Elf5 - breast cancer's little helper.
Breast Cancer Research : BCR
|March 29, 2013
Summary
E74-like factor 5 (Elf5) is a marker for aggressive basal breast cancers and anti-oestrogen resistance. Targeting Elf5 may offer new treatment strategies for these challenging cancers.
Area of Science:
- Molecular biology
- Cancer research
- Endocrinology
Background:
- Transcription factors regulate mammary gland development and are linked to breast cancer subtypes.
- E74-like factor 5 (Elf5) is implicated in oestrogen receptor status and breast cancer aggressiveness.
Purpose of the Study:
- To investigate the role of Elf5 in mammary gland lineage commitment and breast cancer subtypes.
- To explore Elf5 as a potential therapeutic target for basal breast cancers.
Main Methods:
- Analysis of Elf5 expression in relation to oestrogen receptor status.
- Correlation of high Elf5 expression with aggressive basal cancers and anti-oestrogen resistance.
- Manipulation of Elf5 transcript levels to observe effects on luminal and basal subtype molecular profiles.
Main Results:
- Elf5 identified as a marker for oestrogen receptor status.
- High Elf5 expression is associated with more aggressive basal breast cancers.
- High Elf5 expression correlates with resistance to anti-oestrogen therapies.
- Altering Elf5 levels impacts the molecular characteristics of luminal and basal breast cancer subtypes.
Conclusions:
- Elf5 plays a significant role in mammary gland lineage and breast cancer subtypes.
- Targeting Elf5 presents a potential novel therapeutic strategy for basal breast cancer treatment.

02:18Cancer
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.
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

02:53Adaptive 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.
