Insights

Annexin A4 (ANXA4) is linked to tumor development and invasion across many cancers. Reducing ANXA4 may improve chemotherapy effectiveness and offers a potential therapeutic target for cancer treatment.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • Annexin A4 (ANXA4) is a calcium and phospholipid-binding protein.
  • ANXA4 plays roles in membrane dynamics, cell growth, apoptosis, and tumor progression.

Purpose of the Study:

  • To investigate the role of ANXA4 in various epithelial cancers.
  • To evaluate ANXA4 as a potential biomarker and therapeutic target.

Main Methods:

  • Analysis of ANXA4 expression in clinical epithelial tumors.
  • Investigating the effects of ANXA4 knockdown on cancer cell migration and drug resistance.

Main Results:

  • ANXA4 overexpression is found in lung, gastric, colorectal, pancreatic, breast, ovarian, and other cancers.
  • ANXA4 knockdown reduced migration in ovarian and breast cancer cells.
  • ANXA4 knockdown increased sensitivity to platinum-based chemotherapy in ovarian cancer and mesothelioma cells.

Conclusions:

  • ANXA4 is implicated in tumor development, invasion, and chemoresistance.
  • ANXA4 may serve as a prognostic indicator and a therapeutic target for cancer patients.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Selectins01:25

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

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...
