“Are we not Men?”: Reading the Human-Animal Interface in Science Fiction through John Berger’s “Why Look at Animals?”

The so-called animal turn in literature has fostered the evolution of animal studies, a discipline aimed at interrogating the ontological, ethical, and metaphysical implications of animal depictions. Animal studies deals with representation and agency in literature, and its insights have fundamental implications for understanding the conception and progression of human-animal interactions. Considering questions raised by animal studies in the context of literary depictions of animals in science fiction, this article threads John Berger’s characterization of the present as a time of radical marginalization of animals in his essay “Why Look at Animals?” through two highly influential science fiction texts: H. G. Wells’s The Island of Doctor Moreau and Philip K. Dick’s Do Androids Dream of Electric Sheep?. Applying Berger’s reasoning to these two novels raises issues of personhood, criteria for ontological demarcation, and the dynamics of power, providing an opportunity to clarify, modify, and refute a number of his finer claims. This process of refinement allows us to track conceptions of human-animal interactions through the literary landscape and explore their extrapolations into various speculative contexts, including the frontiers of science and post-apocalyptic worlds

DMD-associated dilated cardiomyopathy : genotypes, phenotypes, and phenocopies

Background: Variants in the DMD gene, that encodes the cytoskeletal protein, dystrophin, cause a severe form of dilated cardiomyopathy (DCM) associated with high rates of heart failure, heart transplantation, and ventricular arrhythmias. Improved early detection of individuals at risk is needed. Methods: Genetic testing of 40 male probands with a potential X-linked genetic cause of primary DCM was undertaken using multi-gene panel sequencing, multiplex polymerase chain reaction, and array comparative genomic hybridization. Variant location was assessed with respect to dystrophin isoform patterns and exon usage. Telomere length was evaluated as a marker of myocardial dysfunction in left ventricular tissue and blood. Results: Four pathogenic/likely pathogenic DMD variants were found in 5 probands (5/40: 12.5%). Only one rare variant was identified by gene panel testing with 3 additional multi-exon deletion/duplications found following targeted assays for structural variants. All of the pathogenic/likely pathogenic DMD variants involved dystrophin exons that had percent spliced-in scores >90, indicating high levels of constitutive expression in the human adult heart. Fifteen DMD variant-negative probands (15/40: 37.5%) had variants in autosomal genes including TTN, BAG3, LMNA, and RBM20. Myocardial telomere length was reduced in patients with DCM irrespective of genotype. No differences in blood telomere length were observed between genotype-positive family members with/without DCM and controls. Conclusions: Primary genetic testing using multi-gene panels has a low yield and specific assays for structural variants are required if DMD-associated cardiomyopathy is suspected. Distinguishing X-linked causes of DCM from autosomal genes that show sex differences in clinical presentation is crucial for informed family management. © 2023 American Heart Association, Inc

Only very few examples of digenic inheritance have been described in the neuromuscular disease field. Here we show that predicted deleterious variants in SRPK3, encoding the X-linked serine/argenine protein kinase 3, lead to a progressive early onset skeletal muscle myopathy only when in combination with heterozygous variants in the TTN gene. The co-occurrence of predicted deleterious SRPK3/TTN variants was not seen among 76,702 healthy male individuals, and statistical modeling strongly supported digenic inheritance as the best-fitting model. Furthermore, double-mutant zebrafish (srpk3-/-; ttn.1+/-) replicated the myopathic phenotype and showed myofibrillar disorganization. Transcriptome data suggest that the interaction of srpk3 and ttn.1 in zebrafish occurs at a post-transcriptional level. We propose that digenic inheritance of deleterious changes impacting both the protein kinase SRPK3 and the giant muscle protein titin causes a skeletal myopathy and might serve as a model for other genetic diseases
