Insights

Beta-actin (ACTB), once a standard reference gene, is now recognized as a key player in various cancers. Its abnormal expression is linked to tumor invasiveness and metastasis, necessitating further research.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Beta-actin (ACTB) is traditionally used as a housekeeping reference gene in cancer research.
  • Emerging evidence links ACTB dysregulation to numerous cancer types, including liver, lung, and breast cancers.
  • ACTB is frequently upregulated in tumor cells and tissues.

Purpose of the Study:

  • To review the multifaceted roles of beta-actin (ACTB) in tumorigenesis.
  • To explore the mechanisms underlying ACTB dysregulation in various cancers.
  • To integrate current knowledge and suggest future research directions for ACTB in oncology.

Main Methods:

  • Literature review of studies investigating beta-actin (ACTB) expression and function in cancer.
  • Analysis of data on ACTB deregulation across different tumor types.
  • Synthesis of findings related to ACTB's impact on cancer cell behavior.

Main Results:

  • Beta-actin (ACTB) is abnormally expressed and frequently upregulated in a wide spectrum of human cancers.
  • Altered ACTB expression and polymerization impact the actin cytoskeleton, affecting cancer cell invasiveness and metastasis.
  • Specific mechanisms driving ACTB dysregulation in tumors are being elucidated.

Conclusions:

  • Beta-actin (ACTB) is not merely a housekeeping gene but an active contributor to cancer progression.
  • Understanding ACTB's role in cytoskeletal dynamics is crucial for cancer treatment strategies.
  • Further investigation into ACTB mechanisms is warranted to explore its therapeutic potential.

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Allosteric Proteins-ATCase

Binding sites linkages can regulate a protein's function.  For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to  N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
