摘要:
目的:研究黑碳颗粒(BC)对肺上皮细胞衰老的影响,以及西施舌提取物对衰老肺上皮细胞的保护作用与可能机制.方法:分离、纯化新生SD大鼠的肺上皮细胞,将细胞分为3组,分别为正常组、BC刺激组、BC刺激+西施舌提取物保护组.RT-qPCR法检测各组细胞P16与Rb mRNA的表达水平,Western blot法(蛋白质印迹法)检测各组细胞P16和Rb的蛋白表达水平.结果:BC刺激组肺上皮细胞P16与Rb mRNA和蛋白表达均较正常组增高(P<0.05);西施舌提取物保护组肺上皮细胞P16与Rb mRNA和蛋白表达均较BC刺激组下降(P<0.05).结论:BC刺激能加速肺上皮细胞的衰老,西施舌提取物能延缓这种衰老的程度,两者的作用机制可能与P16/Rb细胞信号转导通路有关.

摘要:
目的 探讨乳腺良恶性病变中人乳头状瘤病毒(HPV)16/18型感染和Rb蛋白的表达状态及其相关性.方法 收集2016年1月—2017年12月广西壮族自治区柳州市人民医院乳腺外科乳腺手术切除标本为研究对象,其中浸润性导管癌(IDC)68例为IDC组、乳腺不典型导管上皮增生(ADH)30例为ADH组、乳腺纤维腺瘤旁正常乳腺组织30例为正常乳腺组.原位杂交法检测HPV16/18 DNA,免疫组织化学检测Rb蛋白的表达情况.结果 IDC组中HPV16/18 DNA阳性率高于正常乳腺组和ADH组;Rb蛋白阳性表达率低于正常乳腺组和ADH组(均P<0.05).三组HPV16/18 DNA感染与Rb蛋白表达均呈负相关性(r=-0.802、-0.774、-0.802,均P<0.05).IDC患者HPV16/18DNA、Rb蛋白的表达与组织学分级、淋巴结转移和pTNM分期密切相关(P<0.01).结论 HPV16/18型感染和Rb蛋白的表达缺失可能涉及人乳腺癌的发生、发展过程.

摘要:
Objective To investigate the correlation between human papilloma virus(HPV) 16/18 infection and the expression of Rb and p16 protein in bladder cancer tissue,and to analyze the relationship between HPV infection and the incidence of bladder cancer.Methods The expression of HPV16/18 E6 and E7 gene encoded protein,RB and p16 were detected by immunohistochemical method in 40 cases of bladder cancer and 40 cases of normal bladder tissues,and the correlation between them and pathological grading,stage of international union of cancer(UICC),whether recurrence or not after receiving surgery was analyzed.Results In bladder cancer tissues,HPV16/18 E6 and E7 gene encoded protein,RB and p16 positive rates were 65%,47.5%,42.5%,compared with the positive rate of normal bladder tissue samples(22.5%,92.5%,87.5%),the differences were statistically significant(P0.05).The expression of HPV16/18 E6 and E7 gene encoded protein and Rb,p16 protein were not significantly correlated(P>0.05),The expression of Rb and p16 protein were negatively correlated(P0.05);HPV16/18 E6/E7蛋白与Rb及p16蛋白的表达均无显著相关(P>0.05),Rb与p16蛋白的表达呈显著负相关(P<0.05).结论 HPV 16/18感染与膀胱癌的发生及发展有关,但其作用机制可能与Rb及p16蛋白的表达异常无关.

摘要:
Objective To investigate the expression of MCM7,Rb,c-MYC protein in hepatocellular carcinoma tissues and its effect on gene passageway .Methods Tumor tissues of 60 cases of hepatocellular carcinoma were performed immunohisto-chemistry stain,the expression of MCM7,Rb and c-MYC genes in hepatocellular carcinoma were analyzed .Results MCM7 pro-tein expressed only in HCC tissue(73.3%),which was significantly higher than normal liver tissues and liver cirrhosis tissues (P0.05).Positive rate of c-MYC protein in HCC tissue(70.0%) was significantly higher than that in liver cirrhosis tissues(35.0%)(P0.05).The expression of Rb was related to differentiation degree only(P0.05);肝细胞癌组织(70.0%)中c-MYC蛋白阳性率显著高于肝硬化组织(35.0%)(P0.05);Rb蛋白的表达仅与肿瘤组织分化程度有关(P<0.05);c-MYC蛋白表达与肿瘤组织分化程度和是否转移有关(P<0.05).MCM7蛋白和Rb阳性率呈显著负相关(γ=-0.712,P=0.038;γ=-0.664,P=0.018).结论 肝细胞癌的发生是多基因多通路相互作用的结果,多种调控蛋白的异常共同导致肿瘤的发生.

