Article Synopsis
  • Familial hypercholesterolemia (FH) is a genetic disorder mainly caused by mutations in the LDLR gene, specifically identifying two pathogenic mutations: c.G1027A (p.Gly343Ser) and c.G1879A (p.Ala627Thr).
  • Whole exome sequencing was used to identify mutations in FH patients, followed by Sanger sequencing in their family members to analyze genetic correlations and evaluate LDLR expression using various cell assays.
  • Results showed p.Gly343Ser had normal protein localization, while p.Ala627Thr exhibited decreased expression and cytoplasmic localization, with bioinformatics indicating possible impacts on post-translational modifications affecting protein levels.

Article Synopsis
  • Alport syndrome (AS) is a genetic disorder leading to end-stage renal disease, often misdiagnosed, and the study focused on three Chinese families exhibiting nephrotic syndrome (NS) as a key symptom.
  • Genetic testing revealed three significant mutations in the COL4A5 gene associated with X-linked Alport syndrome, highlighting their role in causing kidney issues.
  • The findings suggest that some individuals may primarily present with nephrotic syndrome, expanding the understanding of how Alport syndrome manifests in patients.

Wasp venom injections from wasp stings can damage several organs, most commonly the kidneys. Despite literature evidence, wasp sting-induced acute kidney injury (AKI) is rare and involves complex pathophysiological processes. While acute tubular necrosis (ATN) is the most prevalent histological result of wasp sting-induced AKI, uncommon combinations of chronic renal lesions have been described, alerting us to the patient's underlying illness.

Background: Rotor syndrome (RS, OMIM#237450) is an extremely rare autosomal digenic recessive disorder characterized by mild non-hemolytic hereditary conjugated hyperbilirubinemia, caused by biallelic variation of and genes that resulted in OATP1B1/B3 dysfunction in the sinusoidal membrane leading to impaired bilirubin reuptake ability of hepatocytes.

Methods: One RS pedigree was recruited and clinical features were documented. Whole genome second-generation sequencing was used to screen candidate genes and mutations, Sanger sequencing confirmed predicted mutations.

Article Synopsis
  • - The study investigates a nonclassical form of Cholesterol Ester Storage Disorder (CESD) that appears to be inherited in an autosomal dominant manner, contrary to previous beliefs about it being autosomal recessive due to mutations in the LIPA gene, which affects lysosomal acid lipase (LAL) activity.
  • - Researchers analyzed a Chinese family with 15 members, finding that four living relatives displayed reduced LAL activity and liver dysfunction, while four deceased members likely died from liver failure linked to the disorder.
  • - Genetic analysis identified a new heterozygous mutation (c.1133T>C) in the LIPA gene among the living family members, suggesting a potential link between this mutation and the nonclass

  • - Gaucher disease (GD) is a rare genetic disorder caused by a deficiency of the enzyme glucocerebrosidase due to mutations in the GBA1 gene, resulting in symptoms affecting multiple organs, particularly the liver, spleen, and bone marrow.
  • - An adult male in China experienced severe splenic enlargement and related symptoms for 13 years, with his Gaucher disease diagnosis being delayed until a splenectomy revealed splenic Gaucher disease, highlighting the need for better awareness of rare diseases among healthcare providers.
  • - Genetic analysis identified two mutations in the GBA1 gene in the patient, including a previously unreported one, which may disrupt protein structure and contribute to his non-neuronopathic type of Gau

2,5-Dimethylpyrazine (2,5-DMP) is important pharmaceutical raw material and food flavoring agent. Recently, engineering microbes to produce 2,5-DMP has become an attractive alternative to chemical synthesis approach. In this study, metabolic engineering strategies were used to optimize the modified Escherichia coli BL21 (DE3) strain for efficient synthesis of 2,5-DMP using L-threonine dehydrogenase (EcTDH) from Escherichia coli BL21, NADH oxidase (EhNOX) from Enterococcus hirae, aminoacetone oxidase (ScAAO) from Streptococcus cristatus and L-threonine transporter protein (EcSstT) from Escherichia coli BL21, respectively.

