Insights

Histone deacetylase 6 (HDAC6) regulates cancer cell growth through non-histone substrates. Selective HDAC6 inhibitors are crucial for developing targeted cancer therapies with fewer side effects.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • HDAC6 is a cytosolic protein regulating cell growth via non-histone substrates like α-tubulin, cortactin, HSP90, PD-1, and PD-L1.
  • These substrates are critical in cancer proliferation, invasion, immune escape, and angiogenesis.
  • Current HDAC inhibitors are non-selective pan-inhibitors, leading to significant side effects.

Purpose of the Study:

  • To review the role of HDAC6 in cancer.
  • To discuss recent strategies for designing selective HDAC6 inhibitors for cancer therapy.

Main Methods:

  • Literature review of studies on HDAC6 and cancer.
  • Analysis of design strategies for HDAC6 inhibitors.

Main Results:

  • HDAC6 plays a significant role in various cancer hallmarks.
  • The development of selective HDAC6 inhibitors is a promising therapeutic strategy.
  • Recent research focuses on novel molecular designs for targeted inhibition.

Conclusions:

  • HDAC6 is a key therapeutic target in cancer.
  • Selective HDAC6 inhibition offers a promising avenue for improved cancer treatment with reduced toxicity.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Structure-Activity Relationships and Drug Design

Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
