Summary
L1-cell adhesion molecule (L1-CAM) is found in various cancers. Targeting L1-CAM with antibodies inhibits cancer cell growth and reduces tumor burden, making it a promising therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Cell Biology
Background:
- L1-cell adhesion molecule (L1-CAM) is an immunoglobulin superfamily cell adhesion receptor.
- Initially known for neural functions, L1-CAM is now recognized in various human cancers.
Purpose of the Study:
- Review L1-CAM prevalence in human cancers.
- Investigate L1-CAM's role in tumorigenesis.
- Explore L1-CAM antibody-based cancer therapies.
Main Methods:
- Identified L1-CAM as a Wnt/beta-catenin-TCF pathway target in colon cancer.
- Detected L1-CAM at the invasive front of colon and ovarian cancers.
- Assessed L1-CAM's impact on tumorigenesis and metastasis in colon cancer models.
Main Results:
- L1-CAM expression enhanced tumorigenesis and metastasis in colon cancer.
- Antibodies against L1-CAM inhibited proliferation of diverse cancer cells in vitro.
- L1-CAM antibody treatment reduced tumor burden in vivo.
Conclusions:
- L1-CAM is expressed at the invasive front of colon and ovarian cancers.
- L1-CAM promotes cancer progression and metastasis.
- L1-CAM is a viable therapeutic target due to its cell surface presence and restricted normal tissue distribution.

lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
