Abstract
OBJECTIVES To find biochemical and molecular markers can assist in identifying serious liver damage of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) patients. METHODS 138 patients under 13 days to 1.1 year old diagnosed of NICCD in our center from 2004 to 2020. Base on the abnormal liver laboratory tests, we divided 138 patients into three groups: acute liver failure (ALF), liver dysfunction, and non-liver dysfunction groups, then compared their clinical, biochemical and, molecular data. RESULTS 96 % of 138 patients had high levels of citrulline and high ratio of threonine to serine, which is the distinctive feature of plasma amino acid profile for NICCD. A total of 18.1 % of 138 patients had evidence of ALF who presented the most severity hepatic damage, 51.5 % had liver dysfunction, and the remaining 30.4 % presented mild clinical symptoms (non-liver dysfunction). In ALF group, the levels of citrulline, tyrosine, TBIL, ALP, and γ-GT was significantly elevated, and the level of ALB and Fisher ratio was pronounced low. Homozygous mutations of 1,638_1660dup, IVS6+5G.A, or IVS16ins3kb in SLC25A13 gene were only found in ALF and liver dysfunction groups. Supportive treatment including medium-chain triglyceride supplemented diet and fresh frozen plasma could be life-saving and might reverse ALF. CONCLUSIONS High level of citrulline, tyrosine, TBIL, ALP, γ-GT, and ammonia, low level of albumin, and low Fisher ratio were predictors to suggest severe liver damage in NICCD patients who may go on to develop fatal metabolic disorder. Early identification and proper therapy is particularly important for these patients.

Abstract
Citrin deficiency is a pan-ethnic and highly prevalent mitochondrial disease with three different stages: neonatal intrahepatic cholestasis (NICCD), a relatively mild adaptation stage, and type II citrullinemia in adulthood (CTLN2). The cause is the absence or dysfunction of the calcium-regulated mitochondrial aspartate/glutamate carrier 2 (AGC2/SLC25A13), also called citrin, which imports glutamate into the mitochondrial matrix and exports aspartate to the cytosol. In citrin deficiency, these missing transport steps lead to impairment of the malate-aspartate shuttle, gluconeogenesis, amino acid homeostasis, and the urea cycle. In this review, we describe the geological spread and occurrence of citrin deficiency, the metabolic consequences and use our current knowledge of the structure to predict the impact of the known pathogenic mutations on the calcium-regulatory and transport mechanism of citrin.

Abstract
The kynurenine (Kyn) pathway plays crucial roles in several inflammation-induced disorders such as depression. In this study, we measured Kyn and other related molecules in the blood plasma, brain, and urine of male C57BL/6J mice (B6) fed non-purified (MF) and semi-purified (AIN-93G and AIN-93M) standard rodent diets. Mice fed MF had increased plasma Kyn levels compared with those on AIN93-based diets, as well as decreased hippocampal Kyn levels compared with those fed AIN-93G. Previous studies showed that branched chain amino acids (BCAAs) suppress peripheral blood Kyn transportation to the brain, but plasma BCAA levels were not significantly different between the diet groups in our study. Urine metabolome analysis revealed that feed ingredients affected the excretion of many metabolites, and MF-fed mice had elevated excretion of kynurenic and quinolinic acids, pivotal metabolites in the Kyn pathway. Collectively, the level of critical metabolites in the Kyn pathway in the central and peripheral tissues was strongly affected by feed ingredients. Therefore, feed selection is a critical factor to ensure the reproducibility of experimental data in studies involving rodent models.

Abstract
Energy metabolism in cancer cells is reprogrammed to meet the energy demands for cell proliferation under strict environments. In addition to the specifically activated metabolism of cancer, including the Warburg effect and glutaminolysis, most amino acids (AAs) are utilized for gluconeogenesis. Significant increases in AAs and energy metabolites in the tumor region occur in gastric and colon cancers. However, a different AA-related energy metabolism may exist in lung cancer because of the abundant blood supply to lung tissue. This study compared the profiles of AAs and their related metabolites in energy metabolism, analyzed by an HPLC-MS/MS system, between tissues from nontumor and tumor regions collected from 14 patients with non-small cell lung cancer (NSCLC). In the energic metabolism precursor categories, the glucogenic AAs, which included the pyruvate precursors (Ser, Gly, Thr, Ala, and Trp), the α-ketoglutarate precursors (Glu, Gln, and Pro) and the succinyl-CoA precursors (Val, Ile, and Met) were significantly increased in the tumor region compared to in the nontumor region. However, no significant differences existed between the two regions in the ketogenic AAs (Leu, Lys, and Tyr). These differences were not observed between the subgroups with and without diabetes mellitus in the two regions. The metabolites on the left-hand side of the TCA cycle were significantly higher in the tumor region, but no differences in metabolites in the right-hand side. The mRNA expressions of major AA transporters and cancer proliferation factors were also significantly increased in the tumor region, compared to these in their counterparts. In lung cancer, glucogenic AAs that are actively transported from circulating fluids would be predominantly utilized for gluconeogenesis, with and without diabetes mellitus. The characteristics of the AA-related metabolism would be associated with tissue-specific cell proliferation in patients with NSCLC.

