To model this property of recessive lethals, we retained only replicates that were consistent with this condition, i.e., replicates where all individuals with offspring were either heterozygous or homozygous for the beneficial allele.
In summary, while many analogs retained lethal activity (three examples of lethal compounds are shown in Figure 6A), none of the 87 analogs could trigger ferroptosis with enhanced selectivity for β-ME and Fer-1-suppressible death over other lethal mechanisms compared to the parent compound itself.
Representative data are shown for three analogs that retained lethal activity SRS13-455, SRS13-47, SRS13-47) and four analogs that lost lethal activity SRS13-677, SRS14-98, SRS14-98, SRS15-11) in the cell-based assay.
Whereas most drugs lost their activity, fluoroquinolones retained lethal potency.
It is thought that the potentially lethal thalassemia gene is retained in certain populations because it provides some protection from malaria in the heterozygous state.
Lethal ended up retaining the title at the event.
Subsequent studies of genetically modified mice revealed that while bi-allelic loss of Becn1 is embryonically lethal, mice that retain one copy of the gene are viable, but have a higher incidence of lymphomas, lung and liver carcinomas, as well as mammary hyperplasia and accelerated formation of premalignant lesions induced by hepatitis B virus, compared with wild-type animals (Refs 34, 35).
Actually, while impact force and exposure time to dusty gas dropped below lethal conditions, the pyroclastic cloud retained its high temperature thus being the main cause of instantaneous mortality for the Vesuvius area inhabitants, including people who were sheltered within buildings as far as in Pompeii.
While 14 was inactive, we found that both lethal analogs (21 and 3) retained selectivity towards BJeLR vs BJeH cells.
