RNAscope 2.5 HD Red assay

We have profiled, for the first time, an evolving human metastatic microenvironment, measuring gene expression, matrisome proteomics, cytokine and chemokine levels, cellularity, ECM organization and biomechanical properties, all on the same sample. Using biopsies of high-grade serous ovarian cancer (HGSOC) metastases that ranged from minimal to extensive disease, we show how non-malignant cell densities and cytokine networks evolve with disease progression.

Mouse papillomavirus type 1 (MmuPV1) provides, for the first time, the opportunity to study infection and pathogenesis of papillomaviruses in the context of laboratory mice. In this report, we define the transcriptome of MmuPV1 genome present in papillomas arising in experimentally infected mice using a combination of RNA-seq, PacBio Iso-seq, 5' RACE, 3' RACE, primer-walking RT-PCR, RNase protection, Northern blot and in situ hybridization analyses.

While all 2-methylene-19-nor analogs of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3) tested produce an increase in epidermal thickness in the rhino mouse, only a subset reduce utricle size (comedolysis). All-trans retinoic acid (atRA) also causes epidermal thickening and a reduction in utricle size in the rhino mouse.

Colorectal cancers comprise a complex mixture of malignant cells, non-transformed cells and microorganisms. Fusobacterium nucleatum is among the most prevalent bacterial species in colorectal cancer tissues.

One of the most encouraging developments in oncology has been the success of BRAF inhibitors in BRAF-mutant melanoma. However, in contrast to its striking efficacy in BRAF-mutant melanomas, BRAF inhibitor monotherapy is ineffective in BRAF-mutant colorectal cancer (CRC).

Abstract
Aim

NADPH oxidases are important sources of reactive oxygen species (ROS). Several Nox homologues are present together in the vascular system but whether they exhibit crosstalk at the activity level is unknown. To address this, vessel function of knockout mice for the cytosolic Nox organizer proteins p47phox, NoxO1 and a p47phox-NoxO1-double knockout were studied under normal condition and during streptozotocin-induced diabetes.

Abstract

The chicken yolk sac (YS) and small intestine are essential for nutrient absorption during the pre-hatch and post-hatch periods, respectively. Absorptive enterocytes and secretory cells line the intestinal villi and originate from stem cells located in the intestinal crypts. Similarly, in the YS, there are absorptive and secretory cells that presumably originate from a stem cell population.

Claudin-2 is a trans-membrane protein-component of tight junctions in epithelial cells. Elevated claudin-2 expression has been reported in colorectal cancer (CRC).

Immunohistochemistry remains the overwhelming technique of choice for test biomarker evaluation in both clinical or research settings when using formalin-fixed, paraffin embedded tissue sections. However, validations can be complex with significant issues about specificity, sensitivity and reproducibility.
