Gandhi M, Bakhai V, Trivedi J, Mishra A, De Andrés F, LLerena A, Sharma R, Nair S. Current perspectives on interethnic variability in multiple myeloma: Single cell technology, population pharmacogenetics and molecular signal transduction. Transl Oncol 2022; 25:101532. [PMID: 36103755 PMCID: PMC9478452 DOI: 10.1016/j.tranon.2022.101532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 08/31/2022] [Accepted: 09/05/2022] [Indexed: 11/15/2022] Open
Abstract
This review discusses the emerging single cell technologies and applications in Multiple myeloma (MM), population pharmacogenetics of MM, resistance to chemotherapy, genetic determinants of drug-induced toxicity, molecular signal transduction. The role(s) of epigenetics and noncoding RNAs including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) that influence the risk and severity of MM are also discussed. It is understood that ethnic component acts as a driver of variable response to chemotherapy in different sub-populations globally. This review augments our understanding of genetic variability in ‘myelomagenesis’ and drug-induced toxicity, myeloma microenvironment at the molecular and cellular level, and developing precision medicine strategies to combat this malignancy. The emerging single cell technologies hold great promise for enhancing our understanding of MM tumor heterogeneity and clonal diversity.
Multiple myeloma (MM) is an aggressive cancer characterised by malignancy of the plasma cells and a rising global incidence. The gold standard for optimum response is aggressive chemotherapy followed by autologous stem cell transplantation (ASCT). However, majority of the patients are above 60 years and this presents the clinician with complications such as ineligibility for ASCT, frailty, drug-induced toxicity and differential/partial response to treatment. The latter is partly driven by heterogenous genotypes of the disease in different subpopulations. In this review, we discuss emerging single cell technologies and applications in MM, population pharmacogenetics of MM, resistance to chemotherapy, genetic determinants of drug-induced toxicity, molecular signal transduction, as well as the role(s) played by epigenetics and noncoding RNAs including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) that influence the risk and severity of the disease. Taken together, our discussions further our understanding of genetic variability in ‘myelomagenesis’ and drug-induced toxicity, augment our understanding of the myeloma microenvironment at the molecular and cellular level and provide a basis for developing precision medicine strategies to combat this malignancy.

Zhou X, Du J. CircRNAs: novel therapeutic targets in multiple myeloma. Mol Biol Rep 2022; 49:10667-10676. [PMID: 35729478 DOI: 10.1007/s11033-022-07668-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Accepted: 05/31/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Circular RNA (circRNA) is a type of non-coding RNA that has recently attracted the attention of researchers. Multiple myeloma (MM) is a hematological malignancy with a dismal prognosis that indicates a pressing need for better treatment alternatives, particularly in terms of biological indicators. According to recent research findings, the presence of circRNA is also closely related to the incidence and progression of malignant hemopathy. There have been, however, only a few investigations of circRNA in MM. MATERIAL AND METHODS This review will be on the biological properties and functions of circRNA in MM and a discussion of the clinical utility of circRNA in the diagnosis, prognosis, and treatment of MM. CONCLUSIONS CircRNA is involved in gene transcription, translation, and epigenetic modification as well as the regulation of cancer cell proliferation, invasion, and metastasis, and hence, promotes or inhibits the occurrence and progression of MM. Therefore, circRNA holds promise as a potential future MM biomarker.

Shen Q, Jiang Q, Cong Z, Zhou Y, Huang X, Zhu L, Xu X, Qian J. Knockdown of lncRNA AL928768.3 inhibits multiple myeloma cell proliferation by inducing cell cycle arrest in G0/G1 phase. ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:172. [PMID: 35280429 PMCID: PMC8908156 DOI: 10.21037/atm-21-6710] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 02/11/2022] [Indexed: 11/08/2022]
Abstract
Background Multiple myeloma (MM) is a B-lymphocyte-derived malignancy. It ranks as the second most common hematological malignancy, with relatively high morbidity and mortality. However, the molecular mechanisms of MM occurrence and development remain elusive. This study found that long non-coding RNA AL928768.3 (lncRNA AL) was abnormally expressed in MM samples. However, the effect and molecular mechanism of lncRNA AL on the occurrence and development of MM remains unclear. Methods Bone marrow fluids of MM patients (n=54) and volunteers (n=13) were collected and CD138+ cells were isolated. The expression level of lncRNA AL in MM cells was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the correlation between the expression level of lncRNA AL and the clinicopathological features of patients was analyzed. Lentiviral vectors targeting lncRNA AL knockdown were constructed and transfected into cells. After transfection, the effects of lncRNA AL knockdown on MM cell proliferation and the cell cycle were detected by the CCK-8 assay, clone formation assay, and flow cytometry. The effect of lncRNA AL knockdown on MM cell cycle-related proteins was detected by Western blot. In addition, tumorigenicity experiments were performed in nude mice to detect the effect of lncRNA AL knockdown on MM cell proliferation in vivo. Results LncRNA AL was highly expressed in MM patient samples and cell lines, and was significantly correlated with the disease stage of patients. Knockdown of lncRNA AL significantly inhibited the proliferation and colony formation of MM cells and induced cell cycle arrest in G0/G1 phase. Western blot analysis showed that knockdown of lncRNA AL significantly inhibited the expression of CDK2 and cyclin D1 and promoted the expression of cyclin suppressor p21. Knockdown of lncRNA AL significantly inhibited the proliferation of MM cells in nude mice. Conclusions LncRNA AL was highly expressed in MM patients. Knockdown of this gene significantly inhibited the proliferative ability of MM cells and induced cell cycle arrest in G0/G1 phase. Therefore, lncRNA AL may be a novel biological target molecule for the early diagnosis, treatment, and prognostic evaluation of MM patients.
