Summary: The study revealed that high MCCA expression in patients with MM led to improved overall survival. Knockdown of MCCA in MM cells resulted in increased survival rates after treatment with different anti-MM drugs. Mechanistic studies showed dysfunctional mitochondria in MCCA-KD cells and protein-protein interactions between MCCA and Bad. Additionally, MCCA was found to contribute to multidrug resistance in various human cancers.

Summary: This study reveals different mechanisms of resistance to bortezomib and ixazomib in multiple myeloma cell lines, with high expression levels of SGK1 and NF-kappa B p65 associated with low sensitivity to bortezomib and poor prognosis. Combining bortezomib and ixazomib with SGK1 or NF-kappa B inhibitors may enhance their efficacy in multiple myeloma treatment.

Summary: Multiple myeloma stem-like cells (MMSCs) contribute to drug resistance and relapse in multiple myeloma (MM). In this study, luteolin (LUT), a natural compound obtained from various plants, was found to effectively inhibit MM cell proliferation and overcome bortezomib (BTZ) resistance by decreasing the proportion of ALDH1(+) cells. RNA sequencing revealed that LUT inhibited transforming growth factor-beta signaling. LUT also reduced ALDH1(+) cell proportion in primary CD138+ plasma cells and synergistically enhanced the anti-myeloma effect of BTZ. These findings highlight LUT as a potential therapeutic agent for targeting MMSCs and overcoming drug resistance.

Summary: A major obstacle in cancer treatment is the development of drug resistance, particularly multidrug resistance (MDR), which refers to cross resistance to multiple drugs. One mechanism of MDR is the transfer of resistance proteins and nucleic acids through extracellular vesicles, specifically microparticles (MPs). This review focuses on the potential of MPs as novel clinical biomarkers for the early detection of MDR in multiple myeloma (MM).

Summary: Ipomoea asarifolia, a herbaceous plant from the Convolvulaceae family, has shown antiproliferative activity against multiple myeloma cells. A total of 15 compounds were isolated from the plant, with compound 3 demonstrating the most potent activity with an IC50 value of 3.0 μM against RPMI 8226 cells.

Summary: This study evaluated the chemosensitizing property of Andro in P-gp overexpressing multidrug-resistant (MDR) colchicine-selected KBCh(R) 8-5 cells. Molecular docking studies showed Andro exhibits higher binding interaction with P-gp than other studied transporters. Furthermore, Andro downregulates P-gp overexpression via NF-kappa B signaling in MDR cell lines and enhances the therapeutic effect of PTX in drug-resistant cells.

Summary: This study investigated the efficacy of THZ1, a covalent CDK7 inhibitor, in the treatment of multiple myeloma (MM). THZ1 showed anti-myeloma activity in MM models but had no effect on healthy CD34+ cells. It suppressed phosphorylation of RNA polymerase II carboxy-terminal domain and downregulated the transcription of BCL2 family of proteins, leading to G1/S arrest and apoptosis in MM cells.

Summary: EmrE is a multidrug efflux pump in Escherichia coli that transports drugs as a homodimer using energy from the proton motive force. Research suggests that the two Glu14 residues in the dimer have independent pKa values and are not electrostatically coupled, supporting a transport pathway with well-defined protonation states in each monomer of the dimer. The findings also propose a model, hop-free exchange, for how exchangers with conformation-dependent pKa values reduce proton leakage, relevant to the SMR family and transporters with inverted repeat domains.

Summary: In this study, the researchers evaluated the effects of an NF-kappa B inducing kinase (NIK) inhibitor, CW15337, on primary chronic lymphocytic leukemia (CLL) cells, CLL and multiple myeloma (MM) cell lines, and normal B- and T-lymphocytes. They found that CW15337 induced apoptosis and inhibited the non-canonical NF-kappa B signaling pathway, reversing BCL2 family-mediated resistance. The combination of CW15337 with fludarabine or ABT-199 showed synergistic cytotoxic effects.

Summary: Multiple Myeloma (MM) is a common and deadly hematological malignancy characterized by monoclonal proliferation within bone marrow. Curcumin, an active compound from turmeric, has shown promising effects in inhibiting cancer cell growth and preventing drug resistance in MM. Despite improvements in therapeutic strategies, MM remains incurable, but curcumin offers potential as a natural treatment option.

Summary: There is growing interest in the involvement of antioxidative systems, particularly Nrf2, in protecting against depression. Through a PubMed search, 89 eligible articles out of 208 results were identified. These studies suggest that Nrf2 is lower in depression and that antidepressant methods can increase its levels.
