Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...

BACKGROUND: Cyclooxygenase-2 (COX-2) overexpression in colorectal cancer increases levels of its pro-tumorigenic product prostaglandin E2 (PGE(2)). The recently identified colorectal tumour suppressor 15-prostaglandin dehydrogenase (15-PGDH) catalyses pros ...

Colorectal cancer (CRC) is among the three most commonly diagnosed cancers and one of the major causes of cancer-related morbidity and mortality. Despite the discovery of several predictive biomarkers, the 5-year survival rate for metastatic CRC is 15%. A ...

PURPOSE OF REVIEW: The last years of cancer research have established the concept of cancer stem cells (CSCs) as a subpopulation of cells within a tumor entirely responsible for tumorigenesis. This has aroused expectations that targeting cancer stem cells ...

Metastatic growth in distant organs is the major cause of cancer mortality. The development of metastasis is a multistage process with several rate-limiting steps. Although dissemination of tumour cells seems to be an early and frequent event, the successf ...

Despite the remarkable success of immune checkpoint blockade (ICB) therapy, most cancer patients still do not respond. We now find that immunotherapy can induce stem-like properties in tumors. Using mouse models of breast cancer, we observe that cancer ste ...

Hierarchical organization of tissues relies on stem cells, which either self-renew or produce committed progenitors predestined for lineage differentiation. Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify ...

We earlier showed that outside-in integrin signaling through POSTN-ITGAV interaction plays an important role in regulating adult he-matopoietic stem cell (HSC) quiescence. Here, we show that Itgav deletion results in increased frequency of phenotypic HSCs ...

Outside-in integrin signaling regulates cell fate decisions in a variety of cell types, including hematopoietic stem cells (HSCs). Our earlier published studies showed that interruption of periostin (POSTN) and integrin-av (ITGAV) interaction induces faste ...

Understanding the mechanisms that enable cancer cells to metastasize is essential in preventing cancer progression. Here we examine the metabolic adaptations of metastasis-initiating cells (MICs) in female breast cancer and how those shape their metastatic ...

Squamous cell carcinoma (SCC) of the lung is a frequent and aggressive cancer type. Gene amplifications, a known activating mechanism of oncogenes, target the 3q26-qter region as one of the most frequently gained/amplified genomic sites in SCC of various t ...

The most prevalent single-nucleotide substitution (SNS) found in cancers is a C-to-T substitution in the CpG motif. It has been proposed that many of these SNSs arise during organismal aging, prior to transformation of a normal cell into a precancerous/can ...

Upregulation of b-catenin, the primary mediator of the Wnt signaling pathway, plays an important role in the tumorigenesis of several types of human cancer. Targeting b-catenin to interfere with its ability to serve as a translational co-activator is consi ...

Polycomb repressive complexes (PRCs) are among the most important gatekeepers of establishing and maintaining cell identity in metazoans. PRC1, which plays a dominant role in this context, executes its functions via multiple subcomplexes, which all contrib ...

The genomes of many human CRCs have been sequenced, revealing a large number of genetic alterations. However, the molecular mechanisms underlying the accumulation of these alterations are still being debated. In this study, we examined colorectal tumours t ...

Contributions of null and hypomorphic alleles of Apc in mice produce both developmental and pathophysiological phenotypes. To ascribe the resulting genotype-to-phenotype relationship unambiguously to the Wnt/beta-catenin pathway, we challenged the allele c ...

Short alpha-helical peptides stabilized by linkages between constituent amino acids offer an attractive format for ligand development. In recent years, a range of excellent ligands based on stabilized alpha-helices were generated by rational design using a ...

Mutations and deregulation of adenomatous polyposis coli (APC) and beta-catenin are implicated in specific cancers of the pancreas, but the role of Wnt pathway in normal pancreas development and homeostasis is unknown [1-4]. This article reports a comprehe ...

Neurons and glia in the central nervous system originate from neural stem and progenitor cells that reside in the ventricular zones. Here we examine the role of beta-catenin in neural stem cell (NSC) regulation in mouse embryos lacking beta-catenin specifi ...

A long-standing question in biology is whether multipotent somatic stem and progenitor cells (SSPCs) feature molecular properties that could guide their system-independent identification. Population-based transcriptomic studies have so far not been able to ...
