Summary
Long noncoding RNAs (lncRNAs) regulate crucial cellular processes like apoptosis. Dysregulation of lncRNAs impacts cancer and neurodegeneration, offering potential therapeutic targets and biomarkers.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- The mammalian genome is extensively transcribed, with noncoding RNAs comprising a significant portion of cellular RNA.
- Long noncoding RNAs (lncRNAs) are emerging as key regulators in physiological and pathological processes, including cancer and neurodegeneration.
- Apoptosis, or programmed cell death, is vital for development and homeostasis, and its dysregulation is a hallmark of cancer.
Purpose of the Study:
- To review current research on the role of lncRNAs in apoptosis.
- To highlight the involvement of lncRNAs in cancer cell apoptosis and differentiation.
- To explore the potential of lncRNAs as anticancer drug targets and tumor biomarkers.
Main Methods:
- Literature review of recent studies on lncRNAs and apoptosis.
- Focus on studies involving cancer cells and healthy cells during differentiation.
- Analysis of data correlating lncRNA expression with cancer types.
Main Results:
- lncRNAs are implicated in modulating apoptosis in both physiological and cancer contexts.
- Specific lncRNAs can sensitize cancer cells to apoptosis when overexpressed or downregulated.
- lncRNA expression levels correlate with distinct cancer types.
Conclusions:
- lncRNAs represent a novel class of molecules with significant roles in apoptosis regulation.
- Targeting lncRNAs holds promise for developing new anticancer therapies.
- lncRNAs show potential as diagnostic and prognostic biomarkers for various cancers.

01:31The Intrinsic Apoptotic Pathway
6.2K
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...

01:17The Extrinsic Apoptotic Pathway
6.2K
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...

02:39lncRNA - Long Non-coding RNAs
7.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:30Apoptosis
12.0K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:22Cellular Injury V: Apoptosis and Autophagy
99
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...

01:24Caspases
8.7K
Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...
