Unraveling the advances of non-coding RNAs on the tumor microenvironment: innovative strategies for cancer therapies.

Non-coding RNAs (ncRNAs) are crucial molecules that do not encode proteins but play roles in regulating various biological processes. Recent research highlights that ncRNAs not only control gene expression within cells but also facilitate intercellular communication via exosomes and other carriers. This function is vital in the tumor microenvironment (TME). Our review covers the structure and functions of different ncRNAs, such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs). We examine how these ncRNAs influence tumor initiation and progression. Additionall

Exploration of Site-Specific Drug Targeting-A Review on EPR-, Stimuli-, Chemical-, and Receptor-Based Approaches as Potential Drug Targeting Methods in Cancer Treatment.

Cancer has been one of the most dominant causes of mortality globally over the last few decades. In cancer treatment, the selective targeting of tumor cells is indispensable, making it a better replacement for conventional chemotherapies by diminishing their adverse side effects. While designing a drug to be delivered selectively in the target organ, the drug development scientists should focus on various factors such as the type of cancer they are dealing with according to which drug, targeting moieties, and pharmaceutical carriers should be targeted. All published articles have been collecte

Emerging predictive biomarkers for novel therapeutics in peripheral T-cell and natural killer/T-cell lymphoma.

Peripheral T-cell lymphoma (PTCL) and natural killer/T-cell lymphoma (NKTCL) are rare subtypes of non-Hodgkin's lymphoma that are typically associated with poor treatment outcomes. Contemporary first-line treatment strategies generally involve the use of combination chemoimmunotherapy, radiation and/or stem cell transplant. Salvage options incorporate a number of novel agents including epigenetic therapies (e.g. HDAC inhibitors, DNMT inhibitors) as well as immune checkpoint inhibitors.

Mechanisms of cancer-associated thrombosis.

A State-of-the-Art lecture titled "Mechanisms of cancer-associated thrombosis" was presented at the ISTH Congress in 2022. Patients with cancer have a 4-fold to 9-fold increased risk of venous thromboembolism (VTE) compared with the general population, so-called cancer-associated thrombosis (CAT). Different rates of VTE are observed in different types of cancer, suggesting that there are cancer-type specific mechanisms of CAT. We will discuss 4 pathways of CAT: tissue factor, podoplanin, neutrophil extracellular traps, and plasminogen activator inhibitor-1. In addition, specific gene mutations

Drug repurposing in oncology: Compounds, pathways, phenotypes and computational approaches for colorectal cancer.

The strategy of using existing drugs originally developed for one disease to treat other indications has found success across medical fields. Such drug repurposing promises faster access of drugs to patients while reducing costs in the long and difficult process of drug development. However, the number of existing drugs and diseases, together with the heterogeneity of patients and diseases, notably including cancers, can make repurposing time consuming and inefficient. The key question we address is how to efficiently repurpose an existing drug to treat a given indication. As drug efficacy rem
