Abstract

Insights

Inhibition of Fucosyltransferase4 (FUT4) activates Forkhead box O1 (FOXO1), reducing osteosarcoma cell proliferation, invasion, and migration. This suggests FUT4 inhibition is a potential therapeutic strategy for osteosarcoma by targeting the Wnt/β-catenin pathway.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Fucosyltransferase4 (FUT4) inhibition activates Forkhead box O1 (FOXO1), inducing cancer cell apoptosis.
  • The precise mechanism of FUT4 and FOXO1 in osteosarcoma remains unclear.

Purpose of the Study:

  • To investigate the biological role of the FUT4-FOXO1 interaction in osteosarcoma progression.
  • To determine if FUT4 inhibition impacts osteosarcoma cell proliferation, migration, invasion, and apoptosis.

Main Methods:

  • Utilized in vitro assays with human osteoblast and osteosarcoma cell lines.
  • Assessed FUT4 and FOXO1 expression via qRT-PCR and Western blot.
  • Evaluated osteosarcoma cell proliferation, migration, invasion, and apoptosis using CCK-8, colony, EDU, wound healing, Transwell, and TUNEL assays.
  • Investigated the Wnt/β-catenin signaling pathway and related protein markers.

Main Results:

  • Osteosarcoma cells exhibited higher FUT4 expression compared to osteoblasts.
  • FUT4 inhibition significantly suppressed osteosarcoma cell proliferation, invasion, and migration.
  • Inhibition of FUT4 led to increased osteosarcoma cell apoptosis.
  • FUT4 inhibition blocked the Wnt/β-catenin pathway by upregulating FOXO1 expression.

Conclusions:

  • Osteosarcoma cells overexpress FUT4.
  • FUT4 inhibition targets FOXO1 activation, impacting the Wnt/β-catenin pathway and reducing osteosarcoma cell viability.
  • Targeting FUT4 offers a potential therapeutic strategy for osteosarcoma treatment.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

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...

Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...

Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
