Background and Aims:We asked if comprehensive bile acid profiling could provide insights into the physiopathology of ABCB4-mutated patients and evaluated the prognostic value of taurine-conjugated tetrahydroxylated bile acid(tauro-THBA)in ***:Serum bile acid profiles were evaluated in 13 ABCB4-mutated patients with 65 healthy controls by ultra-high-performance liquid chromatography/multiple-reaction monitoring-mass spectrometry(UPLC/MRM-MS).The concentration of tauro-THBA was compared between ABCB4-mutated patients with different *** areas under the curve(AUCs)of tauro-THBA were compared between ABCB11-mutated patients with native liver survival and those who died or underwent liver transplantation before 3 years of age by receiver operating characteristic curve(ROC),with another patient cohort for further ***:The overall hydrophobicity indices of bile acids in ABCB4-mutated patients(12.99±3.25 m)were significantly lower than those of healthy controls(14.02±1.74 m,p<0.000).That was due to markedly increased bile acid modifications including conjugation,sulfation,and *** in the tauro-THBA concentration in ABCB4-mutated patients with different prognoses were not *** analysis indicated that levels of tauro-THBA of<60 nM yielded an AUC of 0.900 with a sensitivity of 80%and specificity of 87.5%for ABCB11-mutated patients with different prognoses(p=0.0192).Of the 15 patients with good prognosis,14 were classified correctly and four of the five patients with a poor prognosis were classified correctly(14:15 vs.1:5,p=0.005)with tauro-THBA as a ***:Tauro-THBA concentration may be a biomarker for predicting the clinical outcome in low gammaglutamyl transferase intrahepatic cholestasis patients.

Amyotrophi c lateral s c lerosis(ALS)and frontotemporal dementia(FTD)are two closely related disorders with overlapping clinical,genetic,and neuropathological features,forming a continuous disease spectrum(Ling et al.,2013).The major pathological hallmark of ALS and FTD are the depletion from the nucleus of the RNA-binding proteins TAR DNA‐binding protein 43(TDP-43)and FUsed in Sarcoma(FUS)and their abnormal accumulation in ubiquitin-positive cytoplasmic inclusions(Ling et al.,2013).
