Genomic stability at the coding regions of the multidrug transporter gene : insights into the development of alternative drug resistance mechanisms in human leukemia cells.

Cancer Drug Resist 2020 3;3:959-979. Epub 2020 Nov 3.

Division of Oncology, Department of Medicine, Stanford University School of Medicine, Stanford, CA 94305, USA.

Aim: Despite considerable efforts to reverse clinical multidrug resistance (MDR), targeting the predominant multidrug transporter ABCB1/P-glycoprotein (P-gp) using small molecule inhibitors has been unsuccessful, possibly due to the emergence of alternative drug resistance mechanisms. However, the non-specific P-gp inhibitor cyclosporine (CsA) showed significant clinical benefits in patients with acute myeloid leukemia (AML), which likely represents the only proof-of-principle clinical trial using several generations of MDR inhibitors. Nevertheless, the mutational mechanisms that may underlie unsuccessful MDR modulation by CsA are not elucidated because of the absence of CsA-relevant cellular models. Read More

Analysing "tear-drop" prints of acute promyelocytic leukemia (APML): immunophenotypic prognostication of APML by FCM.

Am J Blood Res 2021 15;11(4):446-457. Epub 2021 Aug 15.

ICMR-National Institute of Pathology, Safdarjung Hospital Campus Ansari Nagar, New Delhi, India.

Introduction: Acute promyelocytic leukemia (APML), although genetically and morphologically distinct from other AML (acute myeloid leukemia) subtypes, is one of the most best responsive acute myeloid leukemia. -Conventional diagnostic methods and morphological hints often fail in the majority of the cases in the peripheral laboratories owing to resource constraints, unavailability of cytogenetic work-up, hypogranular variants, morphological mimicry by AML-monocytic and myelo-monocytic, etc. Flowcytometry (FCM), however, can be utilized as a feasible and reliable immunophenotypic diagnostic and prognostic tool for prompt identification of APML.

TREM2: Keeping Pace With Immune Checkpoint Inhibitors in Cancer Immunotherapy.

Front Immunol 2021 3;12:716710. Epub 2021 Sep 3.

Cancer Institute, Xuzhou Medical University, Xuzhou, China.

To date, immune checkpoint inhibitors have been successively approved and widely used in clinical cancer treatments, however, the overall response rates are very low and almost all cancer patients eventually progressed to drug resistance, this is mainly due to the intricate tumor microenvironment and immune escape mechanisms of cancer cells. One of the main key mechanisms leading to the evasion of immune attack is the presence of the immunosuppressive microenvironment within tumors. Recently, several studies illustrated that triggering receptor expressed on myeloid cells-2 (TREM2), a transmembrane receptor of the immunoglobulin superfamily, was a crucial pathology-induced immune signaling hub, and it played a vital negative role in antitumor immunity, such as inhibiting the proliferation of T cells.