Impaired bile acid metabolism with defectives of mitochondrial-tRNA taurine modification and bile acid taurine conjugation in the taurine depleted cats. Sci Rep 2020; 10:4915.

Abstract
Taurine that conjugates with bile acid (BA) and mitochondrial-tRNA (mt-tRNA) is a conditional essential amino acid in humans, similarly to cats. To better understand the influence of acquired depletion of taurine on BA metabolism, the profiling of BAs and its intermediates, BA metabolism-enzyme expression, and taurine modified mt-tRNAs were evaluated in the taurine deficient diet-supplemented cats. In the taurine depleted cats, taurine-conjugated bile acids in bile and taurine-modified mt-tRNA in liver were significantly decreased, whereas unconjugated BA in serum was markedly increased. Impaired bile acid metabolism in the liver was induced accompanied with the decreases of mitochondrial cholesterol 27-hydroxylase expression and mitochondrial activity. Consequently, total bile acid concentration in bile was significantly decreased by the low activity of mitochondrial bile acid synthesis. These results implied that the insufficient dietary taurine intake causes impaired bile acid metabolism, and in turn, a risk for the various diseases similar to the mitochondrial diseases would be enhanced.

Abstract
A 60-year-old male, who exhibited finger tremors, obnubilation, and hyperammonemia (409 μg/dL), was admitted to our hospital. Initially, we suspected that a portosystemic shunt had caused his hyperammonemia. However, his symptoms did not improve after balloon-occluded retrograde transvenous obliteration. He was subsequently found to have some peculiar eating habits, including a fondness for bean curd and peanuts, and an aversion to alcohol and sweets. Furthermore, marked citrullinemia (454.2 nmol/mL) was revealed, which led us to suspect adult-onset type II citrullinemia (CTLN2). DNA analysis of the patient and his mother, son, and daughter confirmed that he was homozygous for the c.852_855del mutation in the SLC25A13 gene, and his relatives were heterozygous for the c.852_855del mutation, which led to a definitive diagnosis. A low-carbohydrate diet and the administration of L-arginine ameliorated his symptoms. It is important to be aware that CTLN2 can occur in elderly patients. Thus, patients who exhibit symptoms of CTLN2 should be interviewed about their dietary habits and subjected to plasma amino acid analysis.In this report, we consider the metabolic disorders seen in citrin deficiency and the associated compensatory mechanisms in relation to the clinical features and treatment of CTLN2.

Abstract
Taurine content in the body is maintained by both biosynthesis from sulfur-contained amino acids in the liver and ingestion from usual foods, mainly seafoods and meat. Contrary to the rodents, the maintenance of taurine content in the body depends on the oral taurine ingestion in cats as well as humans because of the low ability of the biosynthesis. Therefore, insufficient of dietary taurine intake increases the risks of various diseases such as blind and expanded cardiomyopathy in the cats. One of the most established physiological roles of taurine is the conjugation with bile acid in the liver. In addition, taurine has effect to increase the expression and activity of bile acid synthesis rate-limiting enzyme CYP7A1. Present study purposed to evaluate the influence of taurine deficiency on bile acids in the cats fed taurine-lacking diet. Adult cats were fed the soybean protein-based diet with 0.15% taurine or without taurine for 30 weeks. Taurine concentration in serum and liver was undetectable, and bile acids in the bile were significantly decreased in the taurine-deficient cats. Taurine-conjugated bile acids in the bile were significantly decreased, and instead, unconjugated bile acids were significantly increased in the taurine-deficient cats. Present results suggested that the taurine may play an important role in the synthesis of bile acids in the liver.
