Summary

This summary is machine-generated.

Fibroblast growth factor binding protein 1 (FGFBP1) promotes triple-negative breast cancer (TNBC) growth and spread. Targeting FGFBP1 may offer a new therapeutic strategy for TNBC by inhibiting the KLK10-AKT pathway.

Area Of Science

  • Oncology
  • Molecular Biology

Background

  • Triple-negative breast cancer (TNBC) is aggressive and lacks targeted therapies.
  • The fibroblast growth factor (FGF) pathway is implicated in TNBC progression.
  • FGFBP1 releases FGFs, but its role in TNBC is unclear.

Purpose Of The Study

  • To investigate the role of FGFBP1 in TNBC progression.
  • To elucidate the molecular mechanism by which FGFBP1 affects TNBC.

Main Methods

  • In vitro and in vivo experiments using TNBC cell lines.
  • Analysis of FGFBP1, KLK10, and AKT pathway expression.
  • Gene knockdown and pathway inhibition studies.

Main Results

  • FGFBP1 overexpression enhanced TNBC cell proliferation, migration, and invasion.
  • FGFBP1 upregulated KLK10, activating the AKT pathway.
  • Knocking down FGFBP1 or KLK10, or inhibiting AKT, reversed these effects.

Conclusions

  • FGFBP1 promotes TNBC progression via the KLK10-AKT axis.
  • Targeting FGFBP1 represents a potential therapeutic strategy for TNBC.

PI3K/mTOR/AKT Signaling Pathway 01:22

3.3K

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 03:03

3.6K

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.

Tumor Progression 02:07

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...

Mitogens and the Cell Cycle 02:38

6.3K

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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...

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Three of the best-understood negative regulators are p53, p21, and retinoblastoma protein (Rb). The regulatory roles of each of these proteins were discovered after faulty copies were found in cells with uncontrolled replication (i.e.,...
