The human ZNF268 gene was initially described as a gene associated with early human embryogenesis and was later implicated in human leukemia due to the identification of an alternatively splice form in leukemia patients. To systematically evaluate the correlation of ZNF268 with human hematological malignancy, expression of different alternatively spliced forms of ZNF268 mRNA in peripheral blood...
Background: DNA hypermethylation and instability due to inactivation mutations in Ten–eleven translocation 2 (TET2) is a key biomarker of hematological malignancies. This study aims at characterizing two intronic noncanonical splice-site variants, c.3954+5_3954+8delGTTT c.3954+5G>A. Methods: We used silico prediction tools, reverse transcription (RT)-PCR, Sanger sequencing on blood/bone marrow-...
This study was performed to evaluate nested polymerase chain reaction (PCR) and real-time PCR methods for detection of Strongyloides stercoralis in fecal samples compared with parasitological methods. A total of 466 stool samples were examined by conventional parasitological methods (formalin ether concentration [FEC] and agar plate culture [APC]). DNA was extracted using an in-house method, an...
BACKGROUND AFRIMS longitudinal dengue surveillance in Thailand depends on the nested RT-PCR and the dengue IgM/IgG ELISA. OBJECTIVE To examine and improve the sensitivity of the nested RT-PCR using a panel of archived samples collected during dengue surveillance. STUDY DESIGN A retrospective analysis of 16,454 dengue IgM/IgG ELISA positive cases collected between 2000 and 2013 was done to i...
Down regulation of KLK7 expression in breast tissues and identification of a novel spliced KLK7 mRNA
Background: Alternative splicing commonly occurs in cancer cells and many cancer specific splice variants have been reported as potential candidate biomarkers of the disease. We have studied human tissue Kallikrein 7 (KLK7) mRNA expression profile in breast cancer patients of our region. KLK7 is member of a multi-gene family consisting of 15 members (KLK1-KLK15). Methods: We optimized touch dow...
The standard methodology for titrating dengue viruses, the plaque assay, is slow, time consuming and relatively expensive. Other methods require machinery that may not be routinely accessible to all researchers, particularly those in developing nations. We therefore sought to develop a rapid, simplified semiquantitative polymerase chain reaction (PCR) methodology based on the use of a template ...
Background: Formation of secondary structure such as DNA hairpins or loops may influence molecular genetics methods and PCR based approaches necessary for genetic engineering, in addition to gene regulation. Materials and Methods: A polymerase chain reaction with splice overlap extension (SOE-PCR) was used to create fully synthetic 1F5 chimeric anti-CD20 heavy- and light-chain genes. The chi...
BACKGROUND It is clinically important to detect and type human papillomavirus (HPV) in a sensitive and specific manner. OBJECTIVES Development of a nested-polymerase chain reaction-restriction fragment length polymorphism (nested-PCR-RFLP) assay to detect and type HPV based on the analysis of L1 gene. METHODS Analysis of published DNA sequence of mucosal HPV types to select sequences of new...
