CXCR6, a Newly Defined Biomarker of Tissue-Specific Stem Cell Asymmetric Self-Renewal, Identifies More Aggressive Human Melanoma Cancer Stem Cells [PDF]

open access: yesPLoS ONE 5(12): e15183, 2010, 2013
Background: A fundamental problem in cancer research is identifying the cell type that is capable of sustaining neoplastic growth and its origin from normal tissue cells. Recent investigations of a variety of tumor types have shown that phenotypically identifiable and isolable subfractions of cells possess the tumor-forming ability.

Growth hormone in the tumor microenvironment

open access: yesArchives of Endocrinology and Metabolism, 2020
Tumor development is a multistep process whereby local mechanisms enable somatic mutations during preneoplastic stages. Once a tumor develops, it becomes a complex organ composed of multiple cell types.

Role of YAP and TAZ in pancreatic ductal adenocarcinoma and in stellate cells associated with cancer and chronic pancreatitis. [PDF]

open access: yes, 2015
Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibrotic and inflammatory microenvironment that is formed primarily by activated, myofibroblast-like, stellate cells.

Transcribed ultraconserved noncoding RNAs (T-UCR) are involved in Barrett's esophagus carcinogenesis. [PDF]

open access: yes, 2014
Barretts esophagus (BE) involves a metaplastic replacement of native esophageal squamous epithelium (Sq) by columnar-intestinalized mucosa, and it is the main risk factor for Barrett-related adenocarcinoma (BAc).

Speeding through cell cycle roadblocks: Nuclear cyclin D1-dependent kinase and neoplastic transformation

open access: yesCell Division, 2008
Mitogenic induction of cyclin D1, the allosteric regulator of CDK4/6, is a key regulatory event contributing to G1 phase progression. Following the G1/S transition, cyclin D1 activation is antagonized by GSK3β-dependent threonine-286 (Thr-286 ...

Cellular interactions in the tumor microenvironment: the role of secretome [PDF]

open access: yes, 2019
Over the past years, it has become evident that cancer initiation and progression depends on several components of the tumor microenvironment, including inflammatory and immune cells, fibroblasts, endothelial cells, adipocytes, and extracellular matrix ...

Spectrum of Sinonasal Lesions with Expression of p16 and Ki-67 in Premalignant Lesions and Squamous Cell Carcinomas [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Sinonasal masses are heterogeneous group of non-neoplastic and neoplastic lesions originating from epithelial, mesenchymal, haematolymphoid and neuroendocrine cells.

Wnt/beta-catenin/Tcf signaling: A critical pathway in gastrointestinal tumorigenesis [PDF]

open access: yes, 2002
Cancers of the gastrointestinal tract, including the liver, bile ducts, and pancreas, constitute the largest group of malignant tumors. Colorectal cancer is one of the most common neoplastic diseases in Western countries and one of the leading causes of ...

Temporal dissection of K-ras(G12D) mutant in vitro and in vivo using a regulatable K-ras(G12D) mouse allele. [PDF]

open access: yesPLoS ONE, 2012
Animal models which allow the temporal regulation of gene activities are valuable for dissecting gene function in tumorigenesis. Here we have constructed a conditional inducible estrogen receptor-K-ras(G12D) (ER-K-ras(G12D)) knock-in mice allele that ...

LRIG1 as a potential novel marker for neoplastic transformation in ocular surface squamous neoplasia.

open access: yesPLoS ONE, 2014
The leucine rich repeats and immunoglobulin-like protein 1 (LRIG1) is a newly discovered negative regulator of epidermal growth factor receptor (EGFR) and a proposed tumor suppressor.
