| 1 | 富含半胱氨酸分泌蛋白生物学功能的研究进展显示文摘富含半胱氨酸分泌蛋白(cysteine-rich secretory proteins,CRISPs)包含众多不同起源的蛋白质,其大部分成员功能未知。近年来研究发现,哺乳动物中的CRISP家族各成员主要存在于生殖道中,在精子的成熟、精卵融合以及免疫系统中发挥着非常重要的作用,并且其表达水平的改变与人类多种重大疾病密切相关,有望成为某些疾病理想的生物标记物和药物靶点;而非哺乳动物中的CRISP家族成员则主要存在于腺体的分泌液中,能够阻断Na+、K+、Ca2+及环核苷酸门控通道,并与炎症反应密切相关。近来,作者所在实验室从低等无颌类脊椎动物七鳃鳗的口腔腺中分离纯化出富含半胱氨酸分泌蛋白,其与CRISP家族成员具有较高的同源性。该文针对CRISP家族成员生物学功能的最新进展做了分析归纳,并指出了相关研究的发展趋势。 | 刘宇 肖蓉 杨东辉 刘欣 李庆伟 | 2013 | 中国细胞生物学学报2013，35，3： | 4 |
| 2 | Loss of PSP94 expression is associated with early PSA recurrence and deteriorates outcome of PTEN deleted prostate cancers显示文摘Objective: Prostate secretory protein of 94 amino acids(PSP94) is a target gene of the EZH2 transcriptional repressor and is often downregulated in prostate cancer;however, its prognostic value is disputed.Methods: Immunohistochemical analysis of a tissue microarray of 12, 432 prostate cancer specimens was performed to evaluate PSP94 expression. Correlation of PSP94 expression with tumor phenotype, patient prognosis, TMPRSS2:ERG fusion status, EZH2 expression and PTEN deletion was studied.Results: PSP94 expression was increased in benign prostatic hyperplasia;however, it was downregulated in 48% and negative in42% of the 9, 881 interpretable prostate cancer specimens. The loss of PSP94 expression was inversely correlated to EZH2 expression(P < 0.0001) and largely unrelated to the ERG status, but strongly correlated with high Gleason grade, advanced tumor stage, and nodal metastasis(P <0.0001 each). The fraction of PSP94-negative cancer specimens increased from 40% in pT2 to 52%in pT3 b-pT4(P < 0.0001) and from 40% in Gleason 3+3 = 6 to 46% in Gleason 4+3 = 7 and 60% in Gleason ≥4+4 = 8(P <0.0001). Loss of PSP94 was linked to early prostate-specific antigen recurrence, but with little absolute effect(P < 0.0001).However, it provided additional prognostic impact in cancer specimens with PTEN deletion. Loss of PSP94 deteriorated prognosis of cancer patients with PTEN deletion by more than 10%(P < 0.0001). The combination of PTEN deletion and PSP94 loss provided independent prognostic information that was observed in several subgroups defined by classical and quantitative Gleason grade.Conclusions: The results of our study suggest that combined PSP94/PTEN analysis can be potentially used in the clinical prognosis of prostate cancer. | Andreas M.
