3 expression.The gene coding for DNA methyltransferase 3A(DNMT3A)had consistent positive correlations with the methylation of the CpG sites.Chromatin Immunoprecipitation-quantitative polymerase chain-reaction and bisulfite sequencing PCR showed that DNMT3A could bind to the promoter region of RARRES3 and promote methylation of the CpG sites within the region.DNMT3A knockdown significantly restored RARRES3 expression at the mRNA and protein level in the two cell lines.CCK-8,colony formation,and flow cytometric analysis showed that RARRES3 overexpression attenuated the growth-promoting effects of DNMT3A overexpression and also weakened the DNMT3A overexpression-induced activation of ERK1/2 and PI3K/AKT signaling.In summary,this study revealed that DNMT3A enhances promoter methylation of the RARRES3 gene and suppresses its transcription in basal-like breast cancer.The DNMT3A-RARRES3 signaling pathway might be a potential target for the treatment of this tumor subtype. | YOULIN TUO XUBAO LIU | 2023 | BIOCELL2023，47，2： | 0 |
