I wasn't too surprised to learn that Hasletine had also gotten this crazy idea1 published in the scientific literature.
Haseltine, W.A. and Patarca, R. (2024) The RNA revolution in the central molecular biology dogma evolution. International Journal of Molecular Sciences 25:12695. doi: [doi: 10.3390/ijms252312695]
Human genome projects in the 1990s identified about 20,000 protein-coding sequences. We are now in the RNA revolution, propelled by the realization that genes determine phenotype beyond the foundational central molecular biology dogma, stating that inherited linear pieces of DNA are transcribed to RNAs and translated into proteins. Crucially, over 95% of the genome, initially considered junk DNA between protein-coding genes, encodes essential, functionally diverse non-protein-coding RNAs, raising the gene count by at least one order of magnitude. Most inherited phenotype-determining changes in DNA are in regulatory areas that control RNA and regulatory sequences. RNAs can directly or indirectly determine phenotypes by regulating protein and RNA function, transferring information within and between organisms, and generating DNA. RNAs also exhibit high structural, functional, and biomolecular interaction plasticity and are modified via editing, methylation, glycosylation, and other mechanisms, which bestow them with diverse intra- and extracellular functions without altering the underlying DNA. RNA is, therefore, currently considered the primary determinant of cellular to populational functional diversity, disease-linked and biomolecular structural variations, and cell function regulation. As demonstrated by RNA-based coronavirus vaccines’ success, RNA technology is transforming medicine, agriculture, and industry, as did the advent of recombinant DNA technology in the 1980s.
What surprised me was a comment by John Harshman who pointed out that the International Journal of Molecular Sciences is one of many journals published by MDPI and this company has been identified as a predatory open access publishing company. [Is MDPI Predatory?] Predatory publishing companies will publish almost anything with very little peer review or editing.
One of the characteristic features of such predatory journals is a very fast turnaround from the time of submission to publication. For example, the Haseltine and Patarca paper was received on November 11, 2024, revised on Nov. 24, 2024, accepted on Nov. 25, 2024, and published the next day. The time from submission to publication was 15 days! No reasonable person could possibly believe that it was adequately reviewed by experts in the field.
I'm very much aware of the spread of misinformation in the scientific literature but I didn't realize that fake scientific journals could be contributing to that spread and I certainly never thought that a (formerly) respected scientist would actually publish in such a journal.
1. The crazy idea is that scientists in the 1960s and 1970s didn't know about regulatory sequences and non-coding genes. Haseltine was there; his Ph.D. supervisors were Jim Watson and Wally Gilbert and he did his postdoc with David Baltimore. The other part of the crazy idea is that the central dogma was all about proteins being the only important thing that was specified by DNA. That's not correct. It is not a "paradigm" that has to be overthrown by recent discoveries. The third part of the crazy idea is that there are more non-coding genes than protein coding genes. That has not been demonstrated and it's very unlikely that we are ever going to find solid evidence for more than 20,000 non-coding genes.
