Summary
This summary is machine-generated.Serine incorporator 2 (SERINC2) drives cervical cancer growth by altering serine metabolism and depleting immune cells. Targeting SERINC2 may offer a new therapeutic strategy for cervical cancer.
Area Of Science
- Oncology
- Immunology
- Metabolic Research
Background
- Cervical cancer is a leading gynecological malignancy.
- Tumor immune metabolism reprogramming is a promising therapeutic target.
- The role of serine metabolism in cervical cancer immunity is not fully understood.
Purpose Of The Study
- To investigate the role of serine incorporator 2 (SERINC2) in cervical cancer.
- To elucidate the impact of SERINC2 on tumor immune metabolism and T cell function.
Main Methods
- Functional assays (in vivo and in vitro) were performed.
- SERINC2 expression and its correlation with clinical outcomes were analyzed.
- Immune infiltration and serine metabolism were assessed.
- Mechanistic studies explored the competition for serine between cancer and immune cells.
Main Results
- SERINC2 is highly expressed in cervical cancer and linked to poor outcomes.
- SERINC2 promotes tumor growth and serine dependency.
- SERINC2 knockdown reduces intracellular serine and alters lipid metabolism.
- SERINC2 negatively impacts CD8+ T cell infiltration and function, causing T cell exhaustion by competing for serine.
Conclusions
- SERINC2 plays a pro-tumoral role in cervical cancer by remodeling serine metabolism.
- SERINC2 contributes to an immunosuppressive tumor immune microenvironment (TIME).
- Targeting SERINC2 presents a potential therapeutic strategy for cervical cancer.

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...
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...
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
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...
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.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
