Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

6.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.9K
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.
The mTOR pathway or the...

Abnormal Proliferation02:23

Abnormal Proliferation

5.3K
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...

Cancer-Critical Genes I: Proto-oncogenes

11.5K
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.
Such genes that act...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

5.7K
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).
Somatic...

Tumor Progression02:07

Tumor Progression

7.5K
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...

Summary

Neuro-oncological ventral antigen 1 (NOVA1) is upregulated in osteosarcoma, promoting tumor cell viability and invasion. Suppressing NOVA1 inhibits osteosarcoma progression, indicating its oncogenic role in this bone cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Osteosarcoma is a prevalent bone tumor in adolescents and young adults.
  • Neuro-oncological ventral antigen 1 (NOVA1) is a neuron-specific RNA-binding protein implicated in various cancers.
  • The role of NOVA1 in osteosarcoma development requires further investigation.

Purpose of the Study:

  • To investigate the expression and function of NOVA1 in osteosarcoma.
  • To determine if NOVA1 acts as an oncogene or tumor suppressor in osteosarcoma.

  • Quantitative analysis of NOVA1 expression in osteosarcoma cell lines and patient tissues.
  • In vitro functional assays (cell viability, colony formation, invasion) following NOVA1 overexpression and knockdown.

Main Results:

  • NOVA1 expression is significantly upregulated in osteosarcoma tissues and cell lines compared to adjacent normal tissues.
  • Overexpression of NOVA1 enhances osteosarcoma cell viability, colony formation, and invasion.
  • Knockdown of NOVA1 inhibits osteosarcoma cell viability, colony formation, and invasion.

Conclusions:

  • NOVA1 functions as an oncogene in osteosarcoma.
  • NOVA1 upregulation promotes key malignant behaviors in osteosarcoma.
  • NOVA1 represents a potential therapeutic target for osteosarcoma.