Background: Prior research underscores the significant impact of remnant cholesterol (RC) on stroke occurrence due to its proatherogenic and proinflammatory traits. This study aims to explore diverse risks of new-onset stroke associated with RC, considering distinct inflammation levels in the middle-aged and senior population in China.

Methods: We analyzed 6509 participants from the China Health and Retirement Longitudinal Study (CHARLS) across four waves (2011-2018).

Mitochondria play multiple critical roles in cellular activity. In particular, mitochondrial translation is pivotal in the regulation of mitochondrial and cellular homeostasis. In this forum article, we discuss human mitochondrial tRNA metabolism and highlight its tight connection with various mitochondrial diseases caused by mutations in aminoacyl-tRNA synthetases, tRNAs, and tRNA-modifying enzymes.

Proofreading (editing) of mischarged tRNAs by cytoplasmic aminoacyl-tRNA synthetases (aaRSs), whose impairment causes neurodegeneration and cardiac diseases, is of high significance for protein homeostasis. However, whether mitochondrial translation needs fidelity and the significance of editing by mitochondrial aaRSs have been unclear. Here, we show that mammalian cells critically depended on the editing of mitochondrial threonyl-tRNA synthetase (mtThrRS, encoded by ), disruption of which accumulated Ser-tRNA and generated a large abundance of Thr-to-Ser misincorporated peptides in vivo.

Methyltransferase-like 8 (METTL8) encodes a mitochondria-localized METTL8-Iso1 and a nucleolus-distributed METTL8-Iso4 isoform, which differ only in their N-terminal extension (N-extension), by mRNA alternative splicing. METTL8-Iso1 generates 3-methylcytidine at position 32 (mC32) of mitochondrial tRNA and tRNA(UCN). Whether METTL8-Iso4 is an active mC32 methyltransferase and the role of the N-extension in mitochondrial tRNA mC32 formation remain unclear.

Background: Drug-eluting bead transarterial chemoembolization (DEB-TACE) has good efficacy in the treatment of unresectable hepatocellular carcinoma (uHCC), with a relatively high objective response rate (ORR) compared to conventional transarterial chemoembolization (cTACE). This study aimed to evaluate the safety and medium-term clinical efficacy of DEB-TACE combined with lenvatinib (LEN) plus PD-1 inhibitors as a triple therapy for the treatment of uHCC.

Methods: Data of patients with uHCC who received triple therapy of DEB-TACE combined with LEN plus PD-1 inhibitors from January 2019 to June 2021 were analyzed retrospectively.

  • * While Tars1 is essential for survival, as evidenced by lethal outcomes in Tars1 knockout mice, deleting Tarsl2 in mice and zebrafish showed no impact on tRNA levels or mRNA translation efficiency.
  • * The study found that Tarsl2 mutants experienced severe developmental issues and metabolic changes, indicating that even though Tarsl2 may have some activity, it is not vital for protein synthesis but significantly affects overall development in organisms.

Background: Behçet's disease (BD) is a unique autoimmune chronic systemic vasculitis that affects veins and arteries of all sizes. BD can lead to recurrent vascular events, especially venous thrombosis, with an incidence rate of 40%, or pseudoaneurysms formed under long-term inflammatory reaction or iatrogenic stimulation. BD-related risk factors promote endothelial dysfunction, platelet activation and overactivation of tissue factors leading to mural inflammatory thrombi.

To calculate the transverse-momentum-dependent parton distribution functions (TMDPDFs) from lattice QCD, an important goal yet to be realized, it is crucial to establish a viable nonperturbative renormalization approach for linear divergences in the corresponding Euclidean quasi-TMDPDF correlators in large-momentum effective theory. We perform a first systematic study of the renormalization property of the quasi-TMDPDFs by calculating the relevant matrix elements in a pion state at five lattice spacings ranging from 0.03 fm to 0.
