Phylogeny and Genetic Divergence among Sorghum Mosaic Virus Isolates Infecting Sugarcane.

Sorghum mosaic virus (SrMV, the genus of the family ) is a causal agent of common mosaic in sugarcane and poses a threat to the global sugar industry. In this study, a total of 901 sugarcane leaf samples with mosaic symptom were collected from eight provinces in China and were detected via RT-PCR using a primer pair specific to the SrMV coat protein (). These leaf samples included 839 samples from modern cultivars ( spp.

Lanostane triterpenoids with anti-proliferative and PTP1B/α-glucosidase inhibitory activities from the fruiting bodies of Ganoderma calidophilum.

Twelve previously undescribed and four known lanostane triterpenoids were isolated from the fruiting bodies of Ganoderma calidophilum. The structures of undescribed compounds, ganodecalones H-S (1-12), were elucidated by extensive spectroscopic analysis as well as ECD and NMR calculations. Compound 4 showed significant inhibitory activity against human leukaemia cell line K562, gastric cancer cell line SGC-7901, and cervical cancer cell line HeLa with IC values of 13.

Comparative genomics reveals insights into genetic variability and molecular evolution among sugarcane yellow leaf virus populations.

Yellow leaf disease caused by sugarcane yellow leaf virus (SCYLV) is one of the most prevalent diseases worldwide. In this study, six near-complete genome sequences of SCYLV were determined to be 5775-5881 bp in length. Phylogenetic analysis revealed that the two SCYLV isolates from Réunion Island, France, and four from China were clustered into REU and CUB genotypes, respectively, based on 50 genomic sequences (this study = 6, GenBank = 44).

Genetic Variability and Molecular Evolution of Maize Yellow Mosaic Virus Populations from Different Geographic Origins.

Maize yellow mosaic virus (MaYMV) hosted in various gramineous plants was assigned to the genus (family ) in 2018. However, little is known about its genetic diversity and population structure. In this study, 509 sugarcane leaf samples with mosaic symptoms were collected in 2017 to 2019 from eight sugarcane-growing provinces in China.

Prognostic value of urokinase plasminogen activator system in non-small cell lung cancer: A systematic review and meta-analysis.

Current relevant research suggests there are significant differences between the expression of the urokinase plasminogen activator (uPA) system in cancer tissues and in normal tissues. However, the potential effectiveness of the uPA system as a prognostic biomarker of non-small cell lung cancer (NSCLC) remains unclear. In the present study, a systematic review and meta-analysis were performed to evaluate the relevance of the uPA system in the prognosis of patients with NSCLC.

High mobility group box 1 protein is methylated and transported to cytoplasm in clear cell renal cell carcinoma.

Background: The high mobility group box 1 (HMGB1) protein is a widespread nuclear protein present in most cell types. It typically locates in the nucleus and functions as a nuclear cofactor in transcription regulation. However, HMGB1 can also localize in the cytoplasm and be released into extracellular matrix, where it plays critical roles in carcinogenesis and inflammation.

MicroRNAs in androgen-dependent PCa.

Prostate cancer (PCa) is the most commonly diagnosed cancer among men in Western countries and is one of the leading causes of cancer deaths. The growth and progression of PCa is related to androgen levels. In cancer, nicroRNAs (miRs) function as either oncogenes or tumor suppressor genes.

Tumor-infiltrating regulatory T cells are positively correlated with angiogenic status in renal cell carcinoma.

Background: Immune cells within a tumor microenvironment have shown modulatory effects on tumor angiogenic activity. Renal cell carcinoma (RCC) is a hypervascular tumor that reportedly increases the frequency of regulatory T cells (Tregs) in tumor tissues. This study investigated the correlation between Tregs infiltration and angiogenic status in RCC.

Distribution of serum prostate-specific antigen in Chinese healthy men: a population-based study.

Background: The morbidity and mortality of prostate cancer have been increasing rapidly in recent China. There were few studies investigating prostate-specific antigen (PSA) values ranges in the healthy Chinese population. We performed this study to determine the distribution of serum PSA in a large healthy Chinese population.

[Total PSA, PSA density and biopsy Gleason score in predicting the pathologic stage of prostate cancer].

Objective: To evaluate the roles of total prostate specific antigen (tPSA), PSA density (PSAD) and biopsy Gleason score in predicting the pathologic stage of prostate cancer.

Methods: We retrospectively analyzed the clinical data of 124 cases of pathologically confirmed prostate adenocarcinoma, and divided them into Groups A (n=48) and B (n=76) based on the results of bone scanning, CT, MRI, tPSA, PSAD and postoperative biopsy Gleason score, the former with extraprostatic infiltration or distant metastasis, while the latter without. We compared the above parameters between the two groups, screened the main factors that influenced the pathologic staging of prostate cancer by multivariate logistic regression analysis, and appraised the value of each of the parameters in predicting the pathologic stage of prostate cancer with a relative operating characteristic (ROC) curve.

Expression of p53 isoforms in renal cell carcinoma.

Background: Several isoforms of p53 have been reported, which may have varying functions and expressions. This study aimed to analyze the expression patterns of p53 isoforms in renal cell carcinoma (RCC) at the mRNA and protein levels and their associations with clinical and pathologic factors to explore the mechanism of p53 isoforms' activity in RCC.

Methods: The specimens of tumours (T) and clinically normal tissues (N) adjacent to them were collected from 41 patients with RCC.

Comparison of tamsulosin with extracorporeal shock wave lithotripsy in treating distal ureteral stones.

Background: Tamsulosin, an alpha-1 receptor antagonist, has been demonstrated effective in promoting distal ureteral stone passage and in reducing pain associated with stone expulsion. This study aimed to evaluate the effect of tamsulosin in comparison with nifedipine and extracorporeal shock wave lithotripsy (ESWL) on the expulsion rate of distal ureteral stones at different sizes.

Methods: We assigned 314 patients to three categories: I, the stone with maximal diameter of 4.

Impact of human leukocyte antigen matching and recipients' panel reactive antibodies on two-year outcome in presensitized renal allograft recipients.

Background: Renal transplantation in sensitized candidates remains a highly significant challenge worldwide. The production of panel reactive antibody (PRA) against human leukocyte antigen (HLA) is a major risk factor in presensitized recipients. The aim of this study was to evaluate the impact of HLA matching and recipients' PRA on two-year outcome in presensitized renal allograft recipients.

Dexamethasone suppresses DU145 cell proliferation and cell cycle through inhibition of the extracellular signal-regulated kinase 1/2 pathway and cyclin D1 expression.

Aim: To determine the mechanisms of glucocorticoids in inhibiting advanced prostate cancer growth.

Methods: The cell proliferation and cell cycle of prostate cancer DU145 cells following dexamethasone treatment were determined by proliferation assay and fluorescence-activated cell sorter.
