Anticancer properties of non-psychoactive cannabinoid cannabidiol (CBD) have been demonstrated on tumors of different histogenesis. Different molecular targets for CBD were proposed, including cannabinoid receptors and some plasma membrane ion channels. Here we have shown that cell lines derived from acute lymphoblastic leukemia of T lineage (T-ALL), but not resting healthy T cells, are highly sensitive to CBD treatment. CBD effect does not depend on cannabinoid receptors or plasma membrane Ca-permeable channels. Instead, CBD directly targets mitochondria and alters their capacity to handle Ca. At lethal concentrations, CBD causes mitochondrial Ca overload, stable mitochondrial transition pore formation and cell death. Our results suggest that CBD is an attractive candidate to be included into chemotherapeutic protocols for T-ALL treatment.

Classification of non-TCGA cancer samples to TCGA molecular subtypes using compact feature sets.

Molecular subtypes, such as defined by The Cancer Genome Atlas (TCGA), delineate a cancer's underlying biology, bringing hope to inform a patient's prognosis and treatment plan. However, most approaches used in the discovery of subtypes are not suitable for assigning subtype labels to new cancer specimens from other studies or clinical trials. Here, we address this barrier by applying five different machine learning approaches to multi-omic data from 8,791 TCGA tumor samples comprising 106 subtypes from 26 different cancer cohorts to build models based upon small numbers of features that can classify new samples into previously defined TCGA molecular subtypes-a step toward molecular subtype application in the clinic.

In recent years, significant efforts have been made to improve methods for genomic studies of admixed populations using local ancestry inference (LAI). Accurate LAI is crucial to ensure that downstream analyses accurately reflect the genetic ancestry of research participants. Here, we test analytic strategies for LAI to provide guidelines for optimal accuracy, focusing on admixed populations reflective of Latin America's primary continental ancestries-African (AFR), Amerindigenous (AMR), and European (EUR).

Keloids are disfiguring proliferative scars, and their pathological mechanisms are still unclear. We have previously established that FoxC1 plays a significant role in rheumatoid arthritis and osteoarthritis, but its molecular mechanisms in pathological scar formation remain elusive. In this study, we analyzed keloid tissue characteristics using HE staining and immunohistochemistry, revealing abnormal expression of FoxC1 and Notch3 in keloids.

Introduction: Placental extracellular vesicles (EVs), lipid-enclosed particles released from the placenta, can facilitate intercellular communication and are classified as micro- or nano-EVs depending on size. Placental EVs contain molecules associated with cell proliferation and death. In this study, we investigated whether treating human ovarian tumour explants with placental EVs could induce ovarian tumour cell death.

Carbon nanotubes (CNTs) has emerged as a promising nanomaterial with a wide range of potential applications due to their unique structural, mechanical, electrical, and thermal properties. However, numerous obstacles must be overcome for CNTs to be used successfully, including low solubility, aggregation, and a lack of specialized functions. Diverse techniques have been developed for the manufacture, purification, and functionalization of CNTs in order to overcome these issues.
