Summary
This study details the outcomes of replicating preclinical cancer biology experiments. Many attempts faced challenges, highlighting difficulties in repeating scientific findings and assessing reproducibility in cancer research.
Area of Science:
- Preclinical Cancer Biology
- Scientific Reproducibility
Background:
- The Reproducibility Project: Cancer Biology aimed to replicate experiments from high-impact preclinical cancer studies.
- Previous phases reported on 18 of 29 targeted papers, with 17 published by eLife.
Purpose of the Study:
- To report the status and outcomes of replication attempts for the remaining 11 preclinical cancer biology papers.
- To provide evidence on the challenges and replicability of preclinical cancer experiments.
Main Methods:
- Replication experiments were initiated for 11 selected preclinical cancer biology papers.
- Experimental work was stopped or faced challenges in all 11 cases, preventing full completion.
Main Results:
- Four papers had experimental work stopped without outcomes.
- Two papers yielded incomplete outcomes due to unforeseen experimental challenges.
- Five papers had only partial experiments completed due to technical or methodological issues.
Conclusions:
- Repeating preclinical cancer biology experiments presents significant challenges.
- The outcomes underscore difficulties in achieving full experimental replication in this field.

Mouse Models of Cancer Study
5.8K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Cancers Originate from Somatic Mutations in a Single Cell
13.2K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
