Growth‐regulating proteins differ between British seawater fish species, shedding light on their ecological adaptations

Journal of Fish Biology, EarlyView.
Abstract Wnt proteins are a family of molecules that help control how cells grow, develop and communicate – processes that are fundamental to the development and health of all animals. Although Wnt pathways have been studied extensively in model species, very little is known about how they operate in marine fish.

RAC1 promotes the occurrence and development of tongue squamous cell carcinoma by regulating RAC1/PAK1/LIMK1 signaling pathway

Scientific Reports
Tongue squamous cell carcinoma (TSCC) remains an unsolved medical problem due to its poor local recurrence rate and prognosis. The purpose of this study was to investigate the expression characteristics of RAC-related C3 botulinum toxin substrate 1(RAC1)

One minute of light‐intensity stair‐stepping decreases postprandial glycaemia in the evening in non‐diabetic adults: A randomized controlled trial

Experimental Physiology, EarlyView.
Abstract Prior studies have investigated the efficacy of a single 1 min bout of stair‐stepping on reducing postprandial blood glucose (BG) in the morning, but none have investigated this effect in the evening when glycaemic responses are larger due to circadian regulation and β‐cell responsiveness. This work investigated the efficacy of a 1 min bout of

In vitro muscle contraction: A technical review on electrical pulse stimulation in C2C12 cells

Experimental Physiology, EarlyView.
Abstract Electrical pulse stimulation (EPS) of skeletal muscle cells is increasingly used to model exercise In vitro. The murine C2C12 myotube system has become a common platform for such studies, yet wide variability in EPS protocols hampers reproducibility and cross‐study comparisons.

Circulating RAC1 contributed to steroid-sensitive nephrotic syndrome: Mendelian randomization, single-cell RNA-sequencing, proteomic, and experimental evidence

Renal Failure
Objectives The small GTPase Rac1 (RAC1) has been linked to podocyte disorders and steroid-sensitive nephrotic syndrome (SSNS). The aim of this study was to explore and validate the potential causal association between circulating RAC1 and SSNS.Methods ...

The RhoA guanine exchange factor ABR: a glucose‐sensitive mediator of actin reorganization in feto‐placental arterial endothelial cells altered by gestational diabetes mellitus

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of proposed relationship between hyperglycaemia, gestational diabetes mellitus (GDM), active BCR‐related (ABR), RhoA and actin organization of feto‐placental arterial endothelial cells (fpEC). Hyperglycaemia upregulates ABR, which in turn increases RhoA activation.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

Dynamic cofilin phosphorylation in the control of lamellipodial actin homeostasis [PDF]

, 2007
During animal cell chemotaxis, signalling at the plasma membrane induces actin polymerisation to drive forward cell movement. Since the cellular pool of actin is limited, efficient protrusion formation also requires the coordinated disassembly of pre ...
