SYT7 as a Potential Prognostic Marker Promotes the Metastasis of Epithelial Ovarian Cancer Cells by Activating the STAT3 Pathway.

The study aimed to investigate the impact of synaptotagmin 7 (SYT7) on the metastasis of epithelial ovarian cancer (EOC) and its potential mechanisms. This was achieved through the analysis of SYT7 expression levels and clinical relevance in EOC using bioinformatics analysis from TCGA. Additionally, the study examined the influence of SYT7 on the migration and invasion of EOC cells, as well as explored its molecular mechanisms using in vitro EOC cell lines and in vivo mouse xenograft models.

Progestin plus metformin improves outcomes in patients with endometrial hyperplasia and early endometrial cancer more than progestin alone: a meta-analysis.

Objective: Progestin based therapy is the preferred option for fertility-sparing treatment of reproductive-age women with preserved fertility in endometrial hyperplasia (EH) or early endometrial cancer (EEC). Our objective was to investigate whether metformin could enhance the efficacy of progestin-based therapies by meta-analysis.

Methods: We conducted a meta-analysis of randomized or non-randomized controlled trials by searching of PubMed, Embase, Web of science, and Cochrane database from inception to November 8, 2022.

lncRNA GAS5 suppression of the malignant phenotype of ovarian cancer via the miR-23a-WT1 axis.

Background: Growth arrest-specific 5 (GAS5) is a long noncoding RNA (lncRNA) that regulates cell viability. GAS5 lncRNA has been shown to decrease colorectal and breast cancer carcinogenesis. Although the function and mechanisms related to lncRNA GAS5 in the development of ovarian cancer (OC) remains unclear.

LY294002 Is a Promising Inhibitor to Overcome Sorafenib Resistance in FLT3-ITD Mutant AML Cells by Interfering With PI3K/Akt Signaling Pathway.

Internal tandem duplications (ITD) mutation within FMS-like tyrosine kinase 3 (FLT3), the most frequent mutation happens in almost 20% acute myeloid leukemia (AML) patients, always predicts a poor prognosis. As a small molecule tyrosine kinase inhibitor, sorafenib is clinically used for the treatment of advanced renal cell carcinoma (RCC), hepatocellular carcinoma (HCC), and differentiated thyroid cancer (DTC), with its preclinical and clinical activity demonstrated in the treatment of Fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutant AML. Even though it shows a rosy future in the AML treatment, the short response duration remains a vital problem that leads to treatment failure.

Inhibition of FOSL2 aggravates the apoptosis of ovarian cancer cells by promoting the formation of inflammasomes.

Background: Ovarian cancer is a common gynecological malignancy among female patients and poses a serious threat to women's health. Although it has been established that Fos-like antigen 2 (FOSL2) is linked to ovarian cancer (OC), its exact role in the development of OC remains unknown.

Objective: This article aims to investigate the role of FOSL2 in ovarian cancer development.

PARP inhibitors in breast and ovarian cancer with BRCA mutations: a meta-analysis of survival.

Objective: To evaluate the efficacy of poly ADP ribose polymerase (PARP) inhibitors (PARPis) in breast and ovarian cancer with (BReast CAncer susceptibility gene) mutation (BRCAm).

Methods: We conducted a meta-analysis of randomized controlled, phase II or III trials by searching of electronic databases from inception to September 1, 2020. The efficacy of PARPis measured by hazard ratios (HRs) and 95% confidence intervals (95% CIs) for progression free survival (PFS) and overall survival (OS) of patients.

Objective: To explore the potential clinical value of platelet parameters in early pregnancy in predicting gestational diabetes mellitus (GDM).

Methods: A total of 1188 singleton pregnant women were included in the regular antenatal examination and delivered in the First Affiliated Hospital of Sun Yat-Sen University from January 2016 to December 2018, who had no pre-pregnancy diabetes, no factors leading to elevated blood glucose level, no medical complications and no other obstetrical complications. Blood routine examination was performed at the 11-13 gestational weeks.

Fucosterol exhibits selective antitumor anticancer activity against HeLa human cervical cell line by inducing mitochondrial mediated apoptosis, cell cycle migration inhibition and downregulation of m-TOR/PI3K/Akt signalling pathway.

