CI-1040 is an experimental drug that is being tested in patients who have advanced colorectal and lung cancer who failed no more than one prior chemotherapy regimen, breast cancer who have failed no more than 2 prior regimens and in patients with pancreatic cancer who have received no prior chemotherapy. CI-1040 is taken orally twice daily with meals. Patients are required to have blood tests periodically while receiving treatment and will be monitored closely throughout the trial for possible side effects and for response.

SNHG14 promotes triple‐negative breast cancer cell proliferation, invasion, and chemoresistance by regulating the ERK/MAPK signaling pathway

Article

Author: Xing, Ai‐Yan ; Liu, Long ; Xing, Chungen ; Li, Guang‐Xin ; Wang, Bin

AbstractThe functional role and molecular mechanisms of small‐nucleolar RNA host gene 14 (SNHG14) in triple‐negative breast cancer (TNBC) progression remain unclear. The expression levels of SNHG14 in breast cancer samples and cell lines were determined using real‐time quantitative polymerase chain reaction. Cell proliferation, migration, and invasion abilities were detected using MTS and transwell assays. By RNA sequencing, differentially expressed genes were identified between the SNHG14 siRNA and the negative control group. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were used to predict the targets and pathways regulated by SNHG14. pRAF, pMEK, and pERK expression were measured by western blot. The xenograft model was constructed to access the biological function of SNHG14 in vivo. A minimal patient‐derived xenograft model was established to evaluate the sensitivity to chemotherapy drugs. Our data indicated that SNHG14 expression was increased in TNBC tissues and cell lines. SNHG14 knockdown attenuated the proliferation, migration, and invasion abilities of TNBC cells both in vivo and in vitro. High SNHG14 expression was associated with lymph node metastasis and a high Ki67 index. The targets of SNHG14 were mainly enriched in the MAPK signaling pathway. pRAF, pMEK, and pERK expression were downregulated after being transfected with SNHG14 siRNA. Compared with the negative control group, the expression of CACNA1I, DUSP8, FGF17, FGFR4, FOS, PDGFRB, and DDIT3 was increased, and the expression of MKNK1 was decreased in the SNHG14 siRNA group. Minimal patient‐derived xenograft model demonstrated that knockdown of SNHG14 enhanced the sensitivity to Docetaxel in vivo. Compared with the DMSO group, the proliferation of Docetaxel‐resistant MDA‐MB‐231 cells was decreased in Dabrafenib, PD184352, and FR180204 treatment groups. SNHG14 knockdown inhibits TNBC progression by regulating the ERK/MAPK signaling pathway, which provides evidence for SNHG14 as a potential target for TNBC therapy.

Introduction:Cisplatin (DDP)-based chemotherapy remains the main therapeutic strategy for human gastric cancer (GC). Combination therapy with Chinese medicine monomers and DDP has been investigated as a means to enhance the anti-tumor effect of DDP while reducing toxicity.Material and Methods:Previous studies have shown that crocin combined with DDP can inhibit the apoptosis of BG-823 GC cells. However, the mechanism of this combination therapy in inhibiting GC is not fully unclear. In this study, we measured the IC50 values of crocin combined with DDP in AGS cells and assessed its effect on cell proliferation using an MTT assay. Furthermore, we assessed apoptosis, cell migration, and EMT-related protein levels by using flow cytometry, scratch assay, and Western blotting, respectively. Our results showed that crocin combined with DDP inhibited the proliferation, induced apoptosis, and inhibited invasion and EMT. Next, we performed RNA sequence and KEGG enrichment analysis on GC cells treated with Crocin+DDP.Results::The results showed that the most significant factor down-regulated by this combination therapy was Fibroblast growth factor receptor 3 (FGFR3) expression and that a differential gene was enriched in the MAPK/ERK pathway. We further constructed an FGFR3 OE transfection plasmid to overexpress FGFR3 and evaluate its effects on proliferation, apoptosis, migration, EMT, and MAPK/ERK pathway proteins in GC cells. We also conducted subcutaneous tumorigenesis experiments in nude mice to evaluate the effects of crocin and DDP on the progression of GC xenografts in vivo. Finally, we performed a rescue experiment using the MAPK/ERK pathway inhibitor PD184352.Conclusion:Our results showed that up-regulation of FGFR3 reversed the inhibitory effect of crocin+DDP on the MAPK/ERK signaling pathway. Still, this effect could be counteracted by PD184352, which simultaneously regulated the proliferation, apoptosis, and EMT of AGS cells. In conclusion, crocin, combined with DDP, inhibits proliferation, apoptosis, and EMT of GC through the FRFR3/MAPK/ERK pathway.

Spike-induced cytoarchitectonic changes in epileptic human cortex are reduced via MAP2K inhibition

Article

Author: Smith, Rachael A ; Loeb, Jeffrey A ; Maharathi, Biswajit ; Butler, Mitchell P ; Mir, Fozia

AbstractInterictal spikes are electroencephalographic discharges that occur at or near brain regions that produce epileptic seizures. While their role in generating seizures is not well understood, spikes have profound effects on cognition and behaviour, depending on where and when they occur. We previously demonstrated that spiking areas of human neocortex show sustained MAPK activation in superficial cortical Layers I–III and are associated with microlesions in deeper cortical areas characterized by reduced neuronal nuclear protein staining and increased microglial infiltration. Based on these findings, we chose to investigate additional neuronal populations within microlesions, specifically inhibitory interneurons. Additionally, we hypothesized that spiking would be sufficient to induce similar cytoarchitectonic changes within the rat cortex and that inhibition of MAPK signalling, using a MAP2K inhibitor, would not only inhibit spike formation but also reduce these cytoarchitectonic changes and improve behavioural outcomes. To test these hypotheses, we analysed tissue samples from 16 patients with intractable epilepsy who required cortical resections. We also utilized a tetanus toxin-induced animal model of interictal spiking, designed to produce spikes without seizures in male Sprague–Dawley rats. Rats were fitted with epidural electrodes, to permit EEG recording for the duration of the study, and automated algorithms were implemented to quantify spikes. After 6 months, animals were sacrificed to assess the effects of chronic spiking on cortical cytoarchitecture. Here, we show that microlesions may promote excitability due to a significant reduction of inhibitory neurons that could be responsible for promoting interictal spikes in superficial layers. Similarly, we found that the induction of epileptic spikes in the rat model produced analogous changes, including reduced neuronal nuclear protein, calbindin and parvalbumin-positive neurons and increased microglia, suggesting that spikes are sufficient for inducing these cytoarchitectonic changes in humans. Finally, we implicated MAPK signalling as a driving force producing these pathological changes. Using CI-1040 to inhibit MAP2K, both acutely and after spikes developed, resulting in fewer interictal spikes, reduced microglial activation and less inhibitory neuron loss. Treated animals had significantly fewer high-amplitude, short-duration spikes, which correlated with improved spatial memory performance on the Barnes maze. Together, our results provide evidence for a cytoarchitectonic pathogenesis underlying epileptic cortex, which can be ameliorated through both early and delayed MAP2K inhibition. These findings highlight the potential role for CI-1040 as a pharmacological treatment that could prevent the development of epileptic activity and reduce cognitive impairment in both patients with epilepsy and those with non-epileptic spike-associated neurobehavioural disorders.
