Murine monoclonal antibodies to membrane antigens were generated by immunization with a crude cellular membrane preparation from suspension-cultured cells of Nicotiana glutinosa L. From a panel of thirteen monoclonal antibodies, seven were found to be directed against antigens present on the plasma-membrane by immunofluorescence visualization of antibody binding to the surface of isolated protoplasts. The corresponding set of plasma-membrane antigen(s) were present in root, shoot and leaf tissue and some but not all of these antigens were of wide species distribution, being found in Nicotiana tabacum L., N. plumbaginifolia L., Glycine max L., Phaseolus vulgaris L. and Triticum aestivum L. Topologically specific labeling of intact protoplasts with a monoclonal antibody reactive with an epitope present on the plasma-membrane specifically labeled a membrane fraction which equilibrated at a density of 1.14 kg/l following centrifugation in a sucrose gradient. In addition to use as biochemical markers for fractionation and molecular characterization of plasma-membranes, these monoclonal antibodies provide the basis for new selection tools in plant cell and gene manipulations.

Prognostic factors and outcomes of adjuvant and first-line metastatic treatments in melanoma a Turkish oncology group study.

Division of Medical Oncology, Marmara University School of Medicine, Istanbul, Turkey.
Management of melanoma has changed significantly with the discovery of targeted therapies and immune checkpoint inhibitors (ICI). Our aim in the study is to determine which treatment alternatives, specifically dabrafenib plus trametinib and ICIs, are effective in adjuvant therapy and which treatment is effective as first-line metastatic therapy. This retrospective, multicenter study included 120 patients diagnosed with stage IIIB-IIID melanoma receiving both adjuvant and first-line metastatic treatment between 2007 and 2023.

Glycosylation changes of circulating proteins carrying the CA19-9 antigen may offer new targets for detection methods to be explored for the diagnosis of epithelial ovarian cancer (EOC). Search for assay designs for targets initially captured by a CA19-9 antigen reactive antibody from human body fluids by probing with fluorescent nanoparticles coated with lectins or antibodies to known EOC associated proteins. CA19-9 antigens were immobilized from ascites fluids, ovarian cyst fluids or serum samples using monoclonal antibody C192 followed by probing of carrier proteins using anti-MUC16, anti-MUC1 and, anti STn antibodies and seven lectins, all separately coated on nanoparticles.

To investigate the efficacy and safety of transarterial chemoembolization (TACE) combined with sintilimab and bevacizumab biosimilar in the treatment of unresectable hepatocellular careinoma (uHCC). The clinical data of 64 patients with unresectable HCC, who were admitted to the First Affiliated Hospital of Soochow University between January 2021 and December 2023, were retrospectively analyzed. The patients were divided into a combination group (=43, receiving TACE combined with sintilimab and bevacizumab biosimilar) and control group (=21, receiving only sintilimab and bevacizumab biosimilar).

Background: Adalimumab is an effective treatment for juvenile idiopathic arthritis-associated uveitis. Data are scarce on the effects of discontinuing adalimumab after control of the disease had been reached. We aimed to assess efficacy and safety of discontinuing treatment in patients with juvenile idiopathic arthritis-associated uveitis.

Background: B7 homolog 3 (B7-H3), an overexpressed antigen across multiple solid cancers, represents a promising target for CAR T cell therapy. This study investigated the expression of B7-H3 across various solid tumors and developed novel monoclonal antibodies (mAbs) targeting B7-H3 for CAR T cell therapy.
Methods: Expression of B7-H3 across various solid tumors was evaluated using RNA-seq data from TCGA, TARGET, and GTEx datasets and by flow cytometry staining.
