False positives were eliminated by reverse Northern analysis. Positives were confirmed by Northern blot analysis. RESULTS: [1] Four of 69 cDNA fragments (3 up-regulated named L1, L2 and L3 and 1 down-regulated named Mi in leiomyoma) were confirmed by Northern analysis. [2] Sequence comparison and Northern analysis proved that Li is exactly the human ribosomal protein Si9. [3] It was present ubiquitously in i3 tissues tested but in various levels and even in different size. [4] Li was highly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. [5] No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPSi9 overexpression might be a universal signal in rapid cell growth tissues.展开更多
