Macroautophagy (hereafter autophagy) initiates at the phagophore assembly site (PAS), where most of the AuTophaGy-related (Atg) proteins are at least transiently localized. As the first protein complex targeted to the PAS, the Atg17-Atg31-Atg29 complex serves as the scaffold for other Atg proteins and plays a critical role for the organization of the PAS, and in autophagy initiation. We recently showed that this complex is constitutively formed and activated by the phosphorylation of Atg29 when autophagy is induced. Phosphorylation of Atg29 is required for its interaction with Atg11, another scaffold protein, and its function for promoting the proper assembly of the PAS. Single-particle electron microscopy analysis of the Atg17-Atg31-Atg29 complex reveals an elongated structure with Atg29 located at the opposing ends. This structural arrangement allows Atg29 to interact with Atg11, and is critical in the organization of the intact Atg1 complex.

Characterization of Complete Mitochondrial Genome and Phylogeny of Three Echeneidae Species.
Animals (Basel)
January 2025
Fisheries College, Zhejiang Ocean University, Zhoushan 316022, China.
Article Synopsis
- Species in the Echeneidae family are known for their ability to attach to hosts using a sucking disc; this study analyzed the mitochondrial genomes of three such species.
- The mitochondrial genomes varied slightly in length and contained essential genes for protein coding, rRNA, tRNA, and a D-loop region, with most genes demonstrating specific patterns in their codon usage and genetic structure.
- Phylogenetic analysis revealed distinct relationships among the species, with one species forming its own group and the others being closely related, thus adding valuable data to the understanding of this fish family's classification.
Real-world cost-effectiveness analysis of thymoglobulin versus no induction therapy in kidney transplant recipients at low risk of graft loss.

Background: A new induction therapy strategy of a single 3 mg/kg dose of rabbit antithymocyte globulin (r-ATG) showed a lower incidence of acute rejection.
Methods: The objective of this study was to use real-world data to determine the incremental cost-effectiveness ratio (ICER) of r-ATG induction for the prevention of acute rejection (AR) in the first year following kidney transplantation and for kidney graft survival over 1, 4, and 10 years of post-transplantation from the perspective of the national public healthcare system. A Markov state transition model was developed utilizing real-world data extracted from medical invoices from a single center.

HIV-1 subtype C viruses are responsible for 50% of global HIV burden. However, nearly all currently available reporter viruses widely used in HIV research are based on subtype B. We constructed and characterized a replication-competent HIV-1 subtype C reporter virus expressing mGreenLantern.

Head lice infestation (HLI), caused by De Geer, 1767, has long been a common global problem of school children. Permethrin is an old pyrethroid derivative that has been used commonly for its treatment, and it exerts its activity over the voltage-sensitive calcium channels (VSCC) of the lice. There has been a growing list of persistent HLI cases lately in the world among patients using permethrin, and knockdown resistance (kdr)-related point mutations on VSCC have been identified and reported from those resistant lice samples.

This study examined the response to cisplatin in BxPC-3, Mia-Paca-2, PANC-1, and YAPC pancreatic cancer lines with different genotypic and phenotypic characteristics, and the mechanisms associated with their resistance. BxPC-3 and MIA-PaCa-2 cell lines were the most sensitive to cisplatin, while YAPC and PANC-1 were more resistant. Consistently, in cisplatin-treated BxPC-3 cells, the cleavage patterns of pro-caspase-9, -7, -3, and PARP-1 demonstrated that they were more sensitive than YAPC cells.
