ABSTRACT
Objective:To detect the expressions of survivin, galectin-3 and thyroid peroxidase in papillary thyroid microcarcinoma ( PTMC) and cancer adjacent normal tissue to explore the clinical significant.The correlations between the expressions of survivin,Gal-3 and TPO with BRAFV600E gene mutation in PTMC were analyzed.Methods: The expressions of survivin,Gal-3 and TPO were measured by immunohistochemical ( IHC ) method in 56 cases of PTMC tissue and adjacent normal tissue; BRAFV600E mutation was detected by PCR amplification and subsequently sequencing.Chi square test was used to analyse the relation in the expression rates of survivin,Gal-3 and TPO and BRAFV600E gene mutation.Results:The survivin and Gal-3 were strongly expressed but TPO was negatively expressed.The survivin and Gal-3 were negative in adjacent normal tissues but TPO was expressed.There were sig-nificant differences in the expression rates of survivin, Gal-3 and TPO between PTMC tissue and adjacent normal tissue (all P0.05).There were no correlation was found between the expressions of survivin,Gal-3,TPO and the BRAFV600E gene mutation in PTMC(all P>0.05).Conclusion: The strong expressions of survivin and Gal-3,the mild expression of TPO and BRAF mutation may be important in the development of PTMC,and the detection of BRAFV600E gene mutation and the expressions of survivin, Gal-3 and TPO could be used to the judgment of pathogenetic condition and prognostic outcomes.
ABSTRACT
Objective To clone and analyze the MN/CA9 gene sequence in ICR mice and detect the expressions of MN/CA9 gene in various tissues of ICR mice.Methods The fresh tissues of small intesine, uterrus, skin, musle, liver, pancreas, heart, lung, thymus, spleen, kidney, ovary, stomach ,urinary bladder from ICR mice were obtained , the total RNA was extracted by GIT method, the 1st strand and 2nd strand of cDNA were synthesized, the EcoRⅠ adapters were lingated,the EcoRⅠ ends were phosphorylated, digested with XhoⅠ ,cDNA was ligated into the ZAP expression vector, packaged, planted, screened.The expressions of MN/CA 9 gene in various tissues in mice were detected by RT-PCR.Results A fragment of human MN/CA9 gene was used as probe, and 1.47?10~3 clones were screened with radioactive isotopic ~ 32 P labeled probe, after hybridizations, one positive signal of cDNA was detected and the complete nucleotide sequence contained 1 671 bp was determined (GenBank:AB086322), The nucleotide similarity between mouse and human cDNA (GenBank:Z54349) was 69.1%.The MN/CA9 gene detected by RT-PCR assay (primer: P521-P1193) strongly expressed in small intesine,uterus, musle, pancreas, heart, lung, thymus, spleen, kidney, ovary, stomach,and urinary bladder,meanwhile did not express in skin and liver. Conclusion The expressions of MN/CA9 gene in some tissues of ICR mice are similar to that of human, it can be used to further functional analysis of MN/CA9 gene.
