[PMID: 38700979 PMCID: PMC11078693 DOI: 10.1016/j.xpro.2024.103060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 03/26/2024] [Accepted: 04/22/2024] [Indexed: 05/05/2024] Open
Abstract
Preservation of fine cellular details of semi-adherent or suspension cells for imaging by immunofluorescence is challenging. This protocol enables staining of floating cells with minimal morphological distortions, as we demonstrate with the semi-adherent multiple myeloma cell line RPMI 8226. We describe steps to better preserve structural details by fixing, permeabilizing, and staining cells in solution, while minimizing the number of centrifugation steps and centrifugation g-force. For complete details on the use and execution of this protocol, please refer to Osei-Amponsa et al.1.

Fuse H, Kikawada T, Cornette R. Effective methods for immobilization of non-adherent Pv11 cells while maintaining their desiccation tolerance. Cytotechnology 2023; 75:491-503. [PMID: 37841960 PMCID: PMC10575823 DOI: 10.1007/s10616-023-00592-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 08/24/2023] [Indexed: 10/17/2023] Open
Abstract
Pv11 was derived from embryos of the sleeping chironomid Polypedilum vanderplanki, which displays an extreme form of desiccation tolerance known as anhydrobiosis. Pre-treatment with a high concentration of trehalose allows Pv11 cells to enter anhydrobiosis. In the dry state, Pv11 cells preserve transgenic luciferase while retaining its activity. Thus, these cells could be utilized for dry-preserving antibodies, enzymes, signaling proteins or other valuable biological materials without denaturation. However, Pv11 cells grow in suspension, which limits their applicability; for instance, they cannot be integrated into microfluidic devices or used in devices such as sensor chips. Therefore, in this paper, we developed an effective immobilization system for Pv11 cells that, crucially, allows them to maintain their anhydrobiotic potential even when immobilized. Pv11 cells exhibited a very high adhesion rate with both biocompatible anchor for membrane (BAM) and Cell-Tak coatings, which have been reported to be effective on other cultured cells. We also found that Pv11 cells immobilized well to uncoated glass if handled in serum-free medium. Interestingly, Pv11 cells showed desiccation tolerance when trehalose treatment was done prior to immobilization of the cells. In contrast, trehalose treatment after immobilization of Pv11 cells resulted in a significant decrease in desiccation tolerance. Thus, it is important to induce anhydrobiosis before immobilization. In summary, we report the successful development of a protocol for the dry preservation of immobilized Pv11 cells.

Abstract
Epithelial-mesenchymal transition (EMT) is a key cellular transformation for many physiological and pathological processes ranging from cancer over wound healing to embryogenesis. Changes in cell migration, cell morphology and cellular contractility were identified as hallmarks of EMT. These cellular properties are known to be tightly regulated by the actin cytoskeleton. EMT-induced changes of actin-cytoskeletal regulation were demonstrated by previous reports of changes of actin cortex mechanics in conjunction with modifications of cortex-associated f-actin and myosin. However, at the current state, the changes of upstream actomyosin signaling that lead to corresponding mechanical and compositional changes of the cortex are not well understood. In this work, we show in breast epithelial cancer cells MCF-7 that EMT results in characteristic changes of the cortical association of Rho-GTPases Rac1, RhoA and RhoC and downstream actin regulators cofilin, mDia1 and Arp2/3. In the light of our findings, we propose that EMT-induced changes in cortical mechanics rely on two hitherto unappreciated signaling paths-i) an interaction between Rac1 and RhoC and ii) an inhibitory effect of Arp2/3 activity on cortical association of myosin II.

