The ultrastructure of two lymphoblastoid cell lines derived from Marek's disease lymphomata has been studied. The cells varied from 5 to 12 mum in diameter and had large round or oval nuclei. A nucleolus was occasionally present and about 3% of cells showed projections of the nuclear envelope. The cytoplasm contained many ribosomes and several mitochondria but endoplasmic reticulum was sparse. A small number of cells contained annulate lamellae and crystalline structures were occasionally seen. Cells with immature intranuclear herpesvirus particles were rarely present. The cells had many ultrastructural features in common with Burkitt's lymphoma-derived cell lines.

GNA15 induces drug resistance in B cell acute lymphoblastic leukemia by promoting fatty acid oxidation via activation of the AMPK pathway.
Mol Cell Biochem

Department of Hematology, The First Affiliated Hospital of Chongqing Medical University, Chongqing, 400016, China.
The prognosis of B cell acute lymphoblastic leukemia (B-ALL) is poor, primarily due to drug resistance and relapse. Ga15, encoded by GNA15, belongs to the G protein family, with G protein-coupled receptors playing a crucial role in multiple biological process. GNA15 has been reported to be involved in various malignancies; however, its potential role in B-ALL remain unknown.

Purpose: Identifying prognostic indicators for risk stratification in metastatic renal cell carcinoma (mRCC) is crucial for optimizing treatment strategies and follow-up plans. This study aims to investigate the prognostic role of the glucose-to-lymphocyte ratio (GLR) in patients with mRCC receiving tyrosine kinase inhibitors (TKIs) as first-line therapy.
Methods: A retrospective cohort study was conducted using data from the Turkish Oncology Group Kidney Cancer Consortium Database.

In this study, firstly chitin was reacted with chloracetyl chloride to synthesize the macroinitiator chitinchloroacetate (Ch.ClAc). Then, graft copolymers of methacrylamide (MAM), diacetone acrylamide (DAAM), N-(4-nitrophenyl)acrylamide (NPA), and 2-hydroxyethyl methacrylate (HEMA) monomers were synthesized by atom transfer radical polymerization (ATRP).

Background: Exosomes are extracellular vesicles released by cells that mediate intercellular communication and actively participate in cancer progression, metastasis, and regulation of immune response within the tumour microenvironment. Inhibiting exosome release from cancer cells could be employed as a therapeutic against cancer.
Methods And Results: In the present study, we have studied the effects of Acorus calamus in inhibiting exosome secretion via targetting Rab27a and neutral sphingomyelinase 2 (nSMase2) in HER2-positive (MDA-MB-453), hormone receptor-positive (MCF-7) and triple-negative breast cancer (MDA-MB-231) cells.

CAR-T cell therapies have risen to prominence over the last decade, and their indications are increasing with several products approved as early as second line in Large B Cell non-Hodgkin Lymphomas. Their major toxicities are the cytokine release syndrome (CRS) and the Immune-effector Cell Associated Neurotoxicity Syndrome (ICANS). These entities involve a hyperinflammatory cascade which is amplified through the mononuclear phagocytic system (MPS).
