| 1 | Histone deacetylase inhibitors inhibit cervical cancer growth through Parkin acetylationmediated mitophagy显示文摘Parkin,an E3 ubiquitin ligase,plays a role in maintaining mitochondrial homeostasis through targeting damaged mitochondria for mitophagy.Accumulating evidence suggests that the acetylation modification of the key mitophagy machinery influences mitophagy level,but the underlying mechanism is poorly understood.Here,our study demonstrated that inhibition of histone deacetylase(HDAC)by treatment of HDACis activates mitophagy through mediating Parkin acetylation,leading to inhibition of cervical cancer cell proliferation.Bioinformatics analysis shows that Parkin expression is inversely correlated with HDAC2 expression in human cervical cancer,indicating the low acetylation level of Parkin.Using mass spectrometry,Parkin is identified to interact with two upstream molecules,acetylase acetyl-Co A acetyltransferase 1(ACAT1)and deacetylase HDAC2.Under treatment of suberoylanilide hydroxamic acid(SAHA),Parkin is acetylated at lysine residues 129,220 and 349,located in different domains of Parkin protein.In in vitro experiments,combined mutation of Parkin largely attenuate the interaction of Parkin with PTEN induced putative kinase 1(PINK1)and the function of Parkin in mitophagy induction and tumor suppression.In tumor xenografts,the expression of mutant Parkin impairs the tumor suppressive effect of Parkin and decreases the anticancer activity of SAHA.Our results reveal an acetylation-dependent regulatory mechanism governing Parkin in mitophagy and cervical carcinogenesis,which offers a new mitophagy modulation strategy for cancer therapy. | Xin Sun Yuhan Shu Guiqin Ye Caixia Wu Mengting Xu Ruilan Gao Dongsheng Huang Jianbin Zhang | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 3 |
| 2 | Effectiveness of tonifying-kidney and regulating-liver therapy on diminished ovarian reserve: a systematic review and Meta-analysis of randomized controlled trials显示文摘OBJECTIVE: To evaluate the effectiveness of the Traditional Chinese Medicine tonifying-kidney and regulating-liver therapy on diminished ovarian reserve(DOR).METHODS: The literature was comprehensively searched up to August 2019 using four Chinese and three English electronic databases to extract randomized clinical trials(RCTs) comparing Traditional Chinese Medicine tonifying-kidney and regulating-liver prescriptions(combined with hormone therapy or not) with Western Medicine. Data quality evaluation was conducted using the Cochrane risk of bias tool. Meta-analysis was conducted using Revman 5.3 software with effect estimates presented as mean difference(MD), risk ratio(RR), and95% confidence interval(CI).RESULTS: A total of nine RCTs with 512 participants were extracted and eligible for Meta-analysis.There were no significant differences between Chinese medicine and Western Medicine on basal serum follicle-stimulating hormone(FSH) level(MD0.11, 95% CI-0.52 to 0.74, 392 participants, seven trials), anti-Müllerian hormone level(MD 0.48, 95%CI-0.62 to 1.58, 95 participants, two trials), and the FSH and luteinizing hormone ratio(MD 0.01,95% CI-0.95 to 0.96, 115 participants, two trials).Chinese medicine was more effective at improving Traditional Chinese Medicine symptom scores(TCMSS)(MD-2.39, 95% CI-3.83 to-0.94, 160 participants, three trials), effective rate of TCMSS(RR1.18, 95% CI 1.02 to 1.36, 160 participants, three trials), antral follicle count(AFC)(MD 0.55, 95% CI 0.05 to 1.04, 155 participants, three trials), and FSH levels at 3 months post-treatment(MD-4.77, 95% CI-6.09 to-3.45, 137 participants, two trials).CONCLUSION: Compared with Western Medicine,tonifying-kidney and regulating-liver therapy is more effective at relieving symptoms and improving AFC and FSH at 3 months post-treatment. | Liu Liuqing Liu Yanfeng Yang Ming Xu Guiqin Li Ruiqi Xu Xiuli Pan Xue Liang Jialing | 2020 | Journal of Traditional Chinese Medicine2020，40，3： | 3 |

| 6 | Low-Cost and Scalable Platform with Multiplexed Microwell Array Biochip for Rapid Diagnosis of COVID-19显示文摘Sensitive detection of SARS-CoV-2 is of great importance for inhibiting the current pandemic of COVID-19.Here,we report a simple yet efficient platform integrating a portable and low-cost custom-made detector and a novel microwell array biochip for rapid and accurate detection of SARS-CoV-2.The instrument exhibits expedited amplification speed that enables colorimetric read-out within 25 minutes.A polymeric chip with a laser-engraved microwell array was developed to process the reaction between the primers and the respiratory swab RNA extracts,based on reverse transcriptase loop-mediated isothermal amplification(RT-LAMP).To achieve clinically acceptable performance,we synthesized a group of six primers to identify the conserved regions of the ORF1ab gene of SARS-CoV-2.Clinical trials were conducted with 87 PCR-positive and 43 PCRnegative patient samples.The platform demonstrated both high sensitivity(95.40%)and high specificity(95.35%),showing potentials for rapid and user-friendly diagnosis of COVID-19 among many other infectious pathogens. | Yang Wang Kaiju Li Gaolian Xu Chuan Chen Guiqin Song Zaizai Dong Long Lin Yu Wang Zhiyong Xu Mingxia Yu Xinge Yu Binwu Ying Yubo Fan Lingqian Chang Jia Geng | 2021 | Research2021，，1： | 0 |
