Major Research Findings

Bortezomib is a proteasome inhibitor that is used to treat multiple myeloma. 2 shows that XRK3F2, a selective ligand for the ZZ domain of p62, enhances the anti-tumor and bone-anabolic effects of bortezomib. XRK3F2 enhances the killing of human MM cells by promoting both bortezomib-mediated apoptosis and necroptosis, a process regulated by p62. It also preserves bone mass by promoting osteoblast differentiation and inhibiting osteoclast-mediated bone destruction. 9 shows that berberine protects against bortezomib-induced sciatic nerve and spinal cord damage in rats. Berberine exerts neuroprotective effects by alleviating oxidative stress and suppressing neuroinflammation. 4 shows that CUDC-101, a dual-target inhibitor of EGFR and HDAC, enhances the anti-myeloma effects of bortezomib. CUDC-101 inhibits the EGFR/PI3K signaling pathway and HDAC, leading to cell cycle G2/M arrest. 6 shows that low concentrations of bortezomib have specific cellular effects on the peripheral nervous system. Bortezomib causes dedifferentiation of Schwann cells, increased GFAP levels in satellite glial cells, and decreased expression levels of sensor and transducer ion channels in DRG neurons. 8 shows that flavonoids and non-flavonoid polyphenols enhance the anti-myeloma effects of bortezomib. These polyphenols enhance the efficacy of bortezomib by regulating cell signaling pathways associated with proliferation, apoptosis, and drug resistance. 7 shows that targeting arginase-1 exhibits antitumor effects in multiple myeloma and mitigates bortezomib-induced cardiotoxicity. Arginase inhibition effectively inhibits tumor progression and prevents the development of bortezomib-induced cardiotoxicity in mice. 11 shows that PC1, an antagonist of the prokineticin system, counteracts bortezomib-induced side effects. PC1 alleviates neuroinflammation and mood alterations in BTZ-treated mice. 5 shows that bortezomib exerts antitumor effects against malignant mesothelioma. Bortezomib induces mild endoplasmic reticulum stress in vitro and activates T cell response in vivo. 3 shows that the combination treatment of pinostilbene and bortezomib has cytotoxic and apoptotic effects on human multiple myeloma cells. Pinostilbene synergistically decreases MM cell viability and induces apoptosis when combined with bortezomib. 10 shows that the immunomodulatory effects of bortezomib are dose-dependent. Low-dose bortezomib ameliorates experimental autoimmune neuritis symptoms and improves nerve conduction. However, higher concentrations of bortezomib induce sensory neuropathy. 1 shows that bortezomib is not effective as a single agent in treating solid tumors. While bortezomib may be effective in combination with other agents, its effect is not always superior to the other agents alone.
