Abstract

Insights

High-mobility group box 1 (HMGB1) protein fuels cancer growth, spread, and immune evasion. Targeting HMGB1 presents a promising therapeutic strategy for combating various cancers, particularly metastasis.

Area of Science:

  • Oncology
  • Immunology

Background:

  • High-mobility group box 1 (HMGB1) is implicated in cancer development, progression, and metastasis.
  • HMGB1 promotes cancer cell activation, tumor angiogenesis, and suppresses anti-cancer immunity.

Purpose of the Study:

  • To review the biological characteristics and multifaceted roles of HMGB1 in cancer.
  • To explore novel techniques for HMGB1 inhibition in cancer therapy.

Main Methods:

  • Review of existing literature on HMGB1's biological functions and its interactions within the tumor microenvironment.
  • Analysis of HMGB1's dual role in promoting cancer cell aggressiveness and inhibiting anti-cancer immune responses.
  • Overview of emerging therapeutic strategies targeting HMGB1.

Main Results:

  • HMGB1, a non-histone protein, acts as a secretory protein and DNA chaperone, binding to receptors on cancer and immune cells.
  • HMGB1 enhances cancer cell proliferation, motility, invasion, and survival.
  • HMGB1 suppresses anti-cancer immunity by inducing apoptosis in immune cells and impairing macrophage and dendritic cell function.

Conclusions:

  • Targeting HMGB1 is a potential therapeutic strategy against cancer development, progression, and metastasis.
  • Various HMGB1-targeting techniques are under investigation.
  • Urgent technical advancements are needed for the clinical application of HMGB1 targeting in human diseases.

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 specific...
Histone Variants at the Centromere02:30

Histone Variants at the Centromere

Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3 variants are also...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
