Targeted protein degradation using chimeric human E2 ubiquitin-conjugating enzymes.

Proteins can be targeted for degradation by engineering biomolecules that direct them to the eukaryotic ubiquitination machinery. For instance, the fusion of an E3 ubiquitin ligase to a suitable target binding domain creates a 'biological Proteolysis-Targeting Chimera' (bioPROTAC). Here we employ an analogous approach where the target protein is recruited directly to a human E2 ubiquitin-conjugating enzyme via an attached target binding domain.

The Birth and Development of the Lactation Consultant Profession (1980-2007): An Interview With Chele Marmet (Part II).

The remarkable world-changing growth of (globally over 35,000 IBCLCs in 2023), as the internationally recognized lactation professional since Chele Marmet conceptualized the field in 1977, demonstrates its importance for society and breastfeeding dyads. The early 1980s was a seminal time in the development of lactation care as a allied health field with specialized knowledge, study, and certification. Chele Marmet played a significant role as an innovator and activist during all these major changes.

The Conception and Birth of the Lactation Consultant Profession (1977-1983): An Interview With Chele Marmet (Part I).

In 2015, Miriam Labbok, MD, MPH, entrusted Chele Marmet with the task of writing a chapter on the early history of the lactation consultant profession for the public health textbook she was preparing about lactation, saying, "I invited you to author it because you conceptualized and pioneered the profession, and there is nobody else I could ask who could do it justice," (M. Labbok, personal communication, June 28, 2015). Chele Marmet envisioned the allied health field of lactation consulting, complete with international educational standards, professional organizations, and a scope of practice.

Brown and beige adipose tissue regulate systemic metabolism through a metabolite interorgan signaling axis.

Brown and beige adipose tissue are emerging as distinct endocrine organs. These tissues are functionally associated with skeletal muscle, adipose tissue metabolism and systemic energy expenditure, suggesting an interorgan signaling network. Using metabolomics, we identify 3-methyl-2-oxovaleric acid, 5-oxoproline, and β-hydroxyisobutyric acid as small molecule metabokines synthesized in browning adipocytes and secreted via monocarboxylate transporters.

An Intergenerational Exploration of Breastfeeding Journeys Through the Lens of African American Mothers and Grandmothers.

Background: Many individuals comprise a nursing mother's social support network. Grandmothers within African American families, historically, have played a vital role in the transmission of culture. Understanding intergenerational perspectives within African American families related to infant feeding and scholarship about breastfeeding is critical, given the breastfeeding patterns among African American women.

characterization of the effects of chronic insulin stimulation in mouse 3T3-L1 and human SGBS adipocytes.

Hyperinsulinemia is the hallmark of the development of insulin resistance and precedes the diagnosis of type 2 diabetes. Here we evaluated the effects of prolonged exposure (≥4 days) to high insulin doses (150 nM) in two adipose cell types, mouse 3T3-L1 and human SGBS. Chronic insulin treatment significantly decreased lipid droplet size, insulin signalling and insulin-stimulated glucose uptake.

Bioprospecting for Antibacterial Drugs: a Multidisciplinary Perspective on Natural Product Source Material, Bioassay Selection and Avoidable Pitfalls.

Bioprospecting is the exploration, extraction and screening of biological material and sometimes indigenous knowledge to discover and develop new drugs and other products. Most antibiotics in current clinical use (eg. β-lactams, aminoglycosides, tetracyclines, macrolides) were discovered using this approach, and there are strong arguments to reprioritize bioprospecting over other strategies in the search for new antibacterial drugs.
