Tumor Progression

Tumor Progression

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...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

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...

Yeast Signaling

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

Co-activators and Co-repressors

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

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...

Summary

Bioresorbable scaffolds (BRS) offer temporary vessel support during percutaneous coronary intervention (PCI), promoting healing without a permanent metal cage. This allows for natural vessel function post-absorption, unlike traditional stents.

Background:

Bioresorbable scaffolds (BRS) are an emerging technique in percutaneous coronary intervention (PCI).
BRS provide temporary vessel support, ensuring patency and acute benefits during the early treatment phase.
Unlike permanent metal stents, BRS are designed to gradually resorb after fulfilling their function.

Purpose of the Study:

To review the research background of bioresorbable scaffolds (BRS).
To discuss the current status and challenges associated with BRS in clinical practice.
To explore the future development trends of BRS technology.

Main Methods:

Literature review of existing research on bioresorbable scaffolds.
Analysis of the performance and resorption characteristics of BRS.
Comparative assessment of BRS against traditional metallic stents.

Main Results:

BRS facilitate temporary vessel support and patency.
Complete resorption of BRS allows for positive late vessel remodeling.
Potential for stent-free outcomes, particularly in bifurcation lesions, is a key advantage.

Conclusions:

BRS offer a unique alternative to permanent metal stents in PCI.
The ability of BRS to disappear promotes natural vessel healing and function.
Further research and development are crucial to overcome current challenges and optimize BRS technology.
