Regulation of gene expression by micrornas : targeting specificity, kinetics and function [PDF]

, 2011
Summary: Understanding gene regulation is a central question of molecular biology. For decades, gene expression was thought to be controlled by a complex network of proteins called transcription factors.

A Hybrid Bioprinting–Microfabrication Approach to Controllable Multitype Spheroid Arrays for Modeling Tumor Heterogeneity

Advanced Healthcare Materials, EarlyView.
This work introduces a “cancer‐in‐a‐well” technology that recreates tumor heterogeneity in vitro using multitype spheroid arrays. Combining bioprinting/microdispensing with microstructured culture devices, the system improves drug screening and modeling of tumor complexity.

Regulation of hepcidin and hemojuvelin expression and their role in iron homeostasis [PDF]

, 2010
Hepcidin is the key regulator of iron homeostasis acting as a negative regulator of intestinal iron absorption. Several proteins have recently been identified to act as upstream regulators of hepcidin expression, such as HFE and hemojuvelin (HJV ...

UDP‐Glucose‐6‐Dehydrogenase Mediated O‐GlcNAcylation of Tight Junction Protein 1 Suppresses Metastasis in Renal Cell Carcinoma

Advanced Science, EarlyView.
Our research unveiled a regulatory paradigm wherein TRIM25 orchestrates the ubiquitin‐mediated degradation of UGDH. UGDH modulates the protein stability of TJP1 by regulating O‐GlcNAcylation levels, effectively impeding the metastasis of ccRCC. Our insights elevate UGDH to a pivotal biomarker and tumor suppressor, marking the first demonstration that ...

Transcriptional regulation of the human c-myc gene [PDF]

, 1988
The involvement of c-myc in the genesis of animal neoplasia is now well documented for several systems. In order to define the precise role played by the myc gene in tumorigenesis, a better understanding of the normal regulation of myc expression is ...

Microglial Deubiquitinase OTUD7B Stabilizes STAT3 to Promote Neuroinflammation and Cognitive Decline in Alzheimer's Disease

Advanced Science, EarlyView.
. ABSTRACT Neuroinflammation driven by microglial activation is a defining feature of Alzheimer's disease (AD), yet the molecular mechanisms sustaining this proinflammatory state remain unclear. Here, we identify the deubiquitinase OTUD7B as a critical regulator of microglial activation and AD pathology.

Modelling neoplastic progression in epithelial ovarian cancer [PDF]

, 2010
A national screening programme could significantly reduce mortality from epithelial ovarian cancer (EOC). The biological events that occur in the early stages of development of EOCs remain poorly understood, thus hindering the discovery of biomarkers ...

Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

Advanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

Identification of genes differentially expressed as result of adenovirus type 5- and adenovirus type 12-transformation [PDF]

, 2009
Background: Cells transformed by human adenoviruses (Ad) exhibit differential capacities to induce tumours in immunocompetent rodents; for example, Ad12-transformed rodent cells are oncogenic whereas Ad5-transformed cells are not. The E1A gene determines
