‘Mental illness: the collision of meaning with mechanism’ is based on the views of psychiatry that Steven Hyman articulated in his Loebel Lectures—mental illness results from the disordered functioning of the human brain and effective treatment repairs or mitigates those malfunctions. This view is not intended as reductionist as causes of mental illness and contributions to their repair may come from any source that affects the structure and function of the brain. These might include social interactions and other sources of lived experience, ideas (such as those learned in cognitive therapy), gene sequences and gene regulation, metabolic factors, drugs, electrodes, and so on. This, however, is not the whole story for psychiatry on Hyman’s view; interpersonal interactions between clinicians and patients, intuitively understood in such folk psychological terms as selfhood, intention, and agency are also critical for successful practice. As human beings who are suffering, patients seek to make sense of their lives and benefit from the empathy, respect, and a sense of being understood not only as the objects of a clinical encounter, but also as subjects. Hyman’s argument, however, is that the mechanisms by which human brains function and malfunction to produce the symptoms and impairments of mental illness are opaque to introspection and that the mechanistic understandings necessary for diagnosis and treatment are incommensurate with intuitive (folk psychological) human self-understanding. Thus, psychiatry does best when skillful clinicians switch between an objectifying medical and neurobiological stance and the interpersonal stance in which the clinician engages the patients as a subject. Attempts to integrate these incommensurate views of patients and their predicaments have historically produced incoherent explanations of psychopathology and have often led treatment astray. For example, privileging of folk psychological testimony, even when filtered through sophisticated theories has historically led psychiatry into intellectually blind and clinically ineffective cul-de-sacs such as psychoanalysis.

RNA tails play integral roles in the regulation of messenger RNA (mRNA) translation and decay. Guanylation of the poly(A) tail was discovered recently, yet the enzymology and function remain obscure. Here we identify TENT4A (PAPD7) and TENT4B (PAPD5) as the enzymes responsible for mRNA guanylation. Purified TENT4 proteins generate a mixed poly(A) tail with intermittent non-adenosine residues, the most common of which is guanosine. A single guanosine residue is sufficient to impede the deadenylase CCR4-NOT complex, which trims the tail and exposes guanosine at the 3′ end. Consistently, depletion of TENT4A and TENT4B leads to a decrease in mRNA half-life and abundance in cells. Thus, TENT4A and TENT4B produce a mixed tail that shields mRNA from rapid deadenylation. Our study unveils the role of mixed tailing and expands the complexity of posttranscriptional gene regulation.

Bone morphogenetic proteins (BMPs) were once considered only to have a role in bone formation. It is now known that they have pivotal roles in other organ diseases, including heritable pulmonary arterial hypertension (PAH), where genetic mutations in the type II BMP receptor (BMPR2) are the commonest cause of receptor dysfunction. However, it has also recently been demonstrated that aquaporin 1 (Aqp1) dysfunction may contribute to PAH, highlighting that PAH development may involve more than one pathogenic pathway. Whether reduction in BMPR2 affects Aqp1 is unknown. We therefore studied Aqp1 in BMPR2-silenced human pulmonary microvascular endothelial cells (HPMECs). We demonstrated reduced Aqp1 mRNA, protein, and function in the BMPR2-silenced cells. Additionally, BMPR2-silenced cells exhibited lower expression of BMP-signaling molecules. In conclusion, decreased BMPR2 appears to affect Aqp1 at the mRNA, protein, and functional levels. This observation may identify a contributory mechanism for PAH.
