The Future of Biomarkers and Genomics

lncrna

from UroToday.com by  Zachary Klaassen, – Professor Manfred Wirth from Germany provided an update on the future of biomarkers and genomics at this afternoon’s EAU Update in Prostate Cancer in Vienna, Austria. Dr. Wirth divided his presentation into three subsections: Why are biomarkers needed for prostate cancer? There are several reasons according to Dr. Wirth why biomarkers are needed for prostate cancer, ...

Researchers hypothesize that the prostate-specific lncRNA PCA3 has been introduced into the human genome by an ancient virus

Prostate cancer, the most frequent type of cancer in men, is surpassed only by lung cancer in causing cancer-related death. Despite major progress in defining the mutational landscape of this tumor, its etiology remains obscure. The intronic long-noncoding RNA (lncRNA) PCA3 is a specific marker of prostate cancer that acts as a trans-dominant negative oncogene to down-regulate the tumor suppressor ...

The prognostic value of long noncoding RNAs in prostate cancer

lncRNA

The abnormally expressed LncRNAs played irreplaceable roles in the prognosis of prostate cancer (PCa). Therefore, researchers from Wuhan University conducted this systematic review and meta-analysis to summarize the association between the expression of LncRNAs, prognosis and clinicopathology of PCa. 18 eligible studies were recruited into their analysis, including 18 on prognosis and 9 on clinicopathological features. Results indicated that aberrant ...

Dietary anti-cancer compound may work by influence over lncRNAs

lncRNA

Researchers have discovered one of the reasons why broccoli may be good for your health.  They found that sulforaphane, a dietary compound from broccoli that’s known to help prevent prostate cancer, may work through its influence on long, non-coding RNAs. This is another step forward in a compelling new area of study on the underlying genetics of cancer development and ...

A panel of four-long noncoding RNA signatures predicts prostate cancer survival

lncRNA

Growing evidences showed that lncRNAs abnormally expressed in cancer tissues and played irreplaceable roles in tumorigenesis, progression and metastasis. In present study, researchers from Yangzhou University aimed to identify lncRNA expression signature that can predict biochemical recurrence-free (BCR-free) survival of prostate cancer (PCa) patients. A total of 291 patients with pathologic confirmed PCa in The Cancer Genome Atlas dataset were ...

Chemicals from the diet can influence the expression of functionally important lncRNAs

lncrna

Long noncoding RNAs (lncRNAs) have emerged as important in cancer development and progression. The impact of diet on lncRNA expression is largely unknown. Sulforaphane (SFN), obtained from vegetables like broccoli, can prevent and suppress cancer formation. Here researchers at Oregon State University tested the hypothesis that SFN attenuates the expression of cancer-associated lncRNAs. They analyzed whole-genome RNA-sequencing data of normal ...

LncRNAs and miRNAs – potential biomarkers and therapeutic targets for prostate cancer

Prostate cancer (PCa) is the second lethal disease for men in western countries. Although androgen receptor (AR) signaling has been widely investigated, noncoding RNAs (ncRNAs), deficient of open reading frame, have also received considerable attention. Growing studies showed that the aberrant ncRNAs expression contributed to cell proliferation, metastasis and drug resistance in PCa. Therefore, therapeutically targeting ncRNAs may synergize androgen ...

MALAT1 and HOTAIR Long Non-Coding RNAs Play Opposite Role in Prostate Cancer Cells

In the complex network of nuclear hormone receptors, the long non-coding RNAs (lncRNAs) are emerging as critical determinants of hormone action. Here researchers from the Institute of Cell Biology and Neurobiology, Rome investigated the involvement of selected cancer-associated lncRNAs in Estrogen Receptor (ER) signaling. Prior studies by Chromatin Immunoprecipitation (ChIP) Sequencing showed that in prostate cancer cells ERs form a ...

Risk-associated SNPs promote prostate cancer through modulating lncRNA expression

Long noncoding RNAs (lncRNAs) represent an attractive class of candidates to mediate cancer risk. Through integrative analysis of the lncRNA transcriptome with genomic data and SNP data from prostate cancer genome-wide association studies (GWAS), researchers at the Princess Margaret Cancer Center identified 45 candidate lncRNAs associated with risk to prostate cancer. They further evaluated the mechanism underlying the top hit, ...

PCAT14 is a Prognostic Biomarker in Prostate Cancer

lncRNA

Rapid advances in the discovery of long noncoding RNAs (lncRNAs) have identified lineage- and cancer-specific biomarkers that may be relevant in the clinical management of prostate cancer (PCa). Here University of Michigan researchers assembled and analyzed a large RNA-seq dataset, from 585 patient samples, including benign prostate tissue and both localized and metastatic PCa to discover and validate differentially expressed ...
