Insights

The AKT2 oncogene drives cancer progression, invasion, and metastasis. MicroRNAs (miRNAs) regulate AKT2, offering potential as diagnostic and therapeutic cancer markers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • The AKT signaling pathway, particularly its AKT2 isoform, is frequently hyperactivated in human cancers.
  • AKT2 hyperactivation promotes tumor growth, angiogenesis, metastasis, and chemoresistance.
  • AKT2 amplification and overexpression are observed across various cancer types.

Purpose of the Study:

  • To review the role of AKT2 activation in tumor progression across diverse cancers.
  • To explore the involvement of microRNAs (miRNAs) in regulating AKT2 expression in cancer.
  • To identify AKT2-related miRNAs as potential cancer biomarkers.

Main Methods:

  • In-depth literature review of studies on AKT2 and cancer.
  • Analysis of research on miRNA regulation of AKT2.
  • Synthesis of findings on AKT2's role in cancer hallmarks.

Main Results:

  • AKT2 is critically involved in cancer cell invasion, metastasis, and survival.
  • Various miRNAs have been identified that modulate AKT2 expression.
  • These AKT2-regulating miRNAs show potential as diagnostic, prognostic, and therapeutic targets.

Conclusions:

  • AKT2 hyperactivation is a key driver of malignant progression in many cancers.
  • miRNAs represent a significant regulatory mechanism for AKT2 in tumorigenesis.
  • Targeting AKT2-related miRNAs may offer novel strategies for cancer management.

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
