[IMAGE: molecular integration of the analysis of the human genome and its expression]

We have developed an integrated approach for the analysis of human cDNA libraries from neuromuscular tissues, based on the acquisition of primary structural, expression and mapping data. 26,938 sequence signatures (over 7 million bases) have been derived from both ends of skeletal muscle and brain cDNA clones. Primary redundancy analysis and classification of database similarities made it possible to characterize by structural data about 8,000 human gene transcripts, the majority of which is catalogued for the first time. Collecting hybridization signatures of complex cDNA probes derived from the tissues of origin to cDNA clones arrayed on high density filters provided a global and quantifiable view of the complexity and level of expression of the different transcripts. The development of 2,792 eSTS markers amplifiable by PCR defined the chromosomal localization of some 2,500 genes corresponding to the transcripts sequenced. The data collected are part of the corpus of the human gene transcript catalog and the genic map of the human genome.
