CLL Cells within the Proliferation Centers of the Patient Lymph Nodes Are Enriched for Notch Signaling, Thus NOTCH a Viable Target for CLL Therapy
(ASH 2023)
- "Therefore, as a next logical step we treated the MEC-1 and OSU-CLL cells in culture and primary CLL cell from patients with NOTCH inhibitor RO4929097 (RO), a γ-secretase inhibitor for 24, 48 and 72 hours in vitro...This work was partially supported by bridge funding from the American Association of Hematology awarded to Dr. Runqing Lu, who passed away during the pursuit of this study."

Steric Hindrance By APRIL in Binding of BCMA-Directed Bispecific Antibodies: A Novel Refractory Mechanism of BCMA-Directed Immunotherapies in Multiple Myeloma
(ASH 2024)
- "mBCMA is shed off as soluble BCMA (sBCMA) by γ-secretase; treatment with the γ-secretase inhibitor RO4929097 substantially increased mBCMA levels on MM cells while reducing sBCMA...We further investigated the effects of APRIL on binding of the anti-BCMA/anti-CD3 bispecific Abs, teclistamab and elranatamab to BCMA in MM cells...Therefore, APRIL derived from OCs might cause steric hindrance of BCMA from anti-BCMA Ab binding and alleviate the efficacy of immunotherapies targeting BCMA. Further study is warranted to overcome the resistant mechanisms for BCMA-directed immunotherapies."

Screening of common genomic biomarkers to explore common drugs for the treatment of pancreatic and kidney cancers with type-2 diabetes through bioinformatics analysis.
(PubMed, Sci Rep)
- "Finally, we identified six top-ranked drug molecules (NVP.BHG712, Irinotecan, Olaparib, Imatinib, RG-4733, and Linsitinib) as potential common treatments for PC, KC and T2D during their co-existence, supported by the literature reviews. Thus, this bioinformatics study provides valuable insights and resources for developing a genome-guided common treatment strategy for PC and/or KC patients who are also suffering from T2D."

Structural basis of human γ-secretase inhibition by anticancer clinical compounds.
(PubMed, Nat Struct Mol Biol)
- "Here we report the cryo-electron microscopy structures of human γ-secretase bound individually to five clinically tested GSIs (RO4929097, crenigacestat, BMS906024, nirogacestat and MK-0752) at overall resolutions of 2.4-3.0 Å. The size and shape of the binding pocket are induced by the bound GSI. Analysis of these structural features suggest strategies for modification of the GSI with improved inhibition potency."

RO4929097 inhibits NICD3 to alleviate pulmonary hypertension via blocking Notch3/HIF-2α/FoxM1 signaling pathway.
(PubMed, In Vitro Cell Dev Biol Anim)
- "RO4929097 and plasmids including overexpression-NICD3 (oe-NICD3) and NICD3 small interfering RNA (siRNA) were used to alter the expression of NICD3, and HIF-2α inhibitor PT-2385 was used to alter the expression of HIF-2α. Our data suggest that RO4929097 regulates the Notch3/HIF-2α/FoxM1 signaling pathway by inhibiting the expression of NICD3, thereby inhibiting hypoxia-induced proliferation of HPASMCs. In vivo experiments also confirmed that RO4929097 could alleviate PH as a potential therapeutic strategy."

Screening of differential gene expression patterns through survival analysis for diagnosis, prognosis and therapies of clear cell renal cell carcinoma.
(PubMed, PLoS One)
- "Then we detected 10 repurposable drug molecules (Irinotecan, Imatinib, Telaglenastat, Olaparib, RG-4733, Sorafenib, Sitravatinib, Cabozantinib, Abemaciclib, and Dovitinib.) by molecular docking with KGs-mediated receptor proteins. Their ADME/T analysis and cross-validation with the independent receptors, also supported their potent against ccRCC. Therefore, these outputs might be useful inputs/resources to the wet-lab researchers and clinicians for considering an effective treatment strategy against ccRCC."

