METHODS: All 330 enrolled participants diagnosed with stage Ⅲc EOC were randomly divided into two groups that received YHJD or a placebo. The primary end point was health-related quality of life (HRQL) measured by the functional assessment of cancer therapy-ovary cancer (FACT-O) questionnaire. The secondary end point was progression-free survival (PFS)...

AB0 blood group antigens were discovered over a century ago; however, it is still important to study their role in development of various pathological conditions. Today it is known that antigenic determinants of this blood group are present not only on erythrocyte membrane but also on other cells and tissues: platelets, gastrointestinal epithelium and salivary glands, respiratory system cells. In the last decade, a large number of studies have appeared to reveal the relationship between a specific disease and blood group type, meta-analyses have been published...

HPV is a very common virus worldwide spread by direct contact and involved in male reproductive health-related diseases such as infertility, condyloma acuminatum, and penile cancer. The development of HPV vaccines has contributed to the effective prevention of various subtypes of HPV and protection of males from HPV infection, especially the partners of HPV-positive females, the men who have sex with men, and those with a psychological fear of HPV infection. Therefore, HPV vaccines play an important role in the protection of males...

Long non-coding RNAs (lncRNA) are a cluster of non-coding RNAs with a length of more than 200 nucleotides, which, formerly considered as "transcriptional noise" of DNA, have now been proved to be widely involved in the regulation of gene expressions and play pivotal roles in the proliferation, differentiation and apoptosis of cells and the development and progression of tumors. Recent studies show that a series of lncRNAs participate in the regulation of the progression of prostate cancer, including the transition of the cancer cells from hormone-sensitive to castration-resistant...

The androgen receptor signaling pathway is a key factor in the development and progression of prostate cancer. Aldo-keto reductases AKR1C1-AKR1C4 play an important role in the synthesis and metabolism of androgens in the body, and their expressions influence the androgen receptor signaling pathway and consequently the development and progression of prostate cancer. For the treatment of androgen-resistant prostate cancer, which cannot be cured currently, Chinese medicine and phytotherapy are receiving more and more attention for the mild, long-lasting and multi-target advantages of the small molecules of traditional Chinese medicine...

Objective: To explore the correlation between the rs4705342 gene mutation in the promoter region of the miR-143/ miR-145 cluster and the risk of PCa in the Chinese Han population. METHODS: We enrolled in this study 156 cases of PCa and 188 cancer-free controls. Using TaqMan SNP genotyping assay, we detected the polymorphism of rs4705342 in the promoter region of the miR-143/ miR-145 gene, and performed a stratified analysis on the family history of cancer, body mass index (BMI), age, smoking status, and alcohol consumption of the subjects...

In this study, we investigated the in vitro effect of tomentosin on cell proliferation by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, reactive oxygen species by 2',7'-dichlorofluorescein diacetate staining assay, apoptosis (AO/EtBr, propidium iodide, and 4',6-diamidino-2-phenylindole staining, mitochondrial membrane potential), cell adherent, cell migration, inflammation, apoptosis, and oxidative stress from gastric cancer cells (GCCs) AGS. Upon their relative cell proliferative, inflammatory, and apoptotic molecular markers were analyzed by using the enzyme-linked immunosorbent assay and Western blot analysis method...

Lysine-specific demethylase 1 (LSD1) has evolved as a promising therapeutic target for cancer treatment, especially in acute myeloid leukaemia (AML). To approach the challenge of site-specific LSD1 inhibition, we developed an enzyme-prodrug system with the bacterial nitroreductase NfsB (NTR) that was expressed in the virally transfected AML cell line THP1-NTR + . The cellular activity of the NTR was proven with a new luminescent NTR probe. We synthesised a diverse set of nitroaromatic prodrugs that by design do not affect LSD1 and are reduced by the NTR to release an active LSD1 inhibitor...

