Summary
The unfolded protein response (UPR) is vital for glucose balance, but chronic stress impairs insulin production and promotes diabetes. Understanding UPR
Area of Science:
- Endocrinology
- Metabolic Diseases
- Cellular Biology
Background:
- Glucose homeostasis is critical for metabolic health; disruptions lead to type 2 diabetes.
- The unfolded protein response (UPR) is an endoplasmic reticulum stress mechanism.
- Chronic endoplasmic reticulum stress and UPR dysfunction are implicated in diabetes development.
Purpose of the Study:
- To review the role of the UPR in glucose homeostasis and diabetes.
- To understand how UPR dysregulation contributes to insulin resistance and β-cell dysfunction.
- To identify UPR-related therapeutic targets for diabetes.
Main Methods:
- Review of current literature on UPR and glucose metabolism.
- Analysis of UPR's impact on pancreatic β-cells and hepatocytes.
- Examination of molecular mechanisms linking UPR to diabetes pathogenesis.
Main Results:
- In pancreatic β-cells, UPR aids insulin secretion but chronic stress causes apoptosis and reduced insulin.
- In hepatocytes, UPR regulates glucose/lipid homeostasis; chronic stress leads to gluconeogenesis and steatosis.
- UPR's adaptive and maladaptive roles are key to understanding diabetes progression.
Conclusions:
- Elucidating UPR's complex role in glucose metabolism is crucial for novel diabetes therapies.
- Targeting UPR pathways may offer new therapeutic strategies for managing diabetes mellitus.

01:17Role of ER in the Secretory Pathway
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

01:02Glucose Homeostasis: Regulation of Blood Glucose
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

01:37The Unfolded Protein Response
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
