Summary
MYH9 is upregulated in cervical squamous cell carcinoma (SCC), promoting cancer cell proliferation and migration. Targeting MYH9 may offer a new biomarker for SCC treatment.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Cervical cancer (CC) is a significant global health issue, ranking as the third most common cancer in women.
- Squamous cell carcinoma (SCC) accounts for approximately 70% of CC cases, yet its underlying molecular mechanisms remain incompletely understood.
Purpose of the Study:
- To investigate the role of MYH9 in the molecular mechanisms of cervical squamous cell carcinoma (SCC).
- To determine if MYH9 could serve as a potential biomarker for targeted SCC treatment.
Main Methods:
- Quantitative real-time PCR (RT-qPCR) and Western blotting were used to assess MYH9 expression in SCC tissues.
- In vitro assays, including MTT, EdU, Transwell, and Boyden, were employed to evaluate the impact of MYH9 on SCC cell proliferation, migration, and invasion.
- Epithelial-mesenchymal transition (EMT) markers and cell-cycle related factors were analyzed following MYH9 knockdown.
Main Results:
- MYH9 mRNA and protein levels were significantly elevated in SCC tissues compared to adjacent normal tissues.
- MYH9 knockdown inhibited proliferation in both Siha and C-33A SCC cell lines.
- MYH9 knockdown suppressed migration and invasion in Siha cells, linked to the inhibition of EMT and downstream factors like c-Jun and cyclin-D1.
Conclusions:
- MYH9 is upregulated in cervical squamous cell carcinoma and promotes SCC cell proliferation, migration, and invasion.
- MYH9 facilitates SCC progression by regulating epithelial-mesenchymal transition (EMT) signaling pathways.
- MYH9 presents potential as a diagnostic biomarker and therapeutic target for cervical cancer.

02:23Abnormal Proliferation
5.4K
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...

01:06Induced Pluripotent Stem Cells
6.3K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

7.9K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

4.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

55.8K
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.
