One of the best-known stem cell paper is being withdrawn due to flawed data according to New Scientist. This has angered some researchers including Jeanne Loring, a stem cell biologist at the Burnham Institute for Medical Research in La Jolla, California. She states, “if I had been following this recipe since 2002, I’d be extremely angry.”

Katherine Schaefer and her colleagues at the University of Rochester Medical Center in New York believe they have discovered a new way to attack tumors that have learned how to evade existing drugs. However, that’s not what makes this article so interesting. According to a MSNBC article, the discovery was not from years of research, but from a lab disaster.

MSNBC writes

She was testing a compound called a PPAR-gamma modulator. It would never normally have been thought of as a cancer drug, or in fact a drug of any kind.

“I made a calculation error and used a lot more than I should have. And my cells died,” Schaefer said.

A colleague overheard her complaining. “The co-author on my paper said,’ Did I hear you say you killed some cancer?’ I said ‘Oh’, and took a closer look.”

They ran several tests and found the compound killed ”pretty much every epithelial tumor cell lines we have seen,” Schaefer said. Epithelial cells line organs such as the colon, and also make up skin.

It also killed colon tumors in mice without making the mice sick, they reported in the journal International Cancer Research.

Section 505 of the Food Drug and Cosmetic Act (the Act) describes three types of new drug applications: (1) an application that contains full reports of investigations of safety and effectiveness (section 505(b)(1)); (2) an application that contains full reports of investigations of safety and effectiveness but where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference (section 505(b)(2)); and (3) an application that contains information to show that the proposed product is identical in active ingredient, dosage form, strength, route of administration, labeling, quality, performance characteristics, and intended use, among other things, to a previously approved product (section 505(j)). Section 505(b)(2) was added to the Act by the Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Amendments). This provision expressly permits FDA to rely, for approval of an NDA, on data not developed by the applicant. Sections 505(b)(2) and (j) together replaced FDA’s paper NDA policy, which had permitted an applicant to rely on studies published in the scientific literature to demonstrate the safety and effectiveness of duplicates of certain post-1962 pioneer drug products (see 46 FR 27396, May 19, 1981). Enactment of the generic drug approval provision of the Hatch-Waxman Amendments ended the need for approvals of duplicate drugs through the paper NDA process by permitting approval under 505(j) of duplicates of approved drugs (listed drugs) on the basis of chemistry and bioequivalence data, without the need for evidence from literature of effectiveness and safety. Section 505(b)(2) permits approval of applications other than those for duplicate products and permits reliance for such approvals on literature or on an Agency finding of safety and/or effectiveness for an approved drug product.

According to an article published in the British Medical Journal (2007;334:245-248), a study was performed to examine the relation between IQ in childhood and vegetarianism in adulthood. The investigation was a prospective cohort study in which IQ was assessed by tests of mental ability at age 10 years and vegetarianism by self-report at age 30 years. Study participants included 8,170 men and women aged 30 years, who took part in the 1970 British cohort study, a national birth cohort. The main outcome measures were self-reported vegetarianism and type of diet followed. Results showed that 366 (4.5%) persons said they were vegetarian, although 123 (33.6%) admitted eating fish or chicken. Vegetarians were more likely to be female, to be of higher social class (both in childhood and currently), and to have attained higher academic or vocational qualifications. Interestingly, these socioeconomic advantages were not reflected in their income. Higher IQ at age 10 years was associated with an increased likelihood of being vegetarian at age 30 (odds ratio (OR) for one standard deviation increase in childhood IQ score 1.38). IQ remained a statistically significant predictor of being vegetarian as an adult after adjustment for social class (both in childhood and currently), academic or vocational qualifications, and gender (OR = 1.20). Exclusion of those who said they were vegetarian but ate fish or chicken had little effect on the strength of this association. According to the authors, higher scores for IQ in childhood are associated with an increased likelihood of being a vegetarian as an adult.

This video is in Japanese, but it can be understood without knowing Japanese. I personally don’t know if there’s any formal study conducted, but this technique has been tested by a scientist sponsored by the TV show.
