Insights

Uncontrolled PIM and Akt kinases drive cancer by regulating cell survival pathways. Targeting these kinases may enhance cancer therapies by disrupting overlapping survival signals crucial for tumor growth and spread.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Human cancer initiation and progression are often driven by the overactivation of pro-survival kinases.
  • PIM and Akt are serine/threonine kinases frequently amplified in cancer, regulating cell cycle, metabolism, proliferation, and survival.
  • Cross-talk between PIM and Akt kinases suggests overlapping signaling pathways critical for tumorigenesis and metastasis.

Purpose of the Study:

  • To review the regulation of PIM kinases.
  • To elucidate the role of PIM kinases in tumorigenesis.
  • To examine the biological impact of PIM and Akt signaling pathway interaction on cancer therapy efficacy.

Main Methods:

  • Literature review focusing on PIM kinase regulation, function, and interaction with Akt signaling.
  • Analysis of existing evidence on the role of PIM and Akt in cancer initiation, progression, and metastasis.
  • Discussion of the therapeutic potential of PIM kinase inhibition in conjunction with standard and targeted cancer therapies.

Main Results:

  • PIM and Akt kinases are key regulators of cancer cell survival and proliferation.
  • The interaction between PIM and Akt signaling pathways contributes to cancer initiation, progression, and metastatic spread.
  • Pharmacological inhibition of PIM kinases shows potential to modulate the efficacy of existing cancer treatments.

Conclusions:

  • PIM kinases are critical regulators of tumorigenesis and represent a promising target for anticancer therapy.
  • Understanding the interplay between PIM and Akt signaling is crucial for developing effective combination therapies.
  • Targeting PIM kinases could enhance the effectiveness of current cancer treatments, offering new therapeutic strategies.

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 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.

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...

Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...
