Clinical and Pathological Characteristics of Skin Cancer Patients at Southern Medical University, Guangzhou, China. reports: The incidence of skin cancer is increasing in China, yet large-scale clinical and pathological data from China remain scarce. A retrospective analysis was conducted of 648 histopathologically confirmed skin cancer cases diagnosed at the Dermatology Hospital, Southern Medical University from January 2020 to July 2023. Patient demographics, tumour distribution, histological subtypes, and treatment approaches were evaluated.

Clathrin-associated SCYL2 contributes to the activation of PI3K/AKT signaling and tumorigenesis through PTEN phosphorylation in adult T-cell leukemia/lymphoma. reports: Inactivation of PTEN by post-translational modifications causes aberrant amplification of the PI3K/AKT signaling pathway in many tumors. PTEN is a tumor suppressor phosphatase that is frequently phosphorylated at conserved serine/threonine residues (S380, T382, and T383 clusters) in the C-terminal tail of ATL and various solid cancer cells. Here, we identify SCY1-like protein 2 (SCYL2), with a protein kinase-like domain, as a novel PTEN-binding protein; however, the mechanism by which SCYL2 regulates PTEN phosphorylation remains unclear.

Evaluating the Relationship Between Programmed Death Ligand-1 (Clone: 22C3), Anaplastic Lymphoma Kinase (D5F3), and C-ros Oncogene 1 (OT11A1) Expression in Lung Adenocarcinoma. reports: Objective This study investigates the relationship between programmed death ligand-1 (PD-L1), anaplastic lymphoma kinase (ALK), and c-ros oncogene 1 (ROS1) expression in lung adenocarcinoma (ADC). Methods Sixty-two cases were analyzed for ALK, ROS1, and PD-L1 expression using immunohistochemistry. Statistical evaluations were performed using chi-square and Fisher's exact tests.

Warburg effect in B-cell lymphoma: A case report and proposed management plan. reports: The Warburg effect is a rare but often fatal condition in patients with malignancies. This phenomenon, known as type B lactic acidosis, is defined by lactatemia without tissue hypoxia or hypoperfusion, in contrast to type A lactic acidosis, which usually results from either or both. A male patient in his seventies with a newly diagnosed diffuse large B-cell lymphoma is admitted to the intensive care unit due to severe metabolic derangements with hypoglycemia and lactatemia.

Ddx3x regulates B-cell development and immunoglobulin rearrangement in mice reports: The X chromosome gene, DDX3X, is an ATP-dependent RNA helicase with roles in transcription, splicing, nuclear export, and translation. Loss of function mutations in DDX3X are linked to a variety of neoplasms, including B-cell lymphoma. We find that conditional homozygous deletion (Mb1-Cre) of Ddx3x in developing mouse B cells in female mice results in a complete absence of mature peripheral B cells associated with an absolute block at the pro-B cell stage of development in the bone marrow.

N-glycosylation engineering in chimeric antigen receptor T cells enhances anti-tumor activity reports: Chimeric antigen receptor (CAR) T cell therapy has had limited success in solid tumors, requiring novel enhancement strategies. Modifying the glycocalyx of CAR T cells is unexplored; we report on genome-editing of the MGAT5 gene to abolish human CAR T N-glycan poly-LacNAc modifications. This boosted tumor control in carcinoma and lymphoma models, for donors of whom the non-engineered CAR T cells largely failed in tumor control. This is a preprint and not peer reviewed.

Comparison of Nanopore with Illumina Whole Genome Assemblies of the Epstein-Barr Virus in Burkitt Lymphoma reports: Endemic Burkitt lymphoma (eBL) is one of the most prevalent cancer in children in sub-Saharan Africa, and while prior studies have found that Epstein-Barr virus (EBV) type and variation may alter the tumor driver genes necessary for tumor survival, the precise relationship between EBV variation and EBV-associated tumorigenesis remains unclear due to lack of scalable, cost-effective, viral whole-genome sequencing from tumor samples. This study introduces a rapid and cost-effective method of enriching, sequencing, and assembling accurate EBV genomes in BL tumor cell lines through a combination of selective whole genome amplification (sWGA) and subsequent 2-tube multiplex polymerase chain reaction along with long-read sequencing with a portable sequencer. The method was optimized across a range of parameters to yield a high percentage of EBV reads and sufficient coverage across the EBV genome except for large repeat regions. This is a preprint and not peer reviewed.

Expression patterns of fibroblast activation protein and extra-domain B fibronectin in canine malignant tumors. reports: Fibroblast activation protein (FAP) is involved in the extracellular matrix (ECM) remodeling and wound healing. Absent in most adult tissues, it is overexpressed by neoplastic cells and/or cancer-associated fibroblasts (CAFs) in several human malignancies. The extra Domain-B of fibronectin (EDB+FN) is a splice variant of fibronectin involved in angiogenesis and tissue remodeling, overexpressed by CAFs and cancer-associated vessels (CAVs) in many aggressive human tumors.
