Oncogenic transformed cells represent an in vitro system mimicking early-stage carcinogenesis. These precancerous cells are subject to a selective removal via apoptosis induced by neighbor cells. By modulating the underpinning intercellular signaling mediated by cytokines and reactive oxygen/nitrogen species, ionizing radiation enhances this removal of precancerous cells in vitro, at doses from a few mGy to a few Gy.

Tumor progression is regulated by a complex interplay between neoplastic cells and the tumor microenvironment. Tumor-associated macrophages have been shown to promote breast cancer progression in advanced disease and more recently, in early stage cancers. However, little is known about the macrophage-derived factors that promote tumor progression in early stage lesions. Read More

CD34 is a transmembrane glycoprotein that is thought to be involved in the modulation of cell adhesion and signal transduction. The connective tissue stroma of virtually all human organs contain large amounts of resident CD34+ fibrocytes, which are involved in multiple functions such as wound healing, secretion of cytokines and also participate in stromal remodeling. It has been seen in various studies that absence of CD34+ fibrocytes within the stroma is associated with invasive carcinomas. Read More

Expression of the cytokine IL-11 is elevated in human Helicobacter pylori infection and progressively increases with worsening gastric pathology. Additionally, IL-11 is required for tumour development in STAT3 dependent murine models of gastric cancer (GC) and, when administered acutely, causes resolving atrophic gastritis. However, it is unclear whether locally elevated IL-11 ligand expression can, in isolation from oncogenic gp130-JAK-STAT pathway mutations, initiate GC pathogenesis. Read More

Background: Metabolic syndrome contributing to nonalcoholic fatty liver disease (NAFLD) can lead to hepatic dysfunction, steatohepatitis, cirrhosis, and hepatocellular carcinoma.
Aims: In this study, we tested whether diet-induced fatty liver in a mouse model physiologically mimicked human NAFLD, and whether transcriptional alterations in mouse fatty liver signified risk for the development of hepatitis, cirrhosis, and/or hepatocellular carcinoma.
Methods: SAMP6 strain mice were fed a low-fat diet or high-fat diet (HFD) for 6 months. Read More

Most ovarian carcinomas are high-grade serous carcinomas (HGSC) that contain TP53 mutations, present at advanced stage, and eventually become resistant to chemotherapy. The rapid evolution of this disease has been attributed to an origin in the distal fallopian tube, in the form of serous tubal intraepithelial carcinomas (STICs). This has led to a disease model where malignancy develops first in the tube and spreads to the peritoneum or regional lymph nodes. Read More

An epigenetic modulator Additional sex combs-like 1 (ASXL1) is recurrently mutated in myeloid neoplasms such as myelodysplastic syndromes (MDS), acute myeloid leukemia (AML) and myeloproliferative neoplasms (MPNs). ASXL1 mutations are also frequently detected in clonal hematopoiesis with indeterminate potential (CHIP), which is the clonal expansion of premalignant hematopoietic cells without any evidence of hematological malignancies. Thus, understanding the roles of ASXL1 in hematopoiesis and myeloid neoplasms is a clinically crucial issue. Read More

Introduction: Endometrial hyperplasia may be either a benign proliferation or a premalignant lesion. In order to differentiate these two conditions, two possible histologic classifications can be used: the World Health Organization (WHO) classification and the Endometrial Intraepithelial Neoplasia (EIN) classification. The 2018 European Society of Gynaecological Oncology guidelines recommend the use of immunohistochemistry for tumor suppressor protein phosphatase and tensin homolog (PTEN) to improve the differential diagnosis.

Myelodysplastic syndromes (MDS) frequently progress to acute myeloid leukemia (AML); however, the cells leading to malignant transformation have not been directly elucidated. As progression of MDS to AML in humans provides a biological system to determine the cellular origins and mechanisms of neoplastic transformation, we studied highly fractionated stem cell populations in longitudinal samples of patients with MDS who progressed to AML. Targeted deep sequencing combined with single-cell sequencing of sorted cell populations revealed that stem cells at the MDS stage, including immunophenotypically and functionally defined pre-MDS stem cells (pre-MDS-SC), had a significantly higher subclonal complexity compared to blast cells and contained a large number of aging-related variants.

CagA is a secreted effector protein that contributes to gastric carcinogenesis. Previous studies showed that there is variation among strains in steady-state levels of CagA, and that a strain-specific motif downstream of the transcriptional start site (+59 motif) was associated with both high levels of CagA and premalignant gastric histology. The 5' untranslated region contains a predicted stem-loop-forming structure adjacent to the +59 motif. Read More

Cellular senescence is a typical tumor-suppressive mechanism that restricts the proliferation of premalignant cells. However, mounting evidence suggests that senescent cells, which also persist in vivo, can promote the incidence of aging-related disorders principally via the senescence-associated secretory phenotype (SASP), among which cancer is particularly devastating. Despite the beneficial effects of the SASP on certain physiological events such as wound healing and tissue repair, more studies have demonstrated that senescent cells can substantially contribute to pathological conditions and accelerate disease exacerbation, particularly cancer resistance, relapse and metastasis.
