Background & Aims: Inflammatory bowel diseases are multifactorial diseases commonly treated with either immunomodulatory drugs or anti-tumor necrosis factor (TNF). Currently, failure to respond to anti-TNF therapy (assessed no earlier than 8-12 weeks after starting treatment) occurs in 20%-40% of patients enrolled in clinical trials and in 10%-20% in clinical practice. Murine models of inflammatory bowel disease provide important tools to better understand disease mechanism(s).

Three-dimensional (3D) complex in vitro cell systems are well suited to providing meaningful and translatable results in drug screening, toxicity measurements, and biological studies. Reliable complex gastrointestinal in vitro models as a testbed for oral drug administration and toxicity are very valuable in achieving predictive results for clinical trials and reducing animal testing. However, producing these models is time-consuming due to the lengthy differentiation of HT29 or other cells into mucus-producing goblet cells or other intestinal cell lineages.

Colorectal cancer (CRC) carcinogenesis is generally the result of the sequential mutation and deletion of various genes; this is known as the normal mucosa-adenoma-carcinoma sequence. The aim of this study was to develop a predictor-classifier during the "adenoma-carcinoma" sequence using microarray gene expression profiles of primary CRC, adenoma, and normal colon epithelial tissues. Four gene expression profiles from the Gene Expression Omnibus database, containing 465 samples (105 normal, 155 adenoma, and 205 CRC), were preprocessed to identify differentially expressed genes (DEGs) between adenoma tissue and primary CRC.

Dendritic cells (DCs) represent a heterogeneous family of immune cells that link innate and adaptive immunity and their activation is linked to metabolic changes that are essential to support their activity and function. Hence, targeting the metabolism of DCs represents an opportunity to modify the inflammatory and immune response. Among the natural matrices, (Hop) compounds have recently been shown to exhibit immunomodulatory and anti-inflammatory activity.

Background: Despite the use of current standard therapy, the prognosis of patients with unresectable hepatocellular carcinoma (HCC) is poor, with median survival times of 40 mo for intermediate HCC (Barcelona Clinic Liver Cancer [BCLC] stage B) and 6-8 mo for advanced HCC (BCLC stage C). Although patients with early-stage HCC are usually suitable for therapies with curative intention, up to 70% of patients experience relapse within 5 years. In the past decade, the United States Food and Drug Administration has approved different immunogenic treatment options for advanced HCC, the most common type of liver cancer among adults.

The balance between anti-tumor and tumor-promoting immune cells, such as CD4+ Th1 and regulatory T cells (Tregs), respectively, is assumed to dictate the progression of hepatocellular carcinoma (HCC). The transforming growth factor beta (TGFβ) markedly shapes the HCC microenvironment, regulating the activation state of multiple leukocyte subsets and driving the differentiation of cancer associated fibroblasts (CAFs). The fibrotic (desmoplastic) reaction in HCC tissue strongly depends on CAFs activity.

Introduction: The aim of this multicenter comparison of balloon-occluded transarterial chemoembolization (B-TACE) versus conventional TACE (cTACE) in treating hepatocellular carcinoma (HCC) was to assess in which size range the 2 techniques offered higher complete response (CR) and objective response (OR) rates in a single session, and to evaluate the possibility of using B-TACE to reduce the need for re-treatment.

Methods: 325 patients were retrospectively evaluated: 91 patients in the B-TACE group (22 with cTACE [B-cTACE] and 69 with drug-eluting microsphere TACE [B-DEM-TACE]) and 234 in the cTACE group. The results were compared according to tumor size: (A) <30 mm, (B) 30-50 mm, and (C) >50 mm; OR and CR rates after the first session and the number of TACE re-interventions within a 6-month period were also evaluated using propensity score matching (PSM).

Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School, Boston, MA 02115, USA; Program in Cellular and Molecular Medicine, Boston Children's Hospital, Boston, MA 02115, USA. Electronic address:

NLRP6 is important in host defense by inducing functional outcomes including inflammasome activation and interferon production. Here, we show that NLRP6 undergoes liquid-liquid phase separation (LLPS) upon interaction with double-stranded RNA (dsRNA) in vitro and in cells, and an intrinsically disordered poly-lysine sequence (K350-354) of NLRP6 is important for multivalent interactions, phase separation, and inflammasome activation. Nlrp6-deficient or Nlrp6 mutant mice show reduced inflammasome activation upon mouse hepatitis virus or rotavirus infection, and in steady state stimulated by intestinal microbiota, implicating NLRP6 LLPS in anti-microbial immunity.

Article Synopsis
  • Frizzled (FZD) proteins act as key receptors in Wnt signaling, impacting MAPK pathways that can become dysfunctional in colorectal and gastric cancers.
  • Upregulated levels of the FZD10 protein in exosomes from the plasma of cancer patients correlate with poor prognosis and match expression levels in tumor tissues.
  • Silencing FZD10 reduces expression of cancer-related markers, suggesting that FZD10 in exosomes could serve as a valuable biomarker for diagnosing and predicting outcomes in colorectal and gastric cancers.
