Abstract

Insights

Methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) is upregulated in hepatocellular carcinoma (HCC), driving proliferation and reducing drug sensitivity. Targeting MTHFD2 may improve HCC therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) is implicated in cancer progression.
  • Its specific role in hepatocellular carcinoma (HCC) cell proliferation and chemosensitivity is not well understood.

Purpose of the Study:

  • To investigate the role of MTHFD2 in HCC cell proliferation and chemosensitivity.
  • To explore MTHFD2 as a potential therapeutic target for HCC.

Main Methods:

  • Immunohistochemistry and qRT-PCR to assess MTHFD2 expression in 95 HCC tissues.
  • Bioinformatics analyses (GSEA, KEGG) to predict involved signaling pathways.
  • MTHFD2 knockdown experiments using CCK-8 and EdU assays to evaluate anti-tumor effects and drug sensitivity.

Main Results:

  • MTHFD2 was frequently upregulated in HCC tissues, correlating with poor prognosis when co-expressed with Ki67.
  • MTHFD2 knockdown inhibited HCC cell proliferation and enhanced sensitivity to sorafenib and lenvatinib.
  • The PI3K/AKT pathway was identified as a key mediator of MTHFD2's effects on proliferation and chemosensitivity.

Conclusions:

  • MTHFD2 significantly influences HCC cell proliferation and chemosensitivity.
  • MTHFD2 represents a promising novel pharmacological target for enhancing hepatocellular carcinoma treatment strategies.

Abnormal Proliferation02:23

Abnormal Proliferation

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...

mTOR Signaling and Cancer Progression03:03

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...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

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...

Interactions Between Signaling Pathways01:19

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...
