Methods: Flow cytometry (permeabization andstaining procedure with conjugated antibodies) wasused. Results: We observed that the expression of Fasprotein on CD4^+ T lymphocyte subset of CA patientswas significantly higher than that of healthy controls(P<0.01). Conclusions: Increased expression of Fas proteinon CD4^+ T lymphocyte subset may be a cause of de-creased percentage of CD4^+ T lymphocyte subset. Thisinduces the increased ratio of CD4^+/CD8^+.展开更多

[Method] Combined with PCR amplification, RACE (rapid amplification of cDNA ends) technique was employed to clone 14-3-3 gene from banana; then the amplified sequence was sequenced and homologically analyzed. [Result] A new cDNA homologous with 14-3-3 protein genes were obtained by RT-PCR and RACE ( rapid amplification of cDNA ends ) approaches. The full length of this cDNA was 866 bp encoding 197 amino acids. Alignment of deduced amino acid sequence with those from other plants revealed that the cDNA shared high homology with 14-3-3 protein genes from other plants, and was designated as Musa acuminata 14-3-3 gene (Ma-14-3-3d). Phylogenetic analysis reveals that Ma-14-3-3d has closer genetic relationship with those from monocotyledon species than those from other species. [Conclusion] Ma-14-3-3d belongs to the same lineage of 14-3-3 from monocotyledon.展开更多
