Abstract
Beclin1 is a key regulator of a family of autophagy-related proteins. The aim of our study was to elucidate the clinicopathological and prognostic significance of Beclin1 expression which is a positive regulator of autophagy in cervical cancer. The results showed that a total of 2682 patients were enrolled in 21 case-control studies. The results showed that, as for Beclin1 expression, significant differences were found in cervical cancer vs. normal cervical tissues (p<.00001) and cancer tissues with vs. no lymph node metastasis (p<.00001); tumour diameter no less than vs. less than 4 cm (p=.001), myometrial invasion depth no less than vs. less than 1/2 and FIGO I vs. II (p=.02); relationship between Beclin1 expression and prognosis of cervical cancer (p=.03). Kaplan-Meier's plotter showed that Beclin1 expression was negative. It was associated with overall, post-progressive and distant metastatic survival. According to the Oncomine database, Beclin1 mRNA expression in cervical cancer tissues was higher than that in normal tissues. Cox multivariate showed that lymph node metastasis and TNM stage were important factors affecting the survival time of patients. Beclin1 expression can be used as an indicator of prognosis in patients, and provide methods and ideas for prevention and treatment.

Abstract
As the fourth most diagnosed cancer, cervical cancer (CC) is one of the major causes of cancer-related mortality affecting females globally, particularly when diagnosed at advanced stage. Discoveries of CC biomarkers pave the road to precision medicine for better patient outcomes. High throughput omics technologies, characterized by big data production further accelerate the process. To date, various CC biomarkers have been discovered through the advancement in technologies. Despite, very few have successfully translated into clinical practice due to the paucity of validation through large scale clinical studies. While vast amounts of data are generated by the omics technologies, challenges arise in identifying the clinically relevant data for translational research as analyses of single-level omics approaches rarely provide causal relations. Integrative multi-omics approaches across different levels of cellular function enable better comprehension of the fundamental biology of CC by highlighting the interrelationships of the involved biomolecules and their function, aiding in identification of novel integrated biomarker profile for precision medicine. Establishment of a worldwide Early Detection Research Network (EDRN) system helps accelerating the pace of biomarker translation. To fill the research gap, we review the recent research progress on CC biomarker development from the application of high throughput omics technologies with sections covering genomics, transcriptomics, proteomics, and metabolomics.

Abstract
The inherent structural instability of some physalins has hampered the isolation and identification of these compounds for approximately 50 years, and an effective method to overcome these challenges remains unavailable. In the present study, the unprecedented tautomerization mechanism of unstable physalins was elucidated by performing isotopic labeling experiments and DFT calculations, which led to the successful separation of tautomers and isolation of highly pure products for the first time. As a result, 15 new physalins, physaminins A-O (1-15), as well as 17 known analogues (16-32), were isolated from the whole plants of Physalis minima L. The chemical structures of the new compounds were established by performing a comprehensive analysis of spectroscopic data, and their absolute configurations were confirmed by using computational ECD calculations and/or single-crystal X-ray diffraction analyses. All obtained isolates were evaluated for their antiproliferative effects against four human cancer cell lines (A549, HepG2, MCF-7, and SCG-7901) and two noncancerous cell lines (RAW 264.7 and human normal hepatocytes L02), as well as their anti-inflammatory activities by measuring their abilities to inhibit NO production in LPS-stimulated murine RAW 264.7 cells in vitro. Compounds 1-5, 13, 16, 18, 19, 23, and 30 exerted significant antiproliferative effects on the four human cancer lines, with IC50 values ranging from 0.2(0) to 24.7(2) μM, and these compounds were not toxic to the two noncancerous cell lines at a concentration of 10 μM. Moreover, compounds 7, 10, 11, 12, 14, 17, 22, and 27 significantly inhibited NO production, with IC50 values ranging from 2.9(1) to 9.5(2) μM.
