Identification of an effective chemotherapy and DNA damage response inhibitor combination for diffuse large b cell lymphoma

Chemotherapy forms the backbone of treatment for Diffuse Large B Cell Lymphoma (DLBCL); however, <∼20% of tumors are chemoresistant. Inhibitors of the DNA damage response (DDR) show promise as chemosensitizers. We therefore set up an in-vitro screen to identify an optimal chemotherapy-DDR inhibitor (DDRi) combination in a panel of DLBCL cell lines.

Overexpression of interleukin-23, but not interleukin-17, as an immunologic signature of subclinical intestinal inflammation in ankylosing spondylitis

Objective Subclinical gut inflammation is common in spondylarthritis, but the immunologic abnormalities underlying this process are undefined. Perturbation of the interleukin-23 (IL-23)/Th17 axis has emerged as a fundamental trigger of chronic inflammation. This study was undertaken to investigate the expression and tissue distribution of IL-23/Th17–related molecules in Crohn's disease (CD) and in subclinical gut inflammation in ankylosing spondylitis (AS). Methods Quantitative gene expression analysis of Th1/Th2 and IL-23/Th17 responses was performed in intestinal biopsy samples obtained from 12 patients with CD, 15 patients with AS, and 13 controls. IL-23 tissue distribution and identific…

Biocompatibility and biodegradability of electrospun phea-pla scaffolds: Our preliminary experience in a murine animal model

We obtained a nano-fibrillar scaffold starting from a polymeric solution which, through electrospinning, gave a biodegradable material with optimal mechanical features and the capacity to allow cell adhesion. In this paper we report the in-vivo application on a murine animal model of two electrospun biodegradable materials, specifically designed to create tubular structures. In one case PHEA-PLA was co-spun with silk fibroin (Fibro-PHEAPLA) by a parallel electrospinning process to obtain a scaffold with two different polymeric fibers. In the other case, PHEA-PLA was mixed with polycaprolactone (PCLPHEA-PLA) to obtain a hybrid fibers scaffold. The in-vitro assay showed fibroblast colonizatio…

A variant of the LRP4 gene affects the risk of chronic lymphocytic leukaemia transformation to Richter syndrome

Richter syndrome (RS) represents the transformation of chronic lymphocytic leukaemia (CLL) to aggressive lymphoma. Risk factors of CLL transformation to RS are only partly known. We explored the role of the host genetic background as a risk factor for RS occurrence. Forty-five single nucleotide polimorphisms (SNPs) known to be relevant for CLL prognosis were genotyped in a consecutive cohort of 331 CLL, of which 21 had transformed to RS. After correcting for multiple testing and adjusting for previously reported RS risk factors, the LRP4 rs2306029 TT variant genotype was the sole SNP independently associated with a higher risk of RS transformation (Hazard Ratio: 4·17; P = 0·001; q = 0·047).…

Molecular profiling of blastic plasmacytoid dendritic cell neoplasm reveals a unique pattern and suggests selective sensitivity to NF-kB pathway inhibition.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease of controversial origin recently recognized as a neoplasm deriving from plasmacytoid dendritic cells (pDCs). Nevertheless, it remains an orphan tumor with obscure biology and dismal prognosis. To better understand the pathobiology of BPDCN and discover new targets for effective therapies, the gene expression profile (GEP) of 25 BPDCN samples was analyzed and compared with that of pDCs, their postulated normal counterpart. Validation was performed by immunohistochemistry (IHC), whereas functional experiments were carried out ex vivo. For the first time at the molecular level, we definitely recognized the cellular derivati…
