ESTs fragments which represents corresponding novel genes were obtained by sequencing and bioinformatics analysis of human fet al kidney cDNA library. Microarray was prepared by using these novel EST fragmen ts by automatic spotting. Expression patters of 79 ESTs of novel genes from huma n fetal kidney were analyzed in fetal brain and fetal heart tissues of 20\|week\ | and 26\|week\|age fetus by performing of cDNA chip hybridization. This provide s clues for studying exact functions of the novel genes. 8 genes were obtained w hich were expressed differentially in the fetal brain and heart of 20\|week\| an d 26\|week\|age respectively. Then differentially expressed genes were identifie d by Northern analysis. The more exact function of the novel genes is under stud y. 展开更多
