Summary
Survivin, a protein inhibiting apoptosis, is crucial for adult stem cells and cancer progression. Targeting Survivin offers a promising strategy for treating various cancers like carcinomas, sarcomas, and leukemias.
Area of Science:
- * Molecular Biology
- * Cancer Biology
- * Stem Cell Biology
Background:
- * Inhibitors of Apoptosis proteins (IAPs) were initially identified for their role in preventing programmed cell death.
- * Survivin, an IAP member, is vital for cell cycle regulation, chromosomal segregation, and adult stem cell maintenance.
- * Aberrant Survivin expression is common in cancers, promoting tumor growth and survival.
Purpose of the Study:
- * To explore the rationale for targeting Survivin as an anticancer therapeutic.
- * To examine Survivin's role in various cancer types, including carcinomas, sarcomas, and leukemias.
- * To review Survivin's regulation by cancer signaling pathways, genetic variations (SNPs), and microRNAs (miRNAs).
Main Methods:
- * Review of existing literature on Survivin's function and therapeutic targeting.
- * Analysis of Survivin's involvement in cancer pro-survival signaling.
- * Examination of the relationship between Survivin single nucleotide polymorphisms (SNPs) and tumorigenesis.
- * Investigation of Survivin regulation by miRNAs.
- * Comparison of cell growth, clonogenic potential, and apoptosis under different inhibition strategies.
Main Results:
- * Survivin overexpression is linked to enhanced cell proliferation, survival, and resistance to apoptosis in cancer cells.
- * Survivin's role in adult stem cell maintenance suggests potential on-target toxicities with therapeutic inhibition.
- * Genetic variations (SNPs) in the Survivin gene may influence cancer risk and progression.
- * miRNAs play a significant role in regulating Survivin expression and function.
- * Various strategies, including gene expression and protein activity modulation, are being explored for Survivin inhibition.
Conclusions:
- * Survivin is a validated therapeutic target due to its critical role in cancer cell survival and proliferation.
- * Understanding Survivin's complex regulation by signaling pathways, genetics, and miRNAs is essential for effective therapeutic development.
- * Diverse approaches to inhibit Survivin, targeting gene expression or protein activity, hold promise for cancer treatment.

7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:31The Intrinsic Apoptotic Pathway
6.5K
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...

7.6K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:20The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:34Inhibition of Cdk Activity
4.7K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

02:50Combination Therapies and Personalized Medicine
4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