BACKGROUND: The objective of this study was to characterize the prevalence and risk of pain, pain interference, and recurrent pain in adult survivors of childhood cancer in comparison with siblings. METHODS: This study analyzed longitudinal data from survivors (n = 10,012; 48.7% female; median age, 31 years [range, 17-57 years]; median time since diagnosis, 23 years) and siblings (n = 3173) from the Childhood Cancer Survivor Study. Survivors were diagnosed between 1970 and 1986 at 1 of 26 participating sites...

Patients with advanced breast cancer (BC) showed a higher incidence of regional and distant metastases. Sine oculis homeobox homolog 1 (SIX-1) has been confirmed to be a key tumorigenic and metastatic regulator in BC progression. Yet, molecular mechanisms behind SIX-1-induced BC metastases remain largely unknown. Here we found that SIX-1 was frequently up-regulated in BC and correlated with poor outcomes when tested in human BC tissue microarray. Then, we manipulated the expression of SIX-1 by via shRNA-mediated knockdown and lentivirus-mediated overexpression...

Three new cadinane sesquiterpenes, trichodermaloids A (1), B (2), and C (5) were isolated from a symbiotic fungus Trichoderma sp. SM16 derived from the marine sponge Dysidea sp., together with three known ones, aspergilloid G (3), rhinomilisin E (4), and rhinomilisin G (6). The complete structures of three new compounds were determined by HR-MS and NMR spectroscopic analyses coupled with ECD calculations. The absolute configurations of two known compounds (4 and 6) were determined for the first time. The six isolates were inactive as antibacterial agents...

Gynaecologic and breast cancers share some similarities at the molecular level. The aims of our study are to highlight the similarities and differences about IDO1, an important immune-related gene in female cancers. The NGS data from TCGA of cervical squamous cell carcinoma (CESC), ovarian serous cystadenocarcinoma (OV), uterine corpus endometrial carcinoma (UCEC), uterine carcinosarcoma (UCS) and breast invasive carcinoma (BRCA) were analysed to identify molecular features, and clinically significant and potential therapeutic targets of IDO1...

The tripartite motif (TRIM) family proteins play a great role in carcinogenesis. However, the expression pattern, prognostic value and biological functions of tripartite motif containing 23 (TRIM23) in colorectal cancer (CRC) are poorly understood. Here, we found that TRIM23 is up-regulated and associated with tumour size, lymph node metastasis, American Joint Committee on Cancer (AJCC) stage and poor prognosis in CRC. Multivariate Cox regression analyses revealed that TRIM23 overexpression could be identified as an independent prognostic factor for CRC...

Healthcare disparities in genomic medicine are well described. Despite some improvements, we continue to see fewer individuals of African American, Asian, and Hispanic ancestry undergo genetic counseling and testing compared to those of European ancestry. It is well established that variant of uncertain significance (VUS) rates are higher among non-European ancestral groups undergoing multi-gene hereditary cancer panel testing. However, pathogenic variant (PV) yields, and genomic data in general, are often reported in aggregate and derived from cohorts largely comprised of individuals of European ancestry...

AIM: Lung cancer serves as one of the most common cancers in the world, and approximately 50% of non-small-cell lung cancer (NSCLC) patients are found to be aged >70 when diagnosed. In this study, we aimed to explore the effect of long non-coding RNAs colon cancer-associated transcript-1 (CCAT1) in NSCLC. METHODS: A total of 72 clinical samples from older NSCLC patients were collected for analysis. The relative mRNA level of CCAT1 was detected through real-time polymerase chain reaction...

Cancer risk assessment services are important for patient care; effective use requires appropriate provider referral, accurate scheduling processes, and completed attendance at booked appointments. Sociodemographic and clinical factors associated with gastrointestinal cancer (GIC)-specific risk assessment appointments remain unstudied; therefore, we aimed to identify factors associated with appointment completion in a GIC risk assessment program at a tertiary academic center. Retrospective chart review was conducted on all patients scheduled for an appointment in the Gastrointestinal Cancer Risk Evaluation Program (GI-CREP) between January 2016 and December 2017...
