What is Homeostasis?

What is Homeostasis?

Maintaining homeostasis requires that the body continuously maintain its internal conditions. Each physiological condition has a particular set point, from body temperature to blood pressure to levels of certain nutrients. A set point is the physiological value around which the normal range fluctuates. A normal range is a restricted set of values that is optimally healthful and stable. For example, the set point for normal human body temperature is approximately 37°C (98.6°F).

pH Homeostasis

pH Homeostasis

Acid-base homeostasis is essential for maintaining normal physiological activities in humans. The pH of various body fluids is strictly regulated because it is critical for the optimal activity of enzymes involved in metabolic reactions. Enzymes are basically proteins, so, any significant change in pH can affect their structure and activity. In humans, pH is regulated using three primary mechanisms— chemical buffer systems, respiratory regulation, and renal regulation.

Autophagic Cell Death

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Overview of Cell Death

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

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.

Background:

Mitochondria are central to cellular energy production and reactive oxygen species generation.
Mitochondrial network structure, maintained by fission and fusion, governs cell life and death.
Key proteins like Drp1, Mfn1/2, and OPA1 regulate mitochondrial shape and are crucial for autophagy, apoptosis, and necroptosis.

Purpose of the Study:

To investigate the role of mitochondrial network structure homeostasis in autophagy, apoptosis, and necroptosis.
To explore the significance of fragmented mitochondrial phenotype in cancer progression, prognosis, and therapeutic response.
To evaluate targeting the mitochondrial fission protein Drp1 as a potential therapeutic strategy.

Main Methods:

Review and analysis of existing literature on mitochondrial dynamics and cell death.
Examination of the link between mitochondrial morphology and cancer characteristics.
Discussion of the therapeutic potential of targeting Drp1.

Main Results:

Mitochondrial network homeostasis is critical for regulating cell death pathways.
Fragmented mitochondrial phenotype is prevalent in various cancers and correlates with tumor progression.
Drp1 emerges as a key regulator of mitochondrial fission with implications in cell death.

Conclusions:

The balance of mitochondrial fission and fusion is integral to cell fate decisions.
Targeting Drp1 presents a promising avenue for novel cancer therapeutics by modulating mitochondrial dynamics.
