Genomic and transcriptomic analyses reveal a tandem amplification unit of 11 genes and mutations in mismatch repair genes in methotrexate-resistant HT-29 cells.

Exp Mol Med 2021 Sep 14. Epub 2021 Sep 14.

Asian Genome Institute, Seoul National University Bundang Hospital, Seongnamsi, 13605, Korea.

DHFR gene amplification is commonly present in methotrexate (MTX)-resistant colon cancer cells and acute lymphoblastic leukemia. In this study, we proposed an integrative framework to characterize the amplified region by using a combination of single-molecule real-time sequencing, next-generation optical mapping, and chromosome conformation capture (Hi-C). We identified an amplification unit spanning 11 genes, from the DHFR gene to the ATP6AP1L gene position, with high adjusted interaction frequencies on chromosome 5 (~2. Read More

The citrullinated/native index of autoantibodies against hnRNP-DL predicts an individual "window of treatment success" in RA patients.

Arthritis Res Ther 2021 Sep 14;23(1):239. Epub 2021 Sep 14.

Department of Rheumatology and Clinical Immunology, Charité - Universitätsmedizin Berlin, Charite Campus Mitte, Rheumatologisches Forschungslabor - AG Skriner, Chariteplatz 1 (intern Virchowweg 11, 5.OG, R011), 10117, Berlin, Germany.

Background: There is a need for biomarker to identify patients "at risk" for rheumatoid arthritis (risk-RA) and to better predict the therapeutic response and in this study we tested the hypothesis that novel native and citrullinated heterogeneous nuclear ribonucleoprotein (hnRNP)-DL autoantibodies could be possible biomarkers.

Methods: Using protein macroarray and ELISA, epitope recognition against hnRNP-DL was analysed in sera from different developed RA disease and diagnosed SLE patients. Toll-like receptor (TLR) 7/9 and myeloid differentiation primary response gene 88 (MyD88)-dependency were studied in sera from murine disease models. Read More

Differentially expressed miRNAs in bone after methotrexate treatment.

J Cell Physiol 2021 Sep 12. Epub 2021 Sep 12.

Clinical and Health Sciences, University of South Australia, Adelaide, South Australia, Australia.

Previous studies have shown that administration of antimetabolite methotrexate (MTX) caused a reduced trabecular bone volume and increased marrow adiposity (bone/fat switch), for which the underlying molecular mechanisms and recovery potential are unclear. Altered expression of microRNAs (miRNAs) has been shown to be associated with dysregulation of osteogenic and/or adipogenic differentiation by disrupting target gene expression. First, the current study confirmed the bone/fat switch following MTX treatment in precursor cell culture models in vitro. Read More

Complete ablation of tumors using synchronous chemoradiation with bimetallic theranostic nanoparticles.

Bioact Mater 2022 Jan 12;7:74-84. Epub 2021 Jun 12.

Zanjan Pharmaceutical Biotechnology Research Center, Zanjan University of Medical Sciences, Zanjan, Iran.

Synchronous chemotherapy and radiotherapy, termed chemoradiation therapy, is now an important standard regime for synergistic cancer treatment. For such treatment, nanoparticles can serve as improved carriers of chemotherapeutics into tumors and as better radiosensitizers for localized radiotherapy. Herein, we designed a Schottky-type theranostic heterostructure, BiS-Au, with deep level defects (DLDs) in BiS as a nano-radiosensitizer and CT imaging contrast agent which can generate reactive free radicals to initiate DNA damage within tumor cells under X-ray irradiation.
