Insights

This review explores how γ-secretase subunits contribute to breast cancer (BC) progression and chemoresistance. Targeting these subunits offers potential new therapies for overcoming treatment resistance in BC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Breast cancer (BC) is a leading cause of cancer death in women.
  • Current treatments like chemotherapy face challenges due to emerging drug resistance.
  • The Notch signaling pathway is implicated in BC development and progression.

Purpose of the Study:

  • To review the structure-function relationships and interactions of key γ-secretase subunits.
  • To elucidate the role of γ-secretase subunits in breast cancer pathogenesis.
  • To discuss the potential of γ-secretase inhibitors for overcoming BC chemoresistance.

Main Methods:

  • Literature review focusing on γ-secretase subunits (PSEN1, PSEN2, PEN-2, NCSTN, APH-1).
  • Analysis of preclinical studies and clinical trials.
  • Examination of structure-function relationships and subunit interactions.

Main Results:

  • Detailed elucidation of γ-secretase subunit roles in BC progression.
  • Emphasis on the link between γ-secretase complex and BC pathogenesis.
  • Discussion of preclinical and clinical data regarding γ-secretase and BC.

Conclusions:

  • γ-secretase complex plays a significant role in breast cancer.
  • Targeting γ-secretase subunits presents a promising therapeutic strategy for chemoresistant breast cancer.
  • Further research into γ-secretase inhibitors is warranted for BC treatment.

Tumor Progression02:07

Tumor Progression

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...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

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...

Overview of Secretory Vesicles01:33

Overview of Secretory Vesicles

Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...
