Insights

The phosphatidylinositol-3-kinase (PI3K) pathway is crucial for cell functions but often dysregulated in cancers like lymphoma. This review examines PI3K pathway inhibitors for treating these malignancies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The phosphatidylinositol-3-kinase (PI3K) pathway regulates vital cellular processes such as metabolism, proliferation, and survival.
  • Aberrations in the PI3K pathway, including mutations and amplifications, are common in various cancers.
  • Constitutive PI3K pathway activation confers a survival advantage and promotes resistance to therapy in malignancies like lymphomas.

Purpose of the Study:

  • To review the current status of phosphatidylinositol-3-kinase (PI3K) pathway inhibitors in clinical development.
  • To focus on the therapeutic potential of these inhibitors specifically for treating Hodgkin and non-Hodgkin lymphomas.

Main Methods:

  • Literature review of clinical trials and preclinical studies.
  • Analysis of data on PI3K pathway aberrations in lymphoid malignancies.
  • Evaluation of the efficacy and safety of various PI3K inhibitors in lymphoma models.

Main Results:

  • The PI3K pathway is frequently activated in Hodgkin and non-Hodgkin lymphomas, contributing to cancer progression.
  • Numerous PI3K inhibitors targeting different pathway components are in various stages of clinical trials.
  • These inhibitors show promise in preclinical models and early-phase clinical studies for lymphoma treatment.

Conclusions:

  • Targeting the PI3K pathway represents a promising therapeutic strategy for lymphomas.
  • Further clinical development of PI3K inhibitors is warranted to overcome treatment resistance and improve patient outcomes.
  • Understanding PI3K pathway dysregulation is key to developing effective lymphoma therapies.

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...

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.

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...

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...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
