The cysteine, total sulfur amino acid, tyrosine, phenylalanine + tyrosine, and non-essential amino acid maintenance requirements of broiler breeders

open access: yesPoultry Science, 2016
Two hundred and fifty Cobb-Vantress broiler breeders were used to determine the maintenance requirement and efficiency of utilization of dietary Cys, Tyr, and non-essential amino acids (AA) in a 21-day experiment. The breeders were fed crystalline amino acid diets containing graded levels of Cys or Tyr representing 0, 10, 20, 30, and 40% of their ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Changes in the Amino Acid Composition of Bee-Collected Pollen During 15 Months of Storage in Fresh-Frozen and Dried Forms

open access: yesFoods
Bee pollen (BP) is a nutritionally valuable natural product whose biological activity is strongly influenced by its amino acid profile. This study evaluated qualitative and quantitative changes in free amino acids in Lithuanian BP subjected to freezing (−

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Effect of essential and non-essential amino acid supplementation in canine nutrition

open access: yesRevista de Investigaciones Veterinarias del Perú, 2023
The study evaluated the effect of a nutritional supplement (composed of the 10 essential and eight non-essential amino acids) and a commercial vitamin supplement on body weight and body condition of 44 malnourished dogs (body condition 1 and 2). The animals were weighed and evaluated on days 1, 7 and 14 of treatment.

Serine Metabolism in Health and Disease and as a Conditionally Essential Amino Acid

open access: yes, 2022
L-serine plays an essential role in a broad range of cellular functions including protein synthesis, neurotransmission, and folate and methionine cycles and synthesis of sphingolipids, phospholipids, and sulphur containing amino acids.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Amino Acid Transport Assays in Resting Cells of Lactococcus lactis

open access: yesBio-Protocol, 2013
Many bacteria are auxotrophic for at least a number of amino acids for which they lack the biosynthetic pathways. The organisms are still able to grow in media containing free amino acids as the sole source of amino acid when transport systems for the ...
