Molecular Profiling Identifies CD49d and CD79b as Predictive Markers for Acquired Acalabrutinib Resistance in Patients With Chronic Lymphocytic Leukemia.

Contemporary studies of Bruton tyrosine kinase inhibitor (BTKi) resistance focus on mutations in the B-cell receptor (BCR) pathway, but alternative mechanisms of resistance remain undefined. Here, we sought to identify novel predictive markers of acquired resistance to acalabrutinib, a second-generation BTKi, in patients with chronic lymphocytic leukemia (CLL). Clinical samples from 41 patients with relapsed/refractory or treatment-naive CLL receiving acalabrutinib as part of a clinical trial (NCT02029443) were divided into two groups: those who continued to respond to treatment (NP, n = 23) and those who developed progressive disease on acalabrutinib therapy (PD, n = 18).

The effects of listening on speaker and listener while talking about character strengths: an open science school-wide collaboration.

Listening is understood to be a foundational element in practices that rely on effective conversations, but there is a gap in our understanding of what the effects of high-quality listening are on both the speaker and listener. This registered report addressed this gap by training one group of participants to listen well as speakers discuss their character strengths, allowing us to isolate the role relational listening plays in strengths-based conversations. Participants were paired and randomly assigned to a high-quality listening (experimental) or moderate-quality listening (comparison) condition manipulated through a validated video-based training.

Opposing regulation of endoplasmic reticulum retention under stress by ERp44 and PDIA6.

Conditions of endoplasmic reticulum (ER) stress reduce protein synthesis by provoking translation regulation, governed by the eIF2α kinase PERK. When PERK is inhibited during ER stress, retention of a selective subset of glycoproteins occurs, a phenomenon we termed selective ER retention (sERr). sERr clients are enriched with tyrosine kinase receptors (RTKs), which form large molecular weight disulfide bonded complexes in the ER.

The role of IL-1 family cytokines in diabetic cardiomyopathy.

Diabetic cardiomyopathy (DCM) is the primary cause of heart failure in patients with diabetes and is characterised by contractile dysfunction and left ventricular hypertrophy. The complex pathological and physiological mechanisms underlying DCM have contributed to a limited number of available treatment options. A substantial body of evidence has established that DCM is a low-grade inflammatory cardiovascular disorder, with the interleukin-1 (IL-1) family of cytokines playing crucial roles in initiating inflammatory responses and shaping innate and adaptive immunity.
