1Massachusetts General Hospital Cancer Center, Boston, Massachusetts. rsullivan7@mgh.harvard.edu.
Summary
Targeting BRAF in BRAF-mutant melanoma is effective, but resistance emerges. Heat shock protein 90 (HSP90) is a potential therapeutic target to overcome this resistance in melanoma treatment.
Area of Science:
- Oncology
- Molecular Biology
- Drug Discovery
Background:
- BRAF inhibitors are effective against BRAF-mutant melanoma.
- Acquired resistance limits the long-term efficacy of BRAF-targeted therapy.
- Heat shock protein 90 (HSP90) is implicated in resistance mechanisms.
Purpose of the Study:
- To investigate HSP90 as a potential therapeutic target in BRAF-mutant melanoma.
- To explore strategies to overcome resistance to BRAF inhibitors.
Main Methods:
- Review of existing literature on BRAF inhibitors and resistance in melanoma.
- Discussion of the role of HSP90 in cancer cell survival and drug resistance.
- Consideration of clinical trial designs for HSP90-targeted therapies.
Main Results:
- BRAF inhibition is a validated strategy for melanoma but is hampered by resistance.
- HSP90 stabilization is a key mechanism contributing to resistance.
- Targeting HSP90 may re-sensitize melanoma to BRAF inhibitors.
Conclusions:
- HSP90 represents a promising therapeutic target to overcome BRAF inhibitor resistance in melanoma.
- Early-stage clinical trials are needed to validate HSP90-targeted approaches.
- Randomized trials may be required to confirm the efficacy of combining BRAF and HSP90 inhibition.

11.0K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.

While deriving the Doppler formula for the observed frequency of a sound wave, it is assumed that the speed of sound in the medium is greater than the source's speed through it. When this condition is breached, a shock wave occurs.
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

4.6K
When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:

6.0K
When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

In circuit analysis, situations often arise where resistors are neither in series nor parallel configurations. To tackle such scenarios, three-terminal equivalent networks like the wye (Y) (Figure 1 (a)) or tee (T) and delta (Δ) (Figure 1 (b)) or pi (π) networks come into play. These networks offer versatile solutions and are frequently encountered in various applications, including three-phase electrical systems, electrical filters, and matching networks.

01:25Resistance and Conductance

A conductor's DC resistance at a given temperature is influenced by its resistivity, length, and cross-sectional area. Resistivity is an inherent property of the conductor material, with annealed copper serving as the international standard for measurement. For instance, the resistivity of hard-drawn aluminum at 20 degrees Celsius is 61% of the standard conductivity of annealed copper.
