LncRNA UBE2R2-AS1, as prognostic marker, promotes cell proliferation and EMT in prostate cancer.

Background: Long noncoding RNA ubiquitin-conjugating enzyme E2 R2 antisense RNA 1 (UBE2R2-AS1) has been recently reported to participate in the progression of tumors, including glioma and liver cancer. However, the roles of UBE2R2-AS1 in prostate cancer (PC) remained poorly understood.

Methods: The expression of UBE2R2-AS1 was determined in tumor tissues and paired adjacent tissues from PC patients using quantitative reverse transcription PCR analysis.

Antimicrobial mexicanolide limonoids from the seeds of .

Three new mexicanolide limonoids were obtained from the 90% ethanol extract of the seeds of Their structures were elucidated as senegalenines AC () by analysing their 1D/2D NMR and MS spectroscopic analysis. In addition, the isolated limonoids were tested for antimicrobial potentials against 5 pathogenic microorganisms. Consequently, compounds exhibited antimicrobial activity against the tested Gram negative bacteria at the minimum inhibitory concentration values less than 40 μg/ml.

Upregulation of circular RNA circ_0000502 predicts unfavorable prognosis in osteosarcoma and facilitates cell progression via sponging miR-1238.

Growing evidence suggests that circular RNAs (circRNAs) play a significant role in regulating cancer initiation and metastasis. Osteosarcoma (OS) is a sophisticated disease with various genes activated or silenced. In this study, we defined a novel cancer-related circRNA, circ_0000502 in OS progression.

Cytotoxic and antibacterial aspidofractinine alkaloids from Kopsia hainanensis.

The ethanol extract of the twigs and leaves of Kopsia hainanensis afforded six new aspidofractinine alkaloids, kopsiahainanins A-F (1-6), among which alkaloids 1 and 2 possessed a lactone bridge with novel regiochemistry. The structures of the isolated compounds were established based on 1D and 2D (HH COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass spectrometry. The isolated compounds were tested in vitro for cytotoxic activity against seven tumor cell lines and antibacterial activities against two Gram-positive bacteria and five Gram-negative bacteria.

Upregulated long noncoding RNA LINC01296 indicates a dismal prognosis for pancreatic ductal adenocarcinoma and promotes cell metastatic properties by affecting EMT.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a fatal disease that responds poorly to chemotherapy and radiotherapy and whose incidence has increased worldwide. Long noncoding RNAs have been demonstrated to play important roles in cancer initiation and progression. Long intergenic non-coding RNA 01296 (LINC01296) has been reported to be upregulated in several malignancies, but the clinical relevance and biological role of LINC01296 in PDAC are still unclear.

A novel prognostic biomarker for pancreatic ductal adenocarcinoma: hsa_circ_0001649.

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with increasing incidence worldwide. Accumulating evidence indicated that circular RNAs (circRNAs) behave as a novel class of transcription products during multiple cancer processes. Specifically, hsa_circ_0001649 has been reported to be down-regulated in several cancers.

Enhanced expression of lncRNA TP73-AS1 predicts adverse phenotypes for cholangiocarcinoma and exerts oncogenic properties in vitro and in vivo.

Cholangiocarcinoma (CCA) is one of the most aggressive malignancies with increasing incidence worldwide. Various evidence documents that abnormally expressed long non-coding RNAs (lncRNAs) play important roles in tumorigenesis and progression. TP73-AS1 is a novel cancer-related lncRNA that contributes to the development of several malignancies.

An increased expression of long non-coding RNA PANDAR promotes cell proliferation and inhibits cell apoptosis in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignancies worldwide. Emerging evidence indicates that aberrantly expressed long non-coding RNAs (lncRNAs) act as imperative roles in tumorigenesis and progression. PANDAR (promoter of CDKN1A antisense DNA damage activated RNA) is a novel lncRNA that contributes to the development of various cancers.

Impact of Chemotherapy Delay on Overall Survival for AML with IDH1/2 Mutations: A Study in Adult Chinese Patients.

The effect of time from diagnosis to treatment (TDT) on overall survival of patients with acute myeloid leukemia (AML) remains obscure. Furthermore, whether chemotherapy delay impacts overall survival (OS) of patients with a special molecular subtype has not been investigated. Here, we enrolled 364 cases of AML to assess the effect of TDT on OS by fractional polynomial regression in the context of clinical parameters and genes of FLT3ITD, NPM1, CEBPA, DNMT3a, and IDH1/2 mutations.

An improved MLVF method and its comparison with traditional MLVF, spa typing, MLST/SCCmec and PFGE for the typing of methicillin-resistant Staphylococcus aureus.

Methicillin-resistant Staphylococcus aureus (MRSA) has become an important nosocomial pathogen, causing considerable morbidity and mortality. During the last 20 years, a variety of genotyping methods have been introduced for screening the prevalence of MRSA. In this study, we developed and evaluated an improved approach capillary gel electrophoresis based multilocus variable-number tandem-repeat fingerprinting (CGE/MLVF) for rapid MRSA typing.
