Summary
Loss of BAF250a protein expression in breast cancer correlates with advanced disease characteristics. This protein
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Breast cancer remains a leading cause of cancer-related mortality worldwide.
- Understanding molecular markers associated with breast cancer progression is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate the expression of BAF250a protein in breast cancer tissues.
- To analyze the association between BAF250a expression and clinicopathological features.
- To evaluate the prognostic significance of BAF250a in breast cancer patients.
Main Methods:
- Western blot analysis and immunohistochemical staining were used to detect BAF250a protein expression in 496 breast cancer specimens.
- Statistical analyses, including t-tests, correlation analyses, and Cox regression, were employed to assess relationships.
Main Results:
- BAF250a protein expression was significantly lower in breast cancer tissues compared to normal tissues.
- Loss of BAF250a expression correlated with higher histological grade, lymph node metastasis, advanced TNM stage, and altered ER, PR, c-erbB-2, and p53 status.
- Patients with BAF250a expression had significantly better disease-specific survival.
Conclusions:
- BAF250a protein expression loss is associated with aggressive clinicopathological features in breast cancer.
- BAF250a deletion is an independent prognostic factor for poor survival in breast cancer.
- BAF250a represents a potential therapeutic target for breast cancer treatment.

Cancer-Critical Genes II: Tumor Suppressor Genes
8.3K
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.

The Retinoblastoma Gene
3.7K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Abnormal Proliferation
4.0K
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...

mTOR Signaling and Cancer Progression
3.6K
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.

lncRNA - Long Non-coding RNAs
7.5K
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...
