Equilibrium self‐association of tropomyosin [PDF]

FEBS Letters, 2012
It has recently been reported that tropomyosin exists exclusively as a dimer in physiological salt conditions. It is shown in the present work using analytical ultracentrifugation that, on the contrary, tropomyosin is in equilibrium between monomer, dimer and tetramer with a weak tendency to dimerize and tetramerize. Such a finding has consequences for

MAGEA6 Engages a YY1‐Dependent Transcription to Dictate Perineural Invasion in Colorectal Cancer

Advanced Science, EarlyView.
This study investigates the role of MAGEA6 in perineural invasion (PNI) in colorectal cancer (CRC). MAGEA6 promotes CRC invasiveness by inhibiting YY1 ubiquitination, enhancing CXCL1 secretion, and recruiting Schwann cells. These findings highlight the potential of targeting the MAGEA6/YY1/CXCL1 axis for therapeutic strategies against PNI and tumor ...

Interaction of actin with dansyl‐tropomyosin [PDF]

FEBS Letters, 1986
5‐[Dimethylamino]naphthalene‐1‐sulfonyl chloride (dansyl chloride) reacts with rabbit skeletal muscle tropomyosin (TM) to yield a highly fluorescent product, DNS‐TM. The extent of modification of TM can be regulated over a wide range, 0.3–15.5 dansyl groups per TM, depending upon the temperature and duration of the reaction.

Disruption of the blood–brain barrier contributes to neurobehavioral changes observed in rheumatic heart disease

Animal Models and Experimental Medicine, EarlyView.
Sydenham's chorea (SC) is the neurological manifestation associated with acute rheumatic fever (ARF), triggered by a group A streptococcal (GAS) infection. Anti‐GAS antibodies cross‐reacting with tissue proteins are implicated in the development of neurological changes. In this study, using an animal model, we demonstrate that a compromised blood–brain

Reduction in Allergenicity and Induction of Oral Tolerance of Glycated Tropomyosin from Crab

Molecules, 2022
Tropomyosin (TM) is an important crustacean (Scylla paramamosain) allergen. This study aimed to assess Maillard-reacted TM (TM-G) induction of allergenic responses with cell and mouse models. We analyzed the difference of sensitization and the ability to

Decreasing Tropomyosin Phosphorylation Rescues Tropomyosin-induced Familial Hypertrophic Cardiomyopathy [PDF]

Journal of Biological Chemistry, 2013
Studies indicate that tropomyosin (Tm) phosphorylation status varies in different mouse models of cardiac disease. Investigation of basal and acute cardiac function utilizing a mouse model expressing an α-Tm protein that cannot be phosphorylated (S283A) shows a compensated hypertrophic phenotype with significant increases in SERCA2a expression and ...

Association of Synovial Innate Immune Exhaustion With Worse Pain in Knee Osteoarthritis

Arthritis &Rheumatology, EarlyView.
Objective Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune‐regulatory cells in pain is unknown. Our objective was to identify synovial innate immune

Establishment of an Epicutaneously Sensitized Murine Model of Shellfish Allergy and Evaluation of Skin Condition by Raman Microscopy

Applied Sciences, 2022
Background: Shellfish allergy is one of the most common food allergies. Recent studies have shown that sensitization to allergens via the skin is involved in the development of food allergies.

Modeling Suggests Combined-Drug Treatments for Disorders Impairing Synaptic Plasticity via Shared Signaling Pathways [PDF]

arXiv, 2020
Genetic disorders such as Rubinstein-Taybi syndrome (RTS) and Coffin-Lowry syndrome (CLS) cause lifelong cognitive disability, including deficits in learning and memory. Can pharmacological therapies be suggested to improve learning and memory in these disorders?

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
