Nasophryngeal carcinoma

Dan-sheng Lei, Jing Yu, Xian-li Tong, Ming-wei Wang, Kun Wang, Hu Chen
OBJECTIVE: To explore the clinical significance of cytokeratin 19 fragments test in the diagnosis of nasopharyngeal carcinoma. METHODS: The study included 102 cases of nasopharyngeal carcinoma, 90 cases of nasal polyp/nasopharyngitis, and 150 healthy individuals. RT-PCR was used to detect CK19 mRNA expression and Western blot to detect CK19 fragment protein expression in tissues of nasopharyngeal carcinoma. Expression of CK19-2G2 was examined by immunohistochemistry...

OBJECTIVE: To clone A73 gene of Epstein-Barr virus (EBV) and examine the variation of its coding sequence. METHODS: A73 coding sequence (CDS) amplified from 7 patients in nasophryngeal carcinoma (NPC) biopsies by RT-PCR was cloned into pGEM-T-Easy vector to construct the recombinant plasmid, which was subjected to sequence analysis in Gen Bank database using Blast software. RESULTS: A73 gene from nasophryngeal carcinoma was successfully cloned into pGEM-T Easy vector...

The authors investigated the possibility of using PCR to dsetect the deletion of gene or loss of heterozygosity (LOH) of gene in biopsies. With some aids, such as selection of PCR cycle number, choice of internal control and screening of samples, the authors detected the deletion of GSH Clone 7 in nasophryngeal carcinoma (NPC) by PCR-Southern, and successfully found one case which partially deleted GSH Clone 7. This results was confirmed by image densitometry. Through this study, an available method to detect the deletion of gene by PCR is provided...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
