Immune checkpoint-based therapy in myeloid malignancies: a promise yet to be fulfilled.

Immune checkpoint-based therapy in myeloid malignancies: a promise yet to be fulfilled. Expert Rev Anticancer Ther. 2019 Mar 19;:1-12 Authors: Bewersdorf JP, Stahl M, Zeidan AM Abstract INTRODUCTION: Immune system evasion is essential for tumor cell survival and is mediated by the immunosuppressive tumor microenvironment and the activation of inhibitory immune checkpoints. While immune checkpoint-based therapy yielded impressive results in several advanced solid malignancies such as melanoma and non-small cell lung cancer, its role in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) is still evolving. Areas covered: Here we review the immunology in the tumor microenvironment in the bone marrow and discuss the current preclinical and clinical data for immune checkpoint-based therapy in myeloid neoplasms. Expert commentary: Clinical trials of immune checkpoint inhibitors (ICI) in AML and MDS are still in early stages and reported results so far have been modest especially for monotherapy use in the refractory settings. However, there are preliminary data for synergistic effects for combination of multiple ICI with hypomethylating agents and conventional chemotherapy. ICI might also be effective in eradicating minimal residual disease and to prevent relapse following induction chemotherapy or hematopoietic stem cell transplant. Additional trials to provide insight into the efficacy and safety profile of immune checkpoint-based therapy, its opt...

This study examined how two aesthetic features of infographics affect people's evaluation of information presented in infographic: colour and visual complexity. The findings suggested colour and visual complexity were both strong predictors of information evaluation in infographic and they should be chosen carefully in the design of infographics.

In conclusion, it was identified that silencing of miR‑193a‑3p through hypermethylation can promote HER2 positive breast cancer progress by targeting GRB7, ERK1/2 and FOXM1 signaling. The function of miR‑193a‑3p in HER2 positive breast cancer implicates its potential application in therapy. PMID: 31017268 [PubMed - in process]

MicroRNA‑576‑3p inhibits the migration and proangiogenic abilities of hypoxia‑treated glioma cells through hypoxia‑inducible factor‑1α. Int J Mol Med. 2019 Jun;43(6):2387-2397 Authors: Hu Q, Liu F, Yan T, Wu M, Ye M, Shi G, Lv S, Zhu X Abstract The most common and aggressive type of brain cancer in adults is glioblastoma multiforme (GBM), and hypoxia is a common feature of glioblastoma. As the histological features of glioma include capillary endothelial cell proliferation, they are highly prone to invading the surrounding normal brain tissue, which is often one of the reasons for the ...

Detection of N6‑methyladenosine modification residues (Review). Int J Mol Med. 2019 Jun;43(6):2267-2278 Authors: Zhu W, Wang JZ, Xu Z, Cao M, Hu Q, Pan C, Guo M, Wei JF, Yang H Abstract Among a number of mRNA modifications, N6‑methyladenosine (m6A) modification is the most common type in eukaryotes and nuclear‑replicating viruses. m6A has a significant role in numerous cancer types, including leukemia, brain tumors, liver cancer, breast cancer and lung cancer. Although m6A methyltransferases are essential during RNA modifications, the biological functions of m6A and the underlying mechanisms rem...

In conclusion, IL‑18 served a dual function in colitis by regulating the function of goblet cells. The anti‑inflammatory effects of IL‑18 were observed in the early stage of colitis‑induced inflammation, while the pro‑inflammatory effects were observed in the later stages of the disease.

LPS‑induced upregulation of the TLR4 signaling pathway inhibits osteogenic differentiation of human periodontal ligament stem cells under inflammatory conditions. Int J Mol Med. 2019 Jun;43(6):2341-2351 Authors: Yu B, Li Q, Zhou M Abstract Toll‑like receptor 4 (TLR4) is a transmembrane receptor responsible for the activation of a number of signal transduction pathways. Despite its involvement in inflammatory processes, the regulation of TLR4 signaling in human periodontal ligament stem cells (hPDLSCs) under inflammatory conditions remains to be fully elucidated. The present study aimed to clarify ...
