Diffuse large b-cell lymphoma in the upper lip: case report

Diffuse large B-cell lymphomas (DLBCLs) are uncommon in the mouth; however, they are the commonest type of non-Hodgkin lymphomas at this site. Preferentially, they affect tonsils and their occurrence in the upper lip is rare. This work reports a case of DLBCL arising in the left upper lip of a 73-year-old white woman that was recently diagnosed as having advanced breast cancer besides being a carrier of Parkinson and Alzheimer diseases. The mucosal surface of the upper lip displayed a solitary, fast-growing, painful, ulcerated, reddish, and sessile 4-cm-sized swelling without cervical lymph node involvement at presentation.

In this study, platinum electrodes were fabricated on the bio-based poly(ethylene terephthalate) (Bio-PET) substrates for the development of flexible electrochemical sensors for the detection of Parkinson's disease biomarkers. Dopamine was detected by voltammetric measurements, displaying a 3.5 × 10−5 mol L−1 to 8.0 × 10−4 mol L−1 linear range with a limit of detection of 5.1 × 10−6 mol L−1. Parkinson's disease protein 7 (PARK7/DJ-1) was successfully detected by electrochemical impedance spectroscopy after elec...

Ion-exchange chromatography was applied for purification of the FCS from the crude extract of sulfated polysaccharides. Analysis of monosaccharide and sulfate content of HeSp revealed the molar ratio of GlcA:GalNAc:Fuc:SO3Na as 1.15:1:1.1:3.9. Molecular weight...

Cancer immune evasion is achieved through multiple layers of immune tolerance mechanisms including immune editing, recruitment of tolerogenic immune cells, and secretion of immunosuppressive cytokines. Recent success with immune checkpoint inhibitors in cancer immunotherapy suggests a dysfunctional immune synapse as a pivotal tolerogenic mechanism. Tumor cells express immune synapse proteins to suppress the immune system, which is often modulated by epigenetic mechanisms. When the methylation status of key immune synapse genes was interrogated, we observed disproportionately hypermethylated costimulatory genes and hypometh...

Increased rates of locoregional recurrence are observed in patients with basal-like breast cancer (BC) despite the use of radiation therapy (RT); therefore, approaches that result in radiosensitization of basal-like BC are critically needed. Using patients’ tumor gene expression data from 4 independent data sets, we correlated gene expression with recurrence to find genes significantly correlated with early recurrence after RT. The highest-ranked gene, TTK, was most highly expressed in basal-like BC across multiple data sets. Inhibition of TTK by both genetic and pharmacologic methods enhanced radiosensitivity in mul...

Antigen receptor–dependent (AgR-dependent) stimulation of the NF-κB transcription factor in lymphocytes is a required event during adaptive immune response, but dysregulated activation of this signaling pathway can lead to lymphoma. AgR stimulation promotes assembly of the CARMA1-BCL10-MALT1 complex, wherein MALT1 acts as (a) a scaffold to recruit components of the canonical NF-κB machinery, and (b) a protease to cleave and inactivate specific substrates, including negative regulators of NF-κB. In multiple lymphoma subtypes, malignant B cells hijack AgR signaling pathways to promote their own growth...

Tumor cells are in an adhesion profile during cell-cell and cell-matrix interaction. However, it is challenging for current platforms (e.g., typical droplet systems) to measure MMP9 secreted by single cells in an adhesion profile and retrieve the cells of interest for downstream analysis. Herein, we report a single-cell protease sensor (SCPS) based on ‘...

In this study, protein-based nanoparticles were constructed with TRAIL and a dipeptide, diphenylalanine (FF), through molecular self-assembly. TRAIL-FF nanoparticles with sizes ranging from 60 nm to 500 nm could be prepared by controlling the concentration and the ratio of the two components. These nanoparticles could locate around the cytomembrane of MCF-7 cells due to the specific interaction between TRAIL and death receptors, thus transduce apoptotic signal. Therefore, the TRAIL-FF nanoparticles showed distinct killing effect on the cancer cells, such as MCF-7 and H460 cells, and the IC50 of the nanopartic...
