OBJECTIVETo analyze the characteristics of germline mutations of adenomatous polyposis coli (APC) gene in pedigrees affected with familial adenomatous polyposis (FAP).

METHODSGenomic DNA was extracted from peripheral blood samples from members of the 13 FAP pedigrees. Multiplex ligation-dependent probe amplification (MLPA) was used to detect large fragment deletions of the APC gene. Subsequently, potential mutation was screened from all exons of the APC gene with PCR amplification and direct sequencing.

RESULTSGermline mutations have been identified in 5 FAP pedigrees, which included c.3184_3187delCAAA, c.5432C>T, c.3925_3928delAAAA and c.3925_3929del AAAAG(in two pedigrees). Small deletional mutations were found primarily in the area of AAAAG tandem repeat sequences.

CONCLUSIONC.3925_3929 located in AAAAG tandem repeats is probably the hot spot for APC gene mutations, which are mostly deletional mutations, especially the 5 bp base deletion at codon 1309.

Objective To investigate the effect of type 2 dengue virus(DENV-2)infection on autophagy in human umbilical vein endothelial cells(HUVECs)and the mechanism mediating the inhibitory effect of baicalin against DENV-2 infection.Methods Cultured HUVECs with DENV-2 infection were treated with different concentrations of baicalin,and the changes in autophagy of the cells were detected using transmission electron microscopy.Lyso Tracker Red staining was used to examine pH changes in the lysosomes of the cells,and the expressions of ATG5,beclin-1,LC3,P62,STX17,SNAP29,VAMP8,and PI3K/AKT signaling pathway-related proteins were detected by Western blotting.DENV-2 replication in the cells were evaluated using RT-qPCR.The differentially expressed proteins in DENV-2-infected HUVECs were identified by proteomics screening.Results Treatment with baicalin did not significantly affect the viability of cultured HUVECs.Proteomic studies suggested that the PI3K-AKT pathway played an important role in mediating cell injury induced by DENV-2 infection.The results of RT-qPCR demonstrated that baicalin dose-dependently inhibited DENV-2 replication in HUVECs and produced the strongest inhibitory effect at the concentration of 50 μg/mL.Transmission electron microscopy,Lyso Tracker Red staining,RT-qPCR,and Western blotting all showed significant inhibitory effect of baicalin on DENV-2-induced autophagy in HUVECs.DENV-2 infection of HUVECs caused increased cellular expressions of LC3 and P62 proteins,which were significantly lowered by treatment with LY294002(a PI3K inhibitor).Conclusion Baicalin inhibits DENV-2 replication in HUVECs and suppresses DENV-2-induced cell autophagy by inhibiting the PI3K/AKT signaling pathway.
