Insights

KIN17 promotes renal cell carcinoma (RCC) progression, invasion, and metastasis. Targeting the PI3K/AKT/mTOR pathway with inhibitors can reverse these effects, suggesting KIN17 as a therapeutic target for RCC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • The role of KIN17, a DNA and RNA binding protein, in renal cell carcinoma (RCC) progression and metastasis is not well understood.
  • KIN17 is implicated in the tumorigenesis of various human cancers.

Purpose of the Study:

  • To elucidate the function of KIN17 in RCC.
  • To investigate KIN17's role in cancer progression and metastasis.
  • To explore KIN17 as a potential therapeutic target in RCC.

Main Methods:

  • In vivo and in vitro studies using the PI3K/mTOR inhibitor PF-04691502.
  • Bioinformatics Analysis, Immunohistochemistry (IHC), Scratch Wound Healing Assay, Cell Viability Assay, Colony Formation Assays, EdU-647 Labeling.
  • Cell Cycle and Apoptosis Detection (flow cytometry), Western Blotting, and Animal Experiments were performed.

Main Results:

  • KIN17 promotes RCC cell proliferation, cell cycle progression, and colony formation.
  • KIN17 reduces cell apoptosis and enhances cell invasion and migration.
  • PI3K/mTOR pathway inhibition reversed KIN17's pro-tumorigenic effects in vitro and in vivo.
  • Inhibitor treatment also reversed the activation of the PI3K/AKT/mTOR signaling pathway.

Conclusions:

  • KIN17 promotes RCC progression, invasion, and metastasis.
  • KIN17 could serve as a prognostic biomarker for RCC migration and invasion.
  • Targeting KIN17, potentially via the PI3K/AKT/mTOR pathway, represents a promising therapeutic strategy for RCC.

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 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...

Facilitated Transport01:19

Facilitated Transport

The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In  facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
