Patients with multiple endocrine neoplasia type 1 (MEN1) have higher breast cancer risk. This review explores menin

Area Of Science

  • Oncology
  • Molecular Biology
  • Genetics

Background

  • Multiple Endocrine Neoplasia type 1 (MEN1) is linked to increased breast carcinogenesis risk.
  • The MEN1 gene product, menin, plays a crucial role in breast cancer signaling pathways.

Purpose Of The Study

  • To review menin's molecular mechanisms in breast cancer.
  • To elucidate menin's role in gene transcription and signaling.
  • To guide the development of novel menin-targeted breast cancer therapies.

Main Methods

  • Literature review of menin's interactions and functions in breast cancer.
  • Analysis of menin's modulation of gene transcription and DNA repair.
  • Examination of menin's role in apoptosis induction.

Main Results

  • Menin interacts with multiple proteins (MLL, EZH2, JunD, NF-κB, PPARγ, VDR, Smad3, β-catenin, ERα) to inhibit cell proliferation.
  • Menin enhances BRCA1-mediated DNA repair via FANCD2 interaction.
  • Ectopic menin expression induces apoptosis.

Conclusions

  • Menin is a key regulator in breast cancer development and progression.
  • Understanding menin's pathways is essential for targeted breast cancer drug development.
  • Further research on menin inhibitors for breast cancer treatment is warranted.

Targeted Cancer Therapies 02:57

7.5K

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Mitogens and the Cell Cycle 02:38

6.4K

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...

Canonical Wnt Signaling Pathway 02:54

8.7K

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Non-Canonical Wnt Signaling Pathways 01:41

7.3K

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

PI3K/mTOR/AKT Signaling Pathway 01:22

3.5K

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...

Interactions Between Signaling Pathways 01:19

6.3K

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...
