Hypoxia-Induced Cleavage Of Soluble ephrinA1 From Cancer Cells Is Mediated By MMP-2 And Associates With Angiogenesis In Oral Squamous Cell Carcinoma

397 views | Dec 04 2019

Ma TT et al suggested a possible novel mechanism that ephrinA1 secretion is mediated by HIF-1α/MMP-2 signaling cascade which may play pivotal roles in OSCC neovascularization in a paracrine manner. [Read the Full Post]

Pre-metastatic niche triggers SDF-1/CXCR4 axis and promotes organ colonisation by hepatocellular circulating tumour cells via downregulation of Prrx1

552 views | Dec 04 2019

Tang Y et al. demonstrated that decreased expression of Prrx1 stimulates SDF-1/CXCR4 signalling and contributes to organ colonisation with blood CTCs in HCC. STAT3 inhibition and specific blockade of CXCR4 have clinical potential as therapeutics for eliminating organ metastasis in advanced HCC. [Read the Full Post]

3-Deazaneplanocin A and neplanocin A analogues and their effects on apoptotic cell death

449 views | Dec 01 2019

Tam EK et al. identified three compounds that show similar activities to DzNep. Two of these compounds show good pharmacokinetics and safety profiles. Attempts to correlate the observed synergistic apoptotic activities with measured S-adenosylhomocysteine hydrolase (SAHH) inhibitory activities suggest that the apoptotic activity of DzNep might not be directly due to its inhibition of SAHH.

DZNep is a global histone methylation inhibitor that reactivates developmental genes not silenced by DNA methylation

0 views | Dec 01 2019

Miranda TB et al. found that upon removal of DZNep, gene expression is reduced to its original state. This suggests that there is a homeostatic mechanism that returns the histone modifications to their "ground state" after DZNep treatment. Our data show the strong need for further development of histone methylation inhibitors. [Read the Full Post]

SB202190 inhibits endothelial cell apoptosis via induction of autophagy and heme oxygenase-1

470 views | Nov 29 2019

Schwartz M et al. opposed HO-1 to contribute to SB202190-mediated increases in metabolic activity and autophagy, respectively. [Read the Full Post]

Tri-methylation of H3K79 is decreased in TGF-β1-induced epithelial-to-mesenchymal transition in lung cancer

1425 views | Nov 29 2019

Evanno E et al. showed that histone methylation was modified during EMT, and combination of epigenetic compounds with conventional or targeted chemotherapy might contribute to reduce metastasis and to enhance clinical responses. [Read the Full Post]

Barasertib (AZD1152), a Small Molecule Aurora B Inhibitor, Inhibits the Growth of SCLC Cell Lines In Vitro and In Vivo

0 views | Nov 28 2019

Helfrich BA et al. suggested that SCLC tumors with cMYC amplification/high gene expression will frequently respond to Aurora B inhibitors and that clinical studies coupled with predictive biomarkers are indicated. [Read the Full Post]

Generation of pig induced pluripotent stem cells using an extended pluripotent stem cell culture system

586 views | Nov 27 2019

Xu J et al. demonstrated that stable iPS cells could be generated in LCDM medium, which could give rise to both embryonic and extraembryonic cells in vivo. However, the efficiency and level of chimeric contribution of pig LCDM-iPS cells were found low. [Read the Full Post]

First-in-Human Phase I Study of the Oral Inhibitor of Indoleamine 2,3-Dioxygenase-1 Epacadostat (INCB024360) in Patients with Advanced Solid Malignancies

645 views | Nov 25 2019

Beatty GL et al. showed that epacadostat was generally well tolerated, effectively normalized kynurenine levels, and produced maximal inhibition of IDO1 activity at doses of ≥100 mg BID. Studies investigating epacadostat in combination with other immunomodulatory drugs are ongoing. [Read the Full Post]

MCL-1 antagonism enhances the anti-invasive effects of dasatinib in pancreatic adenocarcinoma

Castillo L et al. suggested that MCL-1 antagonism, while reducing cell viability, may have an additional benefit in increasing the antimetastatic efficacy of dasatinib for the treatment of PDAC. [Read the Full Post]

Updates in the Clinical Development of Epacadostat and Other Indoleamine 2,3-Dioxygenase 1 Inhibitors (IDO1) for Human Cancers

638 views | Nov 24 2019

Komiya T et al. indicated that IDO1 is a promising target that can improve the treatment outcome in the field of Immuno-oncology. Several orally available IDO1 inhibitors including Epacadostat have entered human clinical trials over the last few years without a major safety concern. Although there is no objective response in single-agent trials, combination regimens with PD-1 inhibitors appear to exceed the activity of PD-1 inhibitors alone. Recent phase III ECHO 301 trial testing the combination of Epacadostat with Pembrolizumab in melanoma did not show superior outcome compared to Pembrolizumab alone. This lead to halting of other phase III trials using IDO1 inhibitors. In this minireview, we will discuss the recent clinical development of Epacadostat and other IDO1 inhibitors.