Cervical cancer greatly contributes to cancer-associated mortalities worldwide. The growing incidence of cervical cancer is of primary concern, and has signaled the need for multiple treatment options. Despite preliminary responses to chemotherapy and/or surgical interventions, the tumors consistently relapse.

LncRNA GAS5 suppresses ovarian cancer by inducing inflammasome formation.

Objective: Long non-coding RNA growth arrest-specific transcript 5 (lncRNA GAS5) is involved in various kinds of cancer. However, the role of lncGAS5 in the development of ovarian cancer remains unclear. In the current study, we explored the cellular mechanism and clinical value of lncRNA GAS5 in ovarian cancer.

Overexpression of miRNA-221 promotes cell proliferation by targeting the apoptotic protease activating factor-1 and indicates a poor prognosis in ovarian cancer.

MicroRNAs are a class of small non-coding, endogenous RNAs involved in cancer development and progression. MicroRNA-221 (mir-221) has been reported to have both an oncogenic and tumor-suppressive role in human tumors, but the role of miR-221 in ovarian cancer is poorly understood. In the present study, the expression levels of miR-221 and the apoptosis protease activating factor 1 (APAF1) protein in 63 samples of ovarian cancer tissues and the cell lines, IOSE25, A2780, OVCAR3, SKOV3 and 3AO were detected by quantitative reverse-transcription polymerase chain reaction (qRT-PCR) and western blot analysis, respectively.

Correlation between protein expression of FOXP3 and level of FOXP3 promoter methylation in recurrent spontaneous abortion.

Aim: The aim of this study was to investigate the level of Forkhead box P3 (FOXP3) promoter methylation and protein expression in recurrent spontaneous abortion and to elucidate the pathogenesis of unexplained recurrent spontaneous abortion (URSA).

Methods: We assessed a total of 56 URSA patients with a normal embryo, 24 recurrent spontaneous abortion (RSA) patients with an abnormal embryo (as control group 1), and 39 normal pregnant women (as control group 2). The expression of FOXP3 protein in deciduas was assessed through Western blot, and the level of FOXP3 promoter methylation was detected using bisulfite-assisted genomic sequencing polymerase chain reaction.

Genome comparison of the CSFV-GZ-2009 isolate (GenBank accession No.

Adenovirus-vectored shRNAs targeted to the highly conserved regions of VP1 and 2B in tandem inhibits replication of foot-and-mouth disease virus both in vitro and in vivo.

Foot-and-mouth disease is a highly contagious and economically important disease of cloven-hoofed animals. RNA interference (RNAi) can be used as a rapid and specific antiviral approach. It was shown that treatment with recombinant adenovirus (Ad(VP1-2B)) carrying shRNAs targeted to the VP1 and 2B genes of FMDV expressed in tandem had marked antiviral effects against FMDV both in IBRS-2 cells and guinea pigs.

Objective: To investigate the association between the functional polymorphisms of Foxp3 gene and unexplained recurrent spontaneous abortion (URSA).

Methods: PCR-restriction fragment length polymorphism (rs3761548, rs2294021) and PCR with sequence-specific primers (rs2232365, rs5902434) were used to detect four polymorphisms of Foxp3 in 146 URSA cases and 112 normal controls.

Results: (1) The frequencies of rs3761548A/C were 10.

Association between functional polymorphisms of Foxp3 gene and the occurrence of unexplained recurrent spontaneous abortion in a Chinese Han population.

Unexplained recurrent spontaneous abortion (URSA) is an alloimmune disease associated with the failure of fetal-maternal immunologic tolerance in which the regulatory T lymphocytes (Treg) play a pivotal role. It is well known that Forkhead box P3 (Foxp3) is a crucial regulatory factor for the development and function of Treg cells. It has also been established that deficiency of the Foxp3 gene suppresses the regulatory function of Treg cells.

Genetic diversity and positive selection analysis of classical swine fever virus isolates in south China.

Classical swine fever virus (CSFV) causes a highly contagious disease that leads to significant economic losses in the pig industry worldwide. However, there is a paucity of knowledge on the accurate genotyping of CSFV isolates in south China. This study genotyped the E2 gene of 14 CSFV strains isolated during 2008-2010 from domestic pigs in different districts of south China.
