Summary
Biomineralisation uses calcium and phosphate to build hard tissues. In renal failure, these processes are disrupted, causing harmful crystal buildup and bone mineral loss.
Area of Science:
- Biochemistry
- Biomineralization
- Skeletal Biology
Background:
- Calcium and phosphate precipitate to form insoluble compounds, a process vital for biomineralization in organisms.
- In humans, calcium hydroxyapatite forms essential hard tissues like bone and teeth.
- Dysregulation of biomineralization pathways in aging and disease leads to ectopic calcification and mineral loss.
Purpose of the Study:
- To investigate the mechanisms of biomineralization specificity in humans.
- To understand the perturbations in calcium and phosphate pathways in renal failure.
- To explore the concept of mineral trafficking in bone mineral disease.
Main Methods:
- Literature review on biomineralization and renal failure.
- Analysis of mineral deposition and loss in aging and disease states.
- Conceptual framework development for mineral trafficking.
Main Results:
- Biomineralization is crucial for skeletal integrity but its specificity is not fully understood.
- Renal failure exemplifies perturbed mineral pathways, leading to vascular calcification and bone demineralization.
- Mineral trafficking offers a new perspective on bone mineral disease in renal failure.
Conclusions:
- Understanding biomineralization specificity is key to addressing mineral dysregulation.
- Renal failure highlights the complex interplay between systemic mineral balance and tissue health.
- Investigating mineral trafficking may reveal novel therapeutic targets for bone and vascular diseases.

00:51Synthesis and Functions of Calcitonin
5.2K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

01:27Roles of Electrolytes: Calcium and Phosphate
2.2K
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.

01:31Essential Minerals for Bone Health
7.0K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:16Calmodulin-dependent Signaling
7.0K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

01:21Skeleton and Calcium Homeostasis
7.2K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:33Overview of Secretory Vesicles
9.8K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...
