He isolated cet-1 null mutant by Tc1 deletion method. cet-1 nullmutants have shortened bodies and male tail abnormal phenotype resembling sma mutants.

Interestingly, CET-1 appears to affect body length in a dose dependent manner. Heterozygotes for cet-1 displayed body lengths ranging between null mutant and wild type, and overexpression of CET-1 in wild type worms elongated body length close to Jon mutants. Furthermore, his results show that cet-1 controls body length not proportionally but in two particular regions of the worm probably by changing cell volume. Moreover, genetic interaction of the cet-1 with mutants of the other TGF- β pathway in C. elegans, daf demonstrated that cet-1 is also involved at least partly in the daf signaling pathway. In male sensory ray patterning, lack of cet-1 function results in ray fusions. Epistasis analysis revealed that mab-21 lies downstream and is negatively regulated by the cet-1/sma pathway in the male tail. His results show that cet-1 controls diversed biological processes during C. elegans development probably through different target genes.\u003cbr /\u003e He also has identified two genes, CeBRAM-1A and CeBRAM-2B, which are similar to human BRAM-1 previously identified as a BMP receptor associated molecule, in C. elegans. The C. elegans BRAMs (CeBRAM-1A and CeBRAM-2B) show significant amino acid identity with human BRAM-1, particularly in the C-terminal region. CeBRAM-1A was found to associate with DAF-1, the type I receptor in the daf pathway in C elegans as well as a vertebrate BMP type I receptor BMPRIA. CeBRAM-1A::GFP fusion protein is expressed mainly in amphid neurons such as ASK, ASH, and ASG etc, where DAF-1 is expressed. Loss-of-function of CeBRAM-1A gene showed that the mutant worms looked normal except that they showed a behavior of head-lifting phenotype. Genetic interaction of CeBRAM-1A with previously known daf-7 TGF-β pathway mutants revealed that CeBRAM-1A negatively regulates the daf-7 TGF-β pathway and functions between daf-1 type I receptor and daf-14 SMAD. On the other hand, CeBRAM-2B::GFP fusion protein was expressed strongly in pharyngeal muscle and intestinal cells. This expression pattern of CeBRAM-2B is similar to that of sma-6 type I receptor of the cet-1/sma pathway. Interestingly, double strand RNA interference (dsRNAi) of CeBR,AM-2B showed Lon phenotype. These results strongly suggest that CeBRAM-1A and CeBRAM-2B may function as negative regulators of two distinct TGF-β signal pathways, the daf pathway and the sma pathway respectively in C. elegans.
