Summary
RNA-binding motif 22 (RBM22) suppresses colon cancer by inducing apoptosis and reducing cell proliferation. RBM22 regulates the c-Myc pathway, impacting cancer cell growth and survival.
Area of Science:
- Molecular Biology
- Cancer Research
- Gene Regulation
Background:
- RNA-binding motif 22 (RBM22) is an RNA-binding protein with known roles in gene regulation.
- RBM22 influences glioblastoma and breast cancer cell viability and proliferation.
- The function of RBM22 in colon cancer and its underlying tumor-suppressive mechanisms are not well understood.
Purpose of the Study:
- To investigate the role of RBM22 in colon cancer.
- To elucidate the molecular mechanisms by which RBM22 exerts its tumor-suppressive effects.
- To determine the relationship between RBM22 and c-Myc in colon cancer.
Main Methods:
- RBM22 expression analysis in colon cancer cells.
- Assessment of apoptosis and cell viability upon RBM22 modulation.
- Investigation of c-Myc expression and stability following RBM22 knockdown.
Main Results:
- RBM22 induces apoptosis and suppresses colon cancer cell viability and proliferation.
- RBM22 modulates c-Myc expression in colon cancer cells.
- Knockdown of RBM22 leads to reduced c-Myc stability.
Conclusions:
- RBM22 functions as a tumor suppressor in colon cancer.
- RBM22 regulates colon cancer cell proliferation and apoptosis through the c-Myc pathway.
- Targeting RBM22 may offer a therapeutic strategy for colon cancer.

01:31The Intrinsic Apoptotic Pathway
5.8K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

02:23Abnormal Proliferation
4.4K
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...

01:17The Extrinsic Apoptotic Pathway
5.7K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

01:06Induced Pluripotent Stem Cells
3.9K
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).

03:03mTOR Signaling and Cancer Progression
3.7K
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.

01:07MAPK Signaling Cascades
5.0K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
