Abstract

Insights

Beta-estradiol influences breast cancer (BC) progression and metastasis by altering gene expression. This study identified key genes and microRNAs involved in BC regulation by beta-estradiol.

Area of Science:

  • Molecular Biology
  • Genomics
  • Cancer Research

Background:

  • Investigates the molecular mechanisms of beta-estradiol action in MCF-7 breast cancer cells.
  • Addresses the need to understand hormone-driven breast cancer progression.

Purpose of the Study:

  • To elucidate the action mechanism of beta-estradiol in breast cancer.
  • To identify key genes and pathways regulated by beta-estradiol in MCF-7 cells.

Main Methods:

  • RNA sequencing of MCF-7 cells treated with beta-estradiol.
  • Differential gene expression analysis using NOISeq and WbeGestalt.
  • Pathway and gene ontology analysis, miRNA target prediction, and protein-protein interaction network construction.

Main Results:

  • Identified 1,835 differentially expressed genes (DEGs) in breast cancer samples.
  • Found DEGs involved in cell proliferation, hormone response, and significant pathways.
  • Identified hub genes including estrogen receptor 1 and cathepsin D (CTSD), with hsa-miR-140-3p as a target miRNA for CTSD.

Conclusions:

  • Beta-estradiol plays a significant role in breast cancer progression and metastasis.
  • Regulation of identified genes by beta-estradiol contributes to cancer development.
  • Findings provide insights into potential therapeutic targets for hormone-driven breast cancer.

Role-Based Identity01:21

Role-Based Identity

Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II  is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....

Role of Microtubules in Cell Wall Deposition01:02

Role of Microtubules in Cell Wall Deposition

Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

The Role of Actin and Myosin in Non-muscle Cells

Actin and myosin or actomyosin filaments also play a significant role in cells other than those involved in muscle contraction (which occurs within the sarcomere of muscle cells). The mechanism of non-muscle cell contractile bundles was first observed in Dictyostelium and Acanthamoeba. In non-muscle cells, two bundles are commonly found: stress fibers and actomyosin adherence belts. These contractile bundles are smaller and less organized than the ones found in muscle cells. They  are held...

Role of Septins01:02

Role of Septins

Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...
