Summary
Cyclin-dependent kinase-like 3 (CDKL3) promotes osteosarcoma progression by activating the Akt pathway. High CDKL3 expression correlates with poorer patient survival, identifying it as a potential biomarker and therapeutic target for this bone cancer.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Osteosarcoma (OS) is a primary bone cancer characterized by frequent metastasis and recurrence.
- The Akt/PKB signaling pathway is implicated in tumorigenesis, but the role of CDKL3 in OS is unclear.
Purpose of the Study:
- To investigate the role of cyclin-dependent kinase-like 3 (CDKL3) in osteosarcoma (OS) progression.
- To determine if CDKL3 expression correlates with patient survival and Akt pathway activation.
Main Methods:
- Analysis of CDKL3 expression in human OS specimens.
- In vitro and in vivo studies to assess CDKL3's functional role in OS.
- Investigation of CDKL3's effect on Akt activation and downstream signaling.
Main Results:
- CDKL3 is highly expressed in OS specimens.
- CDKL3 promotes OS progression by regulating Akt activation, cell growth, and autophagy.
- Increased CDKL3 expression is associated with activated Akt and shorter patient survival (P = 0.003).
Conclusions:
- CDKL3 is a critical regulator of OS progression via Akt activation.
- CDKL3 serves as a prognostic biomarker for OS.
- Targeting CDKL3 offers a potential therapeutic strategy for Akt-hyperactivated OS in precision medicine.

01:22PI3K/mTOR/AKT Signaling Pathway
5.1K
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...

03:03mTOR Signaling and Cancer Progression
4.5K
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.

02:34Inhibition of Cdk Activity
5.5K
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...

02:15M-Cdk Drives Transition Into Mitosis
6.2K
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

01:07MAPK Signaling Cascades
7.7K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

02:23Abnormal Proliferation
5.0K
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...
