Efficiently restoring the tumoricidal immunity against resistant malignancies via an immune nanomodulator.

J Control Release 2020 May 27. Epub 2020 May 27.

Department of Pharmaceutics, Key Laboratory of Chemical Biology (Ministry of Education), School of Pharmaceutical Sciences, School of Pharmaceutical Sciences, Cheeloo College of Medicine, Shandong University, 44 Cultural West Road, Shandong Province 250012, PR China. Electronic address:

Bioinformatically triple negative breast cancer (TNBC) and colon adenocarcinoma (COAD), two typical "cold" cancers, were found overexpressed PD-L1 and CD47 respectively but neither of them showed satisfied response on its corresponding immune checkpoint blockade (ICB) in clinic. The initial immunotherapeutic resistance to ICB was essentially attributed to the so-called "cold" tumor immune milieu (TIM). To overcome tumor immunological tolerance against ICBs, here we report a versatile nano-modulator for point-to-point counteracting the immune-suppressors meanwhile boosting tumor T cell infiltration.

Identification of prognostic biomarkers and drug target prediction for colon cancer according to a competitive endogenous RNA network.

Mol Med Rep 2020 May 22. Epub 2020 May 22.

Department of Clinical Laboratory, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Chongming Branch, Shanghai 202150, P.R. China.

Colorectal cancer is one of the commoner digestive tract malignant tumor types, and its incidence and mortality rate are high. Accumulating evidence indicates that long‑chain non‑coding RNAs (lncRNAs) and protein‑coding RNAs interact with each other by competing with the same micro(mi)RNA response element (MREs) and serve an important role in the regulation of gene expression in a variety of tumor types. However, the regulatory mechanism and prognostic role of lncRNA‑mediated competing endogenous (ce)RNA networks in colon cancer have yet to be elucidated. Read More

Is It Time to Introduce PET/CT in Colon Cancer Guidelines?

Clin Nucl Med 2020 May 19. Epub 2020 May 19.

Nuclear Medicine Department, Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori, IRCCS, Meldola, Italy.

International colon cancer guidelines suggest F-FDG PET/CT in a few circumstances: (1) at disease presentation in case of suspected or proven metastatic synchronous adenocarcinoma; (2) in the workup of recurrent colon cancer with metachronous metastases documented by CT, MRI, or biopsy and in case of serial CEA elevation with negative colonoscopy and negative CT; and (3) in case of contraindication to iodine- and gadolinium-based contrast agents. However, review of the literature has shown that PET/CT can also be used in other scenarios with significant levels of diagnostic advantage. This review aims to emphasize differences between guidelines and scientific literature for the use of PET/CT in colon cancer. Read More

The halogenation of natural flavonoids, baicalein and chrysin, enhances their affinity to human protein kinase CK2.

IUBMB Life 2020 Jun 4;72(6):1250-1261. Epub 2020 May 4.

Institute of Biochemistry and Biophysics, Polish Academy of Sciences, Warsaw, Poland.

A series of halogenated derivatives of natural flavonoids: baicalein and chrysin were designed and investigated as possible ligands for the catalytic subunit of tumor-associated human kinase CK2. Thermal shift assay method, in silico modeling, and high-performance liquid chromatography-derived hydrophobicity together with IC values determined in biochemical assay were used to explain the ligand affinity to the catalytic subunit of human protein kinase CK2. Obtained results revealed that substitution of baicalein and chrysin with halogen atom increases their binding affinity to hCK2α, and for 8-chlorochrysin the observed effect is even stronger than for the reference CK2 inhibitor-4,5,6,7-tetrabromo-1H-benzotriazole.
