Radiosensitivity Parameters for Neoplastic Transformations in C3H10T1/2 Cells

Radiation Research, 1987
We have evaluated radiosensitivity parameters for cellular transformation from published experimental data on neoplastic transformations induced in C3H10T1/2 cells by BEVALAC ions. The measured RBE values are well reproduced by a track theory calculation using sets of m-target parameters with either m = 2 or m = 3, suggesting a quadratic or cubic ...

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

Molecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

KRT14 marks a subpopulation of bladder basal cells with pivotal role in regeneration and tumorigenesis

Nature Communications, 2016
It is unclear whether there is a progenitor/stem cell in the basal layer of the urothelium in the bladder. Here, the authors identify Keratin14 positive cells that can regenerate the bladder in both a natural and injury-induced manner, and following ...

On the Origin of Pancreatic Endocrine Cells, Proliferation and Neoplastic Transformation

Tumor Biology, 1993
In the adult mouse, pancreatic islets contain four islet cell types: alpha, beta, delta and pancreatic polypeptide cells that synthesize glucagon, insulin, somatostatin and pancreatic polypeptide, respectively. The early progenitor cells to the pancreatic islets are multipotential and coactivate all the islet-specific genes from the time they first ...

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

FRA1 (FOSL1) suppresses neoplastic transformation and modulates radiation responses via transcriptional control of mitogenic and stress-responsive networks

Frontiers in Cell and Developmental Biology
PurposeFOS-like antigen 1 (FRA1), encoded by FOSL1, is an inducible subunit of the AP-1 transcription factor complex and regulates gene expression in response to proliferative and environmental cues.

Glioblastoma-Derived Extracellular Vesicles Facilitate Transformation of Astrocytes via Reprogramming Oncogenic Metabolism

iScience, 2020
Summary: Glioblastoma (GBM) may arise from astrocytes through a multistep process involving a progressive accumulation of mutations. We explored whether GBM-derived extracellular vesicles (EVs) may facilitate neoplastic transformation and malignant ...

Mechanisms of radiation-induced neoplastic cell transformation [PDF]

, 1984
Studies with cultured mammalian cells demonstrated clearly that radiation can transform cells directly and can enhance the cell transformation by oncogenic DNA viruses. In general, high-LET heavy-ion radiation can be more effective than X and gamma rays in inducing neoplastic cell transformation.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.
