Abstract Background Long intergenic non-protein coding RNA 00342 (LINC00342) has been identified as a novel oncogene. However, the functional role of LINC00342 in colorectal cancer (CRC) remains unclear. Methods The expression is detected by real-time PCR (RT-PCR) analysis. Cell proliferation, migration and invasion xenograft model are examined to analyze biological functions vitro vivo using c...

A simple procedure for isolating yeast DNA suitable for use as a template for PCR amplification is described. SDS treatment alone is sufficient for extraction of chromosomal DNA from yeast cells. Cells of a yeast colony are suspended in a small volume (about 20 microL) of a 0.25% SDS solution, mixed vigorously and centrifuged. The supernatant can be directly used as a template after dilution to...

The literature lacks consensus on the minimum microbial density required for diagnosing urinary tract infections (UTIs). This study categorized densities of urine specimens from symptomatic UTI patients aged ≥ 60 years and correlated them with detected levels immune response biomarkers neutrophil gelatinase-associated lipocalin (NGAL), interleukin-8 (IL-8), interleukin-1-beta (IL-1β). objective...

BACKGROUND To understand the involvement of structural maintenance of chromosome 4 (SMC4) in the development and progression of hepatocellular carcinoma (HCC). METHODS Real-time quantitative PCR and Western Blotting were applied to measure the expression of SMC4 in HCC samples and cell lines. The tumor-promoting effect of SMC4 was determined by WST-1, soft agar colony formation, cell motility...

MATERIALS Taq DNA polymerase Marker DNA As a reference, use single-stranded DNA from the original bacteriophage M13 recombinant. MgCl2 (25 mM) Oligonucleotide primers The oligonucleotides should be 20-24 nucleotides in length, specific for the target DNA sequences, free of potential secondary structures, and contain no less than 10 and no more than 15 G and C residues. Yeast colony PCR buffer, ...

Direct colony polymerase chain reaction (DCPCR) is a useful molecular biological technique for application in the field of mycology. In this study, all of the 63 fungal strains examined, including those of the genera Candida and Aspergillus, were amenable to DNA amplification using an Ampdirect(R) Plus kit, which allows direct PCR amplification with no requirement for DNA extraction, following ...
