    Abstract In leukemia, resistance to therapy is a major concern for survival. MAPK-interacting kinases (MNKs) have been identified as important activators of oncogenic-related signaling and may be mediators of resistance. Recent studies in leukemia models, especially acute myeloid leukemia (AML), have focused on targeting MNKs together with other inhibitors or treating chemotherapy-resistant cells with MNK inhibitors. The preclinical demonstrations of the efficacy of MNK inhibitors in these combination formats would suggest a promising potential for use in clinical trials. Optimizing MNK inhibitors and testing in leukemia models is actively being pursued and may have important implications for the future. These studies are furthering the understanding of the mechanisms of MNKs in cancer which could translate to clinical studies.

    Abstract For several decades there has been accumulating evidence implicating type I interferons (IFNs) as key elements of the immune response. Therapeutic approaches incorporating different recombinant type I IFN proteins have been successfully employed to treat a diverse group of diseases with significant and positive outcomes. The biological activities of type I IFNs are consequences of signaling events occurring in the cytoplasm and nucleus of cells. Biochemical events involving JAK/STAT proteins that control transcriptional activation of IFN-stimulated genes (ISGs) were the first to be identified and are referred to as "canonical" signaling. Subsequent identification of JAK/STAT-independent signaling pathways, critical for ISG transcription and/or mRNA translation, are denoted as "non-canonical" or "non-classical" pathways. In this review, we summarize these signaling cascades and discuss recent developments in the field, specifically as they relate to the biological and clinical implications of engagement of both canonical and non-canonical pathways.

    Abstract The objective was to compare the anti-proliferative effect of anthocyanin-rich plant extracts on human colon cancer cells and determine their mechanism of action. Eleven extracts were tested: red (RG) and purple grape, purple sweet potato, purple carrot, black and purple bean, black lentil (BL), black peanut, sorghum (SH), black rice, and blue wheat. HCT-116 and HT-29 inhibition correlated with total phenolics (r=0.87 and 0.77, respectively), delphinidin-3-O-glucoside concentration with HT-29 inhibition (r=0.69). The concentration inhibition fifty (IC50) for BL, SH, RG on HT-29 and HCT-116 cell proliferation ranged 0.9–2.0mg/mL. Extracts decreased expression of anti-apoptotic proteins (survivin, cIAP-2, XIAP), induced apoptosis, and arrested cells in G1. Anthocyanins exhibited tyrosine kinase inhibitory potential in silico and biochemically; cyanidin-3-O-glucoside had one of the highest binding affinities with all kinases, especially ABL1 (−8.5kcal/mol). Cyanidin-3-O-glucoside and delphinidin-3-O-glucoside inhibited EGFR (IC50=0.10 and 2.37µM, respectively). Cyanidin-3-O-glucoside was the most potent anthocyanin on kinase inhibition.

    Abstract The objective was to assess anti-progression and stimulatory immune response effects among anthocyanins (ANC) and their metabolites on human colorectal cancer cells in vitro and in silico. Pure phenolics including delphinidin-3-O-glucoside (D3G) and its metabolites, delphinidin (DC) and gallic acid (GA), were tested alone or in combination, on HCT-116 and HT-29 human colorectal cancer cells (100-600 µg/mL). HCT-116 and HT-29 50% inhibition concentrations (µg/mL) were 396 ± 23 and 329 ± 17 for D3G; 242 ± 16 and >600 for DC; and 154 ± 5 and 81 ± 5 for GA, respectively. Using molecular docking, cyanidin-3-O-glucoside (C3G) showed the highest potential to inhibit immune checkpoints: programmed cell death protein-1 (PD-1) (-6.8 kcal/mol) and programmed death-ligand-1 (PD-L1) (-9.6 kcal/mol). C3G, D3G, DC, GA, and D3G-rich extracts decreased PD-L1 protein expression in HCT-116 cells. C3G decreased PD-L1 fluorescence intensity by 39%. ANC decreased PD-1 expression in peripheral blood mononuclear cells in monoculture by 41% and 55%, and co-culture with HCT-116 and HT-29 cells by 39% and 26% (C3G) and 50% and 51% (D3G), respectively. D3G and C3G, abundant in plant foods, showed potential for binding with and inhibiting immune checkpoints, PD-1 and PD-L1, which can activate immune response in the tumor microenvironment and induce cancer cell death.

    Abstract The objective was to compare the impact of black lentil (BL) water and delphinidin 3-O-(2-O-β-d-glucopyranosyl-α-l-arabinopyranoside) (D3G)-rich lentil extracts on tumor development, inflammation and immune response in an azoxymethane (AOM)/dextran sodium sulfate (DSS) model. C57BL/6 mice were randomly separated into four groups: healthy control (n = 6), AOM/DSS control (n = 14), AOM/DSS + BL (600 mg/kg body wt, n = 12) and AOM/DSS + D3G (41 mg/kg body wt, equivalent to D3G concentration in BL, n = 12). Mice were given treatments for 11 weeks using a voluntary jelly administration. AOM/DSS + BL presented a lower (P < 0.05) disease activity index, throughout and at the end (2.4) compared with AOM/DSS (6.3). AOM/DSS + BL mice had an average of 7.8 neoplasms versus 12.8 for the AOM/DSS (P < 0.05). Proinflammatory cytokines were downregulated in the colon mucosa: interleukin (IL)-1β (-77.5%, -70.7%) and IL-6 (-44.4%, -44.9%) by AOM/DSS + BL and AOM/DSS + D3G, respectively, compared with AOM/DSS. IL-6 protein expression was decreased by BL in plasma (-72.6%) and gene expression in colon polyps (fold change: -4.0) compared with AOM/DSS. AOM/DSS + D3G non-polyp tissue gene expression clustered with the healthy control tissue with only four genes modified (secreted phosphoprotein 1 and CXC motif chemokine ligands 2, 5 and 10). AOM/DSS + BL downregulated programmed death-ligand 1 protein expression in colon tissue (-54.7%) and gene expression by 2.8-fold compared with the AOM/DSS control. In fecal samples, gallic and protocatechuic acids and epicatechin were found, and concentration of most amino acids was lower and unsaturated fatty acids were higher for AOM/DSS + BL and AOM/DSS + D3G. BL and D3G-rich extracts showed anti-inflammatory and proimmune response effects while BL additionally prevented growth of neoplasia.

    Abstract Anthocyanin-rich foods have shown potential health benefits. The objective was to evaluate the anti-proliferative effect of anthocyanin-rich purple and red corn on HCT-116 and HT-29 human colorectal cancer cells. IC50 values ranged from 1.1 to 6.3mg/mL, suggesting the corn extracts exhibited anti-proliferative effects on colon cancer cells; the red corn had the highest potential. All extracts increased apoptotic cells and impacted markers of apoptosis (BAX, Bcl-2, cytochrome c, TRAILR2/D5). Angiogenesis markers were also affected; a decreased expression of VEGF resulted with all corn extracts. Red corn significantly reduced other important markers of angiogenesis like Tie-2. Free binding energy of anthocyanins to tyrosine kinases was estimated at −7.86 and −7.76kcal/mol for cyanidin-3-glucoside with a non-receptor tyrosine kinase and peonidin with a receptor tyrosine kinase, respectively. The results indicate that anthocyanin-rich purple and red corn can potentially inhibit human colon cancer cell proliferation through promoting apoptosis and suppressing angiogenesis.
