BRAF-Mutated Melanoma Cell Lines Develop Distinct Molecular Signatures After Prolonged Exposure to AZ628 or Dabrafenib: Potential Benefits of the Antiretroviral Treatments Cabotegravir or Doravirine on BRAF-Inhibitor-Resistant Cells.

Melanoma is an aggressive cancer characterized by rapid growth, early metastasis, and poor prognosis, with resistance to current therapies being a significant issue. BRAF mutations drive uncontrolled cell division by activating the MAPK pathway. In this study, A375 and FO-1, BRAF-mutated melanoma cell lines, were treated for 4-5 months with RAF inhibitor dabrafenib or AZ628, leading to drug resistance over time.

Lamivudine, Doravirine, and Cabotegravir Downregulate the Expression of Human Endogenous Retroviruses (HERVs), Inhibit Cell Growth, and Reduce Invasive Capability in Melanoma Cell Lines.

This study explores the impact of antiretroviral administration on the expression of human endogenous retroviruses (HERVs), cell growth, and invasive capability of human melanoma cell lines in culture. We investigated three antiretrovirals-lamivudine, doravirine, and cabotegravir-in A375, FO-1, and SK-Mel-28, BRAF-mutated, and in MeWo, P53-mutated, melanoma cell lines. The findings indicate a general capability of these drugs to downregulate the expression of HERV-K Pol and Env genes and hinder cell viability, mobility, and colony formation capacity of melanoma cells.

Achievement of target LDL-cholesterol level in patients with acute coronary syndrome undergoing percutaneous coronary intervention: The JET-LDL registry.

Background: In patients with acute coronary syndromes (ACS), current guidelines recommend a low-density lipoprotein cholesterol (LDL-C) level < 1.4 mmol/L (<55 mg/dL).

Methods: The JET-LDL is a multicenter, observational, prospective registry created to investigate levels of LDL-C in consecutive patients with ACS undergoing PCI at 35 Italian hospitals, and to report their lipid lowering therapies (LLT).

Strengthening Warfighter Resiliency Using Broad-Spectrum or Host-Directed Therapies within the Rapid Acquisition and Investigation of Drugs for Repurposing Program.

To maintain cadence with looming threats in a prolonged field-care environment, the broader medical countermeasure (MCM) enterprise must adopt new strategies for chemical, biological, radiological, and nuclear (CBRN)-addressing drug development. The Countering Emerging Threats - Rapid Acquisition and Investigation of Drugs for Repurposing (CET RAIDR) program within the Joint Program Manager for CBRN Medical is designed to rapidly tackle known, unknown, and emerging threats by utilizing late-stage or licensed therapeutics. The focus of the CET RAIDR effort is to bridge treatment gaps between threat identification and the implementation of licensed targeted MCMs, thereby strengthening warfighter resiliency.