Newly Synthesized Melphalan Analogs Induce DNA Damage and Mitotic Catastrophe in Hematological Malignant Cancer Cells. Int J Mol Sci 2022; 23:ijms232214258. [PMID: 36430734 PMCID: PMC9693175 DOI: 10.3390/ijms232214258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/12/2022] [Accepted: 11/15/2022] [Indexed: 11/19/2022] Open
Abstract
Myeloablative therapy with highdoses of the cytostatic drug melphalan (MEL) in preparation for hematopoietic cell transplantation is the standard of care for multiple myeloma (MM) patients. Melphalan is a bifunctional alkylating agent that covalently binds to nucleophilic sites in the DNA and effective in the treatment, but unfortunately has limited therapeutic benefit. Therefore, new approaches are urgently needed for patients who are resistant to existing standard treatment with MEL. Regulating the pharmacological activity of drug molecules by modifying their structure is one method for improving their effectiveness. The purpose of this work was to analyze the physicochemical and biological properties of newly synthesized melphalan derivatives (EE-MEL, EM-MEL, EM-MOR-MEL, EM-I-MEL, EM-T-MEL) obtained through the esterification of the carboxyl group and the replacement of the the amino group with an amidine group. Compounds were selected based on our previous studies for their improved anticancer properties in comparison with the original drug. For this, we first evaluated the physicochemical properties using the circular dichroism technique, then analyzed the zeta potential and the hydrodynamic diameters of the particles. Then, the in vitro biological properties of the analogs were tested on multiple myeloma (RPMI8226), acute monocytic leukemia (THP1), and promyelocytic leukemia (HL60) cells as model systems for hematological malignant cells. DNA damage was assessed by immunostaining γH2AX, cell cycle distribution changes by propidium iodide (PI) staining, and cell death by the activation of caspase 2. We proved that the newly synthesized derivatives, in particular EM-MOR-MEL and EM-T-MEL, affected the B-DNA conformation, thus increasing the DNA damage. As a result of the DNA changes, the cell cycle was arrested in the S and G2/M phases. The cell death occurred by activating a mitotic catastrophe. Our investigations suggest that the analogs EM-MOR-MEL and EM-T-MEL have better anti-cancer activity in multiple myeloma cells than the currently used melphalan.

Abstract
Pyroptosis is a kind of cell necrosis mediated by inflammasomes. The caspase 1-induced cleavage of gasdermin D (GSDMD) is a canonical pathway to cause membrane pores and eventually cell pyroptosis. Poly-l-lysine (PLL) is widely used to enhance cell adhesion during experiments. Human THP-1 cells are a typical cell line used to study pyroptosis due to their monocytic and macrophage-like characteristics. However, it was found that THP-1 cells seeded on the PLL-coated slides died. To figure out the reason, we observed the morphology of THP-1 cells on PLL-coated slides, which showed obvious pore forming on the cell membranes and cell swelling. The indicated pyroptosis-related protein expression was evaluated and it showed that the conventional caspase-1 pathway of pyroptosis was activated through the NLRP3 inflammasome in THP-1 monocytes on the PLL-coated slides. Hence, PLL-guided cell adhesion induces cell pyroptosis in THP-1 monocytes, which calls for THP-1 dominant studies of pyroptosis to avoid the use of PLL-coated slides or PLL-related drugs.

Abstract
Bellevalia saviczii is a medicinal plant used as anti-rheumatic and anti-inflammatory herbal remedy in Iraqi-Kurdistan. The aim of this study was to evaluate the anti-inflammatory activity of its extract and the isolated homoisoflavonoid (Dracol) by studying the Ca2+-dependent NF-kB pathway. Nuclear translocation of p65 NF-kB subunit, as parameter of NF-kB activation, was visualized in human leukemic monocytes by immunofluorescence and Western blot analyses, after cell treatment with B. saviczii root extract or Dracol followed by Lipopolysaccharide stimulation. In parallel, Ca2+ signals responsible for NF-kB activation and levels of inflammatory cytokines were investigated. LPS-induced p65 translocation was evident in monocytes and both treatments, in particular that with Dracol, were able to counteract this activation. Intracellular Ca2+ oscillations were halted and the cytokine release reduced. These results confirm the traditional anti-inflammatory efficacy of B. saviczii and identify one of the molecules in the extract which appears to be responsible of this action.