摘要:
目的::探讨MDM2、Rb蛋白表达在喉鳞状细胞癌中的诊治价值。方法:采用免疫组化法对鳞状细胞癌组、癌前病变组、声带息肉组、癌周正常组患者MDM2、Rb蛋白表达进行检测,分析其与肿瘤变化的关系。结果:喉鳞状细胞癌组、癌前病变组、声带息肉组、癌周正常组MDM2检测结果逐渐下降,鳞状细胞癌组最高,且组间比较差异有统计学意义,P<0.05;四组Rb检测结果逐渐升高,鳞状细胞最小,P<0.05;MDM2与Rb蛋白表达在喉鳞状癌患者中呈负相关性(Rs=-0.563,P<0.05)。结论:MDM2、Rb蛋白表达可以作为预测早期喉鳞状细胞癌的依据。%Objective:To investigate the expression of MDM2 and Rb Protein for laryngeal squamous cell carcinoma. Methods:Immunohistochemical staining was used for squamous cell carcinoma group, precancerous lesions group, vocal cord polyps group and peritumoral patients to determine the MDM2 and Rb protein expression, and the changes and the relationship with the tumor were analyzed.Results:The MDM2 of the squamous cell carcinoma group, precancerous lesions group, vocal cord polyps group and peritumoral group was gradually decline, which was the highest in the squamous cell carcinoma group(P<0.05). While the Rb was gradually increased and the squamous cell carcinoma group was the least(P<0.05). There was negative correlationbetween the MDM2 and Rb protein expression in laryngeal squamous carcinoma (Rs=-0.563, P<0.05).Conclusion:The MDM2 and Rb protein expression might be a predictor basis of early laryngeal squamous cell carcinoma.

摘要:
目的探讨人乳头瘤病毒( Human papillomavirus, HPV)感染, Rb蛋白和Mcl-1蛋白表达的变化同非小细胞肺癌(Non-small-cell lung cancer, NSCLC)的相关性。方法分别应用PCR、免疫组化方法(IHC)检测NSCLC组(79例)和肺良性病变组(11例)中HPV DNA表达和Rb蛋白、 Mcl-1蛋白的表达。结果在NSCLC组织中, HPV DNA的PCR检测阳性检出率为46.8%,肺良性病变组阳性检出率为9.1%( P<0.05), HPV阳性表达与组织学类型、分化程度及吸烟相关。 NSCLC中HPV阳性组Rb蛋白表达阳性率(37.8%)显著低于阴性组(61.9%)(P<0.05)。 NSCLC中HPV阳性组和阴性组Mcl-1蛋白表达阳性率分别为59.5%和35.7%(P<0.05)。肺良性病变组中Rb蛋白表达阳性率为72.7%而Mcl-1蛋白未表达。结论 NSCLC的发生发展可能与HPV感染后通过抑制Rb蛋白通路同时促进Mcl-1蛋白通路表达有关。%Objective To study the relationship between HPV ( Human papillomavirus, HPV) infection, the expression of Rb&Mcl-1 protein and the non-small cell lung cancer ( Non-small-cell Lung Cancer, NSCLC) . Methods PCR and Immunohistochemis-try (IHC) were used to detect HPV DNA expression and protein expression of Rb and Mcl-1 in NSCLC group (79 cases) and benign lung lesion group (11 cases). Results The positive rate of HPV in NSCLC group is 46.8% , and the positive rate of HPV in lung benign lesion group is 9.1% (P<0.05). HPV positive expression is related to histological type, degree of differentiation and smoking. Rb protein positive expression in HPV-positive group ( 37.8%) is significantly lower than the negative group ( 61.9%) in NSCLC ( P<0.05 ) . Mcl-1 protein positive expression in HPV-positive group ( 59.5%) is significantly lower than the negative group (35.7%) in NSCLC (P<0.05). In benign lesion group, the rate of Rb protein expression is 72.7%, but Mcl-1 protein is not ex-pressed. Conclusion Development of NSCLC is related to HPV infection by inhibiting the Rb protein pathway and promoting Mcl-1 protein pathway.
