Summary
Homeobox protein MEIS2 acts as a tumor suppressor in breast cancer. Lower MEIS2 levels correlate with advanced stages, while targeting MEIS2 may offer new breast cancer therapies.
Area of Science:
- Oncology
- Molecular Biology
- Gene Regulation
Background:
- Breast cancer (BC) is a leading female cancer.
- Homeobox protein MEIS2 regulates cellular processes, but its role in BC is unknown.
Purpose of the Study:
- Investigate MEIS2's role in breast cancer.
- Determine MEIS2's association with BC stages and grades.
- Elucidate MEIS2's mechanism in BC cell growth and tumor development.
Main Methods:
- Analysis of human BC cell lines, clinical samples, and xenograft models.
- MEIS2 knockdown and overexpression experiments.
- Screening of MEIS2 target genes, including IL10.
- Assessment of myeloid cell infiltration.
Main Results:
- MEIS2 functions as a tumor suppressor in breast cancer.
- MEIS2 expression inversely correlates with BC stage and grade.
- MEIS2 knockdown increases IL10 expression and proliferation; MEIS2 overexpression suppresses them.
- MEIS2's suppressive role involves IL10 regulation and myeloid cell infiltration.
Conclusions:
- MEIS2 suppresses breast cancer progression by downregulating IL10 and promoting myeloid cell infiltration.
- Targeting MEIS2 presents a potential therapeutic strategy for breast cancer.

01:22MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

02:23Abnormal Proliferation
4.5K
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...

01:15Receptor Downregulation in MVBs
2.1K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

7.4K
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.

4.8K
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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:43Mouse Models of Cancer Study
5.5K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
