Evaluation of Musculoskeletal Phenotype of the G608G Progeria Mouse Model With Lonafarnib, Pravastatin, and Zoledronic Acid as Treatment Groups
52 views | Jun 10 2020
Maria B Cubria et al. characterized the musculoskeletal phenotype of the homozygous G608G BAC-transgenic progeria mouse model, and determined the phenotype changes of HGPS mice after a five-arm preclinical trial of different treatment combinations with lonafarnib, pravastatin, and zoledronic acid.

Identifying off-target effects of etomoxir reveals that carnitine palmitoyltransferase I is essential for cancer cell proliferation independent of β-oxidation
110 views | Apr 12 2020
Yao CH et al. suggested that transport of at least some long-chain fatty acids into the mitochondria by CPT1 may be required for anabolic processes that support healthy mitochondrial function and cancer cell proliferation independent of FAO. [Read the Full Post]
Nicotinamide Phosphoribosyltransferase Inhibitor APO866 Prevents IL-1β-Induced Human Nucleus Pulposus Cell Degeneration via Autophagy
202 views | Jan 14 2020
Shi C et al. indicated that APO866 protects NP cells and induces autophagy by inhibiting IL-1β-induced NP cell degeneration and apoptosis, which may have therapeutic potential in IDD. [Read the Full Post]
Selective Cytotoxicity of the NAMPT Inhibitor FK866 Toward Gastric Cancer Cells With Markers of the Epithelial-Mesenchymal Transition, Due to Loss of NAPRT
89 views | Jan 14 2020
Lee J et al. showed that FK866 selectively kills gastric cancer cells with an EMT gene expression signature by inhibiting nicotinamide phosphoribosyltransferase in cells with NAPRT deficiency. Loss of NAPRT expression, frequently through promoter hypermethylation, is observed in many gastric tumors of the EMT subtype. FK866 might be used to treat patients with tumors of this subtype.

Pre-B cell colony enhancing factor induces Nampt-dependent translocation of the insulin receptor out of lipid microdomains in A549 lung epithelial cells
0 views | Jan 13 2020
Peng Q et al. concluded that PBEF can inhibit insulin signaling through the IR by Nampt-dependent promotion of IR translocation into the nonraft domains of A549 epithelial cells. PBEF-induced alterations in the spatial geometry of the IR provide a mechanistic explanation for insulin resistance in inflammatory states associated with upregulation of PBEF. [Read the Full Post]
Tipifarnib prevents development of hypoxia-induced pulmonary hypertension

Duluc L et al. demonstrated the importance of protein farnesylation in pulmonary vascular remodelling and provides a rationale for selective targeting of this pathway in pulmonary hypertension. [Read the Full Post]
Optimizing lonafarnib treatment for the management of chronic delta hepatitis: The LOWR HDV-1 study
156 views | Sep 05 2019
Yurdaydin C et al. showed the cytochrome P450 3A4 inhibitor, RTV, allows a lower LNF dose to be used while achieving higher levels of postabsorption LNF, yielding better antiviral responses and tolerability. In addition, combining LNF with PEG-IFNα achieved more substantial and rapid HDV-RNA reduction, compared to historical responses with PEG-IFNα alone. Twelve weeks of LNF can result in posttreatment HDV-RNA negativity in some patients, which we speculate results from restoring favorable immune responses. These results support further development of LNF with RTV boosting and exploration of the combination of LNF with PEG-IFN. [Read the Full Post]
Lonafarnib synergizes with azoles against Aspergillus spp. and Exophiala spp
165 views | Jun 13 2019
Qiao J et al. demonstrated that lonafarnib could enhance the in vitro antifungal activity of itraconazole, posaconazole and voriconazole against Aspergillus spp. and E. dermatitidis, suggesting that azoles, especially itraconazole and posaconazole, combined with farnesyltransferase inhibitor might provide a potential strategy to the management of Aspergillus and Exophiala infections. However, further studies are warranted to elucidate the underlying mechanism and to investigate the potential of reliable and safe application in clinical practice. [Read the Full Post]

Nicotinamide phosphoribosyltransferase inhibitor APO866 induces C6 glioblastoma cell death via autophagy
230 views | Apr 23 2019
Yang P et al indicated that APO866 induced pro-death autophagy in C6 glioblastoma cells by decreasing intracellular NAD, and low concentration of APO866 can be used as an autophagy inducer in autophagic-death sensitive glioblastoma. [Read the Full Post]
