Up regulation of long non-coding RNAs BACE1 and down regulation of LINC-PINT are associated with CRC clinicopathological characteristics.

Background: Long non-coding RNAs (LncRNAs) are known to have regulatory consequences for aberrant gene expression in cancers. The aim of this study was to evaluate the expression levels of long non-encoding RNAs, BACE1 (β-secretase1) and LINC-PINT (Long Intergenic Non-Protein Coding RNA, P53 Induced Transcript), in colorectal cancer (CRC) with clinicopathological parameters.

Methods And Results: Bioinformatics analysis defining effectual signalling pathways Wnt.

ANRIL as a prognostic biomarker in colon pre-cancerous lesion detection via non-invasive sampling.

Long non-coding RNAs have been proposed as biomarkers for the detection, prevention and screening of various malignancies. In this study, two lncRNAs (ANRIL and BANCR) were assessed for biomarker application in the early detection of colorectal cancer (CRC) through stool specimen testing, as a non-invasive and cost-effective methodology. A total of 40 stool samples were collected from patients referred to the hospital with colorectal cancer or adenomatous polyps as pre-cancerous lesions; patients were diagnosed using colonoscopy and pathology reports were available.

The effective function of circular RNA in colorectal cancer.

Colorectal cancer (CRC) is the 3rd most common type of cancer worldwide. Late detection plays role in one-third of annual mortality due to CRC. Therefore, it is essential to find a precise and optimal diagnostic and prognostic biomarker for the identification and treatment of colorectal tumorigenesis.

An old dog and new tricks: Genetic analysis of a Tudor dog recovered from the Mary Rose wreck.

The Tudor warship the Mary Rose sank in the Solent waters between Portsmouth and the Isle of Wight on the 19th of July 1545, whilst engaging a French invasion fleet. The ship was rediscovered in 1971 and between 1979 and 1982 the entire contents of the ship were excavated resulting in the recovery of over 25,000 objects, including the skeleton of a small to medium sized dog referred to as the Mary Rose Dog (MRD). Here we report the extraction and analysis of both mitochondrial and genomic DNA from a tooth of this animal.

Influences of history, geography, and religion on genetic structure: the Maronites in Lebanon.

Cultural expansions, including of religions, frequently leave genetic traces of differentiation and in-migration. These expansions may be driven by complex doctrinal differentiation, together with major population migrations and gene flow. The aim of this study was to explore the genetic signature of the establishment of religious communities in a region where some of the most influential religions originated, using the Y chromosome as an informative male-lineage marker.

Geographical structure of the Y-chromosomal genetic landscape of the Levant: a coastal-inland contrast.

We have examined the male-specific phylogeography of the Levant and its surroundings by analyzing Y-chromosomal haplogroup distributions using 5874 samples (885 new) from 23 countries. The diversity within some of these haplogroups was also examined. The Levantine populations showed clustering in SNP and STR analyses when considered against a broad Middle-East and North African background.
