(RS16) Intake of Calcium and Vitamin D in Patients with Disorders of Amino Acid Metabolism Prescribed with Metabolic Formulas – Are We Giving Enough for Bone Health?

open access: yes, 2022
Introduction: Patients with disorders of amino acid metabolism (AAMD) such as aminoacidopathies (AA), organic acidurias (OA) and urea cycle disorders (UCD) are at an increased risk for bone disease due to a restriction of high protein foods rich in ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

The effect of hyperthermia on the phosphoinositide signalling system of tumour cells [PDF]

open access: yes, 1994
The effect of heat on the phosphoinositide signalling pathway was investigated in CHO-K1 cells and WRK-1 cells. Heat caused a decrease in 1,2-diacylglycerol (1,2- DAG) levels but did not have any effect on monoacylglycerol (MAG) levels in both cell types.

open access: yesОстеопороз и остеопатии, 2010
Calcium-sensing receptor (CaSR), a member of G proteincoupled receptors family, plays a key role in systemic calcium homeostasis regulation. It is expressed in a variety of tissues, and is responsible for maintaining plasma calcium concentration.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Calcium and Metabolic Bone Disorders

open access: yes, 2021
Calcium homeostasis has a pivotal role in regulating many biological processes. The interplay of calcium-regulating hormones, including parathyroid hormone (PTH), vitamin D, and calcitonin, is crucial in tightly maintaining serum calcium levels. Deregulation of calcium homeostasis has clinical implications resulting in hypercalcemia or hypocalcemia ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

open access: yesFEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Bone and Calcium Metabolism in Subclinical Autoimmune Hyperthyroidism and Hypothyroidism

open access: yes, 2003
Bone turnover is reported to increase in favour of resorption in overt hyperthyroidism and the rate of resorption is associated with the levels of thyroid hormones.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs
