Abstract
Oral cancer is one of the most common malignancies worldwide, accounting for 2% of all cases annually and 1.8% of all cancer deaths. To date, tissue biopsy and histopathological analyses are the gold standard methods for the diagnosis of oral cancers. However, oral cancer is generally diagnosed at advanced stages with a consequent poor 5-year survival (~50%) due to limited screening programs and inefficient physical examination strategies. To address these limitations, liquid biopsy is recently emerging as a novel minimally invasive tool for the early identification of tumors as well as for the evaluation of tumor heterogeneity and prognosis of patients. Several studies have demonstrated that liquid biopsy in oral cancer could be useful for the detection of circulating biomarkers including circulating tumor DNA (ctDNA), microRNAs (miRNAs), proteins, and exosomes, thus improving diagnostic strategies and paving the way to personalized medicine. However, the application of liquid biopsy in oral cancer is still limited and further studies are needed to better clarify its clinical impact. The present manuscript aims to provide an updated overview of the potential use of liquid biopsy as an additional tool for the management of oral lesions by describing the available methodologies and the most promising biomarkers.

Non-full-length Water-Soluble CXCR4 QTY and CCR5 QTY Chemokine Receptors: Implication for Overlooked Truncated but Functional Membrane Receptors. iScience 2020; 23:101670. [PMID: 33376963 PMCID: PMC7756140 DOI: 10.1016/j.isci.2020.101670] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 08/12/2020] [Accepted: 10/08/2020] [Indexed: 01/06/2023] Open
Abstract
It was posited that functionalities of GPCRs require full-length sequences that are negated by residue deletions. Here we report that significantly truncated nfCCR5QTY and nfCXCR4QTY still bind native ligands. Receptor-ligand interactions were discovered from yeast 2-hybrid screening and confirmed by mating selection. Two nfCCR5QTY (SZ218a, SZ190b) and two nfCXCR4QTY (SZ158a, SZ146a) were expressed in E. coli. Synthesized receptors exhibited α-helical structures and bound respective ligands with reduced affinities. SZ190b and SZ158a were reconverted into non-QTY forms and expressed in HEK293T cells. Reconverted receptors localized on cell membranes and functioned as negative regulators for ligand-induced signaling when co-expressed with full-length receptors. CCR5-SZ190b individually can perform signaling at a reduced level with higher ligand concentration. Our findings provide insight into essential structural components for CCR5 and CXCR4 functionality, while raising the possibility that non-full-length receptors may be resulted from alternative splicing and that pseudo-genes in genomes may be present and functional in living organisms. Y2H screening reveals ligand interaction from truncated CXCR4 and CCR5 in QTY form Truncated CCR5QTY and CXCR4QTY can be produced in E. coli and bind native ligands Reconverted receptors localize on membranes and regulate cell signaling in HEK293 Our finding indicates potential presence and function for truncated receptors

Abstract
Recent advancements in biochemical sciences have facilitated researchers to explore the structure and function of macro molecules in a cell. PAGE is one of the most favored and adapted laboratory techniques. Due to its simple and economical procedures, several variants or new modifications are routinely observed in the basic electrophoresis technique that comprises gel casting, electrophoresis, staining, and imaging process which consequently necessitates additional apparatuses/components in the laboratory. Operation of these additional apparatuses/components lengthens the pre- and postelectrophoresis procedures involving many intermittent tedious and time-consuming steps. A universal apparatus that can facilitate all such associated techniques is lacking and is of utmost importance for fast and effective results. An apparatus that can perform synchronized action of slab gel casting (16 × 16 cm), electrophoresis (SDS-PAGE), dye staining (Coomassie), and imaging (scanning) techniques with real-time monitoring through sensor technology is described in this article. The estimated cost (∼$150) of fabrication of the apparatus is very economical and simple assembly procedure of the main apparatus can be completed within ∼30 min after fabrication.
