What are Heat Shock Proteins (HSPs)?

Heat shock proteins (HSPs) are a class of highly conserved proteins that play a critical role in protecting cells from stress, maintaining cellular homeostasis, and ensuring proper protein folding. These proteins are often referred to as "molecular chaperones" because they assist in the proper folding, stabilization, and trafficking of other proteins. HSPs are upregulated under stress conditions, such as heat shock, oxidative stress, or other environmental challenges, to prevent the accumulation of misfolded or damaged proteins.

There are several types of HSPs, categorized by their molecular weight, including HSP60, HSP70, HSP90, and HSP100. Among these, HSP90 is one of the most studied and has been found to play a central role in regulating cellular processes beyond stress response. HSP90 interacts with a wide range of client proteins, many of which are involved in essential processes such as signal transduction, cell growth, and survival.

The Role of HSP90 in Cellular Signaling

HSP90 is involved in regulating a variety of cellular processes, particularly those related to signal transduction, protein folding, and the stabilization of key regulatory proteins. Here are some of the core functions of HSP90 in cellular signaling:

1. Protein Folding and Stability

As a molecular chaperone, HSP90 is primarily involved in ensuring that newly synthesized proteins fold into their correct three-dimensional shapes. Proper protein folding is crucial for cellular function, and any failure in this process can lead to the accumulation of misfolded proteins, which may be toxic to cells. HSP90 works alongside other chaperones, such as HSP70, to assist in folding nascent proteins and preventing protein aggregation.

In addition to folding newly synthesized proteins, HSP90 also helps stabilize and refold damaged or misfolded proteins under stress conditions. This process is particularly important in maintaining the functionality of essential cellular proteins, including those involved in the cell cycle, signal transduction, and metabolism.

2. Regulation of Signaling Pathways

HSP90 is involved in the regulation of several critical signaling pathways by interacting with key client proteins, many of which are involved in cell growth, survival, and differentiation. These client proteins include hormone receptors, kinases, and transcription factors. By stabilizing these client proteins, HSP90 ensures that they are able to function properly and regulate essential cellular processes.

For example, HSP90 is involved in the stabilization of several receptor tyrosine kinases (RTKs) and growth factors that play key roles in cellular signaling. It also interacts with steroid hormone receptors (such as the estrogen receptor) and transcription factors that regulate gene expression.

3. Stress Response

One of the primary functions of HSP90 is to assist in the cellular stress response. Under conditions of stress, such as heat shock or oxidative damage, the levels of HSPs are significantly upregulated to help protect cells from damage. In particular, HSP90 aids in the refolding of damaged proteins and facilitates the degradation of irreparably misfolded proteins, thus preventing toxic aggregation.

By stabilizing client proteins involved in the stress response, HSP90 plays a critical role in protecting cells from damage and ensuring that key cellular processes, such as cell survival and recovery, continue to function during stressful conditions.

4. Cancer and Tumorigenesis

HSP90 has become a focus of cancer research because of its involvement in regulating proteins that are critical for cancer cell survival and growth. Many of the client proteins that interact with HSP90 are involved in tumorigenesis, including mutated or overexpressed oncogenes, kinases, and growth factor receptors.

For example, HSP90 stabilizes several key oncogenic proteins, including mutant forms of the epidermal growth factor receptor (EGFR), which is commonly overexpressed in cancers such as lung cancer and breast cancer. By maintaining the stability of these proteins, HSP90 helps promote cancer cell survival, proliferation, and resistance to apoptosis (programmed cell death). As a result, HSP90 has become a promising target for cancer therapies.

Therapeutic Potential of Targeting HSP90 (Including HSP90 Inhibitors)

Due to its central role in regulating critical cellular processes, HSP90 has emerged as an attractive target for therapeutic interventions, particularly in cancer treatment. Targeting HSP90 with small molecule inhibitors has shown promise in disrupting the stability of key client proteins involved in cancer cell growth and survival.

1. Cancer Therapy: Targeting HSP90

HSP90 inhibitors are being explored as a potential treatment for various types of cancer, including breast cancer, lung cancer, prostate cancer, and glioblastoma. These inhibitors work by binding to the ATP-binding pocket of HSP90, preventing the protein from undergoing conformational changes necessary for its chaperone activity. As a result, client proteins that rely on HSP90 for stability become destabilized and are degraded by the cell.

Several HSP90 inhibitors, such as 17-AAG (tanespimycin) and NVP-AUY922, have shown efficacy in preclinical and early clinical studies. These inhibitors disrupt the stability of key oncogenic proteins, leading to cancer cell death and tumor regression. HSP90 inhibitors are often used in combination with other cancer therapies, such as chemotherapy or targeted therapies, to enhance their effectiveness.

2. Neurodegenerative Diseases: Modulating HSP90 Activity

In addition to cancer, HSP90 has been implicated in several neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. In these conditions, the accumulation of misfolded proteins leads to cellular dysfunction and neurodegeneration. HSP90’s role in protein folding and stability makes it a potential therapeutic target for modulating the accumulation of toxic proteins in neurodegenerative diseases.

By enhancing HSP90 activity or using HSP90 modulators, researchers hope to promote the clearance of misfolded proteins and prevent neuronal damage in conditions like Alzheimer’s disease. Some studies suggest that HSP90 inhibitors may be able to reduce the accumulation of amyloid-beta plaques in Alzheimer's disease, providing a potential avenue for treatment.

3. Infectious Diseases and Autoimmune Disorders

HSP90 is also involved in regulating the immune response and the function of immune cells. By targeting HSP90, researchers are exploring potential therapies for autoimmune diseases and infectious diseases. In autoimmune disorders like rheumatoid arthritis, targeting HSP90 could help modulate the immune response and reduce inflammation. Similarly, HSP90 inhibitors may help target the stability of proteins involved in the replication of viruses, offering a potential strategy for combating viral infections.
