Underlying Disease Process

The purpose of this article is to present a general overview of the features of drug-induced movement disorders (DIMDs) comprised by Parkinsonism and extrapyramidal symptoms. Speech-language pathologists (SLPs) who work with patients presenting with these issues must have a broad understanding of the underlying disease process. This article will provide a brief introduction to the neuropathophysiology of DIMDs, a discussion of the associated symptomatology, the pharmacology implicated in causing DIMDs, and the medical management approaches currently in use.

This study aimed to investigate the mechanism of betulinic acid on multiple myeloma cell resistance to bortezomib. To this end, the bortezomib-resistant RPMI-8226-R cells were generated by prolonged treatment of RPMI-8226 cells with increasing concentrations of bortezomib. Based on the measurements of cell viability and colony number, RPMI-8226-R cells exhibited enhanced resistance to bortezomib than RPMI-8226 cells. Treatment with betulinic acid resulted in increased sensitivity of RPMI-8226-R to bortezomib. When RPMI-8226-R cells were co-treated with bortezomib and betulinic acid, there was an increase in apoptosis rate, cleaved caspase-3, cleaved caspase-9 expression and the decrease in p-AKT/AKT and p-mTOR/mTOR levels. These results suggest that betulinic acid enhances the sensitivity of RPMI-8226-R cells to bortezomib by inhibiting the activation of the AKT/mTOR pathway in bortezomib-resistant multiple myeloma cells.

Inflammatory Bowel

: Inflammatory bowel disease (IBD) is a general term for a group of chronic and progressive disorders. Several cellular and biomolecular pathways are implicated in the pathogenesis of IBD, yet the etiology is unclear. Activation of the mammalian target of rapamycin (mTOR) pathway in the intestinal epithelial cells was also shown to induce inflammation. This review focuses on the inhibition of the mTOR signaling pathway and its potential application in treating IBD. We also provide an overview on plant-derived compounds that are beneficial for the IBD management through modulation of the mTOR pathway. Data were extracted from clinical, in vitro and in vivo studies published in English between 1995 and May 2019, which were collected from PubMed, Google Scholar, Scopus and Cochrane library databases. Results of various studies implied that inhibition of the mTOR signaling pathway downregulates the inflammatory processes and cytokines involved in IBD. In this context, a number of natural products might reverse the pathological features of the disease. Furthermore, mTOR provides a novel drug target for IBD. Comprehensive clinical studies are required to confirm the efficacy of mTOR inhibitors in treating IBD.