Abstract
We developed a highly efficient method for patterning cells by a novel and simple technique called lift-off cell lithography (LCL). Our approach borrows the key concept of lift-off lithography from microfabrication and utilizes a fully biocompatible process to achieve high-throughput, high-efficiency cell patterning with nearly zero background defects across a large surface area. Using LCL, we reproducibly achieved >70% patterning efficiency for both adherent and non-adherent cells with <1% defects in undesired areas.

Abstract
Background: Selective serotonin reuptake inhibitor (SSRI) antidepressant drugs are the first-line of treatment for major depressive disorder (MDD) but are effective in <70% of patients. Our earlier genome-wide studies indicated that two genes encoding for cell adhesion proteins, close homolog of L1 (CHL1) and integrin beta-3 (ITGB3), and microRNAs, miR-151a-3p and miR-221/222, are implicated in the variable sensitivity and response of human lymphoblastoid cell lines (LCL) from unrelated individuals to SSRI drugs. Methods: The microRNAs miR-221, miR-222, and miR-151-a-3p, along with their target gene binding sites, were explored in silico using miRBase, TargetScan, microRNAviewer, and the UCSC Genome Browser. Luciferase reporter assays were conducted for demonstrating the direct functional regulation of ITGB3 and CHL1 expression by miR-221/222 and miR-151a-3p, respectively. A human LCL exhibiting low sensitivity to paroxetine was utilized for studying the phenotypic effect of CHL1 regulation by miR-151a-3p on SSRI response. Results: By showing direct regulation of CHL1 and ITGB3 by miR-151a-3p and miR-221/222, respectively, we link these microRNAs and genes with cellular SSRI sensitivity phenotypes. We report that miR-151a-3p increases cell sensitivity to paroxetine via down-regulating CHL1 expression. Conclusions: miR-151a-3p, miR-221/222 and their (here confirmed) respective target-genes, CHL1 and ITGB3, are implicated in SSRI responsiveness, and possibly in the clinical response to antidepressant drugs.

Abstract
We previously reported that the nucleoside antibiotic tunicamycin (TN), a protein glycosylation inhibitor triggering unfolded protein response (UPR), induced neutrophil extracellular trap-osis (NETosis)-like cellular suicide and, thus, discharged genomic DNA fibers to extracellular spaces in a range of human myeloid cell lines under serum-free conditions. In this study, we further evaluated the effect of TN on human promyelocytic leukemia HL-60 cells using time-lapse microscopy. Our assay revealed a previously unappreciated early event induced by TN-exposure, in which, at 30-60 min after TN addition, the cells extruded their nuclei into the extracellular space, followed by discharge of DNA fibers to form NET-like structures. Intriguingly, neither nuclear extrusion nor DNA discharge was observed when cells were exposed to inducers of UPR, such as brefeldin A, thapsigargin, or dithiothreitol. Our findings revealed novel nuclear dynamics during TN-induced NETosis-like cellular suicide in HL-60 cells and suggested that the toxicological effect of TN on nuclear extrusion and DNA discharge was not a simple UPR.

Abstract
Human myeloid HL-60 cells are usually cultured in suspension in medium containing 5% to 10% fetal bovine serum (FBS) and thus are often difficult to adhere to a coverslip. In this unit, we describe how removal of FBS from the culture medium facilitates adhesion of HL-60 cells to coverslips. Importantly, HL-60 cells that adhere to the coverslips immersed in FBS-free medium can be immobilized in situ by conventional chemical fixatives and thus permeabilized for probing cellular structures using specific dyes and/or reagents, followed by microscopic observation. All-trans-retinoic-acid-exposed differentiated HL-60 cells, which have properties similar to neutrophils, can also adhere efficiently to coverslips in FBS-free medium. Because the procedure is not complex and special equipment is not required, the simplicity and cost effectiveness of this FBS-free cell adhesion protocol may be beneficial to researchers who are interested in assessing the structure and function of suspension cells using microscopy.
