Comment: One of the Most Widely Used Methods in Epigenetics Can Cause Misleading Results

Dear Dr. Nebert, this is a very interesting paper – thank you. I agree with the authors, for most part. In addition to the weakness that they reported, I think DIP-seq has its inherent drawbacks. Without bisulfite modification, the methylation … Continue reading

How the LNT Model became the default model for cancer risk assessment — based on a published study that likely was never peer-reviewed

These two very recent publications [see attached] are the latest in a long series –– on the topic of the Linear No-Threshold (LNT) Model, which (since about 2o11) has been carefully dissected historically by Ed Calabrese (School of Public Health, … Continue reading

One of the Most Widely Used Methods in Epigenetics Can Cause Misleading Results

We also learned a similar lesson regarding artifacts through the history of proteomics technologies –– particularly from protein-interactions studies that rely on immunoprecipitation as the first step. This ultimately led to a database of “usual suspects” that was later more … Continue reading

One of the Most Widely Used Methods in Epigenetics Can Cause Misleading Results

This BREAKTHROUGH paper (reported today in FRONTLINE GENOMICS) is very important to those in the field (e.g. Sean Zhang), so I have moved it “to the front of the QUEUE.” There is nothing worse than spending a lot of time, … Continue reading

Moving on into a New Frontier: “3-dimensional genomics” (the way the chromosomes are situated in the nucleus)

As these GEITP pages keep harping on –– the factors that contribute to any trait (response to a drug or environmental toxicant, hair color, height, blood pressure, risk of type-2 diabetes, risk of autism spectrum disorder, etc.) include: genotype (DNA … Continue reading

June Solar Update

This is just what my late son had been interested in, and predicting, since about 2000. (It was part of his job.) Solar activity (sunspot frequency) has become incredibly quiet during Cycles 23 and especially Cycle 24. The last time … Continue reading

How did Life begin?

his topic is a bit on the periphery of ‘Gene-Environment Interactions,’ but –– without Life on Earth –– we wouldn’t have genes to interact with the environment. 🙂 How and Why did Life come to exist on this planet? Is … Continue reading

What allows TEMPERATURE (of the environment) to influence the developmental pathways that determine sex?

It is well known that the sex (i.e. whether it’s male or female gender) of certain reptiles can be determined by ambient temperatures of the environment, although the precise molecular mechanism has remained elusive. What is it –– that allows … Continue reading