PS1 regulates processing and angiogenic signalling of VEGFR2; effects of FAD mutants.
(AAIC 2024)
- "This loss of function is comparable to the effect of γ-secretase inhibitor RO4929097... PS1 FAD mutants decrease production of signaling peptide VEGFR2/CTF2 probably due to reduced γ-secretase activity of FAD mutants. Interestingly FAD mutations do not seem to affect the PS1-VEGFR2 association. Our data support that PS1 regulates downstream signaling and angiogenic functions of VEGFR2."

Cdk4 Regulates Glioblastoma Cell Invasion and Stemness and Is Target of a Notch Inhibitor Plus Resveratrol Combined Treatment.
(PubMed, Int J Mol Sci)
- "In this study, we found that in GBM cells, treatment with low toxicity doses of the γ-secretase inhibitor RO4929097 (GSI), blocking the Notch pathway activity, in combination with resveratrol (RSV) was able to reverse the basal mesenchymal phenotype to an epithelial-like phenotype, affecting invasion and stemness interplay...The exogenous expression of a constitutively active Cdk4 mutant prevented the RSV + GSI inhibitory effects in GBM cell motility/invasion and augmented the expression of stemness-specific markers, as well as the neurosphere sizes/forming abilities in untreated cells. In conclusion, we propose that Cdk4 is an important regulator of GBM stem-like phenotypes and invasive capacity, highlighting how the combined treatment of Notch inhibitors and RSV could be prospectively implemented in the novel therapeutic strategies to target Cdk4 for these aggressive brain tumors."

Anti-tumor activity of HPN217, a BCMA-targeting tri-specific T cell engager, is enhanced by γ-secretase inhibitors in preclinical models
(AACR 2023)
- P1 | "To evaluate the effects of GSIs on BCMA expression, MM cell lines MOLP8, KMS-12-BM, and MM.1S were incubated with GSIs LY3039478, PF03084014, or RO4929097overnight. By contrast, the combination of HPN217 and LY3039478 led to a significant increase in survival compared to vehicle or either monotherapy, with a median survival of 43 days. Taken together these results demonstrate the potential utility of GSIs to enhance the anti-tumor activity of HPN217 and supports further investigation of this combinatorial approach in patients."

Targeting notch signaling pathway in breast cancer stem cells through drug repurposing approach.

- "In-silico docking potential of Venetoclax was better than the standard γ-secretase inhibitor RO4929097. Venetoclax appeared as the most promising drug of the 1615 FDA-approved drugs. Our in-silico findings suggest that Venetoclax may act as a γ-secretase inhibitor against the Notch signaling pathway in breast cancer stem cells."

Taken together, these results demonstrate that down-regulated NEDD4L facilitates LUAD progression by activating Notch signaling, and NEDD4L may be a promising target to treat LUAD."

PS1 FAD mutant M146V decreases VEGF-induced angiogenesis in brain endothelial cells.

Our data also show that PS1 FAD mutant decreases angiogenic functions of pCEC. Importantly the effects of PS1 FAD mutants occur in the absence of amyloid plaques and neurofibrillary tangles indicating that PS1 FAD mutants can affect angiogenesis independent of the neuropathological hallmarks of AD."

Although accrual to this study was not completed, vismodegib did not meaningfully enhance the clinical efficacy of RO4929097 in an unplanned analysis. GSIs and GSIs plus vismodegib can inhibit intratumoral Notch and downstream pAkt signaling."

DR-5 and DLL-4 mAb Functionalized SLNs of Gamma-Secretase Inhibitors- An Approach for TNBC Treatment.

The delivery system is designed to deliver the drug cargo precisely to TNBCs through its DR-5 receptors and hence expected to reduce the off-target side effects of GSIs. Further, DLL4 mAb and GSIs are expected to act synergistically to block the Notch signal mediated BCSCs proliferation, differentiation, and metastasis."
