Phototropin 2 mediates daily cold priming to promote light responses in Arabidopsis.

Organisms adapt to predictable environmental changes via a biological mechanism called priming. Phototropin (phot) is a plant-specific blue light photoreceptor that mediates daily light-induced responses, such as chloroplast relocation, stomatal opening, and phototropism, to optimize photosynthesis. Phot also functions as a thermosensor for chloroplast relocation that may sense daily temperature decreases at night, thereby modulating light-induced responses at dawn; however, this hypothesis has not yet been fully explored.

Identifying metabolomic mediators of the physical activity and colorectal cancer relationship.

Background: Current evidence suggests higher physical activity (PA) levels are associated with a reduced risk of colorectal cancer (CRC). However, the mediating role of the circulating metabolome in this relationship remains unclear.

Methods: Targeted metabolomics data from 6,055 participants in the EPIC cohort were used to identify metabolites associated with PA and derive a metabolomic signature of PA levels.

Molecular and therapeutic insight into ER Stress signaling in NSCLC.

Endoplasmic Reticulum (ER) stress is intricately involved in cancer development, progression and response to chemotherapy. ER stress related genes might play an important role in predicting the prognosis in lung adenocarcinoma patients and may be manipulated to improve the treatment outcome and overall survival rate. In this review, we analyzed the contribution of the three major ER stress pathways-IRE1, ATF6, and PERK-in lung cancer pathogenesis via modulation of tumor microenvironment (TME) and processes as metastasis, angiogenesis, apoptosis and N-glycosylation.

The role of green synthesis metal and metal oxide nanoparticles in oral cancer therapy: a review.

There are 275,000 new cases of oral cancer (OC) per year, making it the sixth most common cancer in the world. Severe adverse effects, including loss of function, deformity, and systemic toxicity, are familiar with traditional therapies such as radiation, chemotherapy, and surgery; due to their unique properties, nanoparticles (NPs) have emerged as a superior alternative over chemo/radiotherapy and surgery due to their targeting capability, bioavailability, compatibility, and high solubility. Due to their unique properties, metallic NPs have garnered significant attention in OC control.

Copaiba essential oil carried in a self-nanoemulsifying drug delivery system improves adjuvant-induced arthritis in rats.

Objectives: Copaiba essential oil (CEO) is obtained through the distillation of copaiba balsam and has been used in the traditional medicine to treat inflammatory conditions. However, the highly lipophilic nature of CEO restricts its pharmaceutical use. This study evaluated the effect of CEO, carried in a self-nanoemulsifying drug delivery system (SNEDDS), on articular and systemic inflammation and liver changes in Holtzman rats with Freund's adjuvant-induced arthritis.

Exome sequencing reveals a sparse genomic landscape in Kaposi sarcoma.

Kaposi Sarcoma (KS) is a frequently aggressive malignancy caused by Kaposi sarcoma herpesvirus (KSHV/HHV-8). People with immunodeficiencies, including HIV, are at increased risk for developing KS, but our understanding of the contributions of the cellular genome to KS pathogenesis remains limited. To determine if there are cellular genetic alterations in KS that might provide biological or therapeutic insights, we performed whole exome sequencing on 78 KS tumors and matched normal control skin from 59 adults with KS (46 with HIV-associated KS and 13 with HIV-negative KS) receiving treatment at the Uganda Cancer Institute in Kampala, Uganda.

Exploring RNA modifications in infectious non-coding circular RNAs.

Viroids, small circular non-coding RNAs, act as infectious pathogens in higher plants, demonstrating high stability despite consisting solely of naked RNA. Their dependence of replication on host machinery poses the question of whether RNA modifications play a role in viroid biology. Here, we explore RNA modifications in the avocado sunblotch viroid (ASBVd) and the citrus exocortis viroid (CEVd), representative members of viroids replicating in chloroplasts and the nucleus, respectively, using LC - MS and Oxford Nanopore Technology (ONT) direct RNA sequencing.

Dedenser: A Python Package for Clustering and Downsampling Chemical Libraries.

The screening of chemical libraries is an essential starting point in the drug discovery process. While some researchers desire a more thorough screening of drug targets against a narrower scope of molecules, it is not uncommon for diverse screening sets to be favored during the early stages of drug discovery. However, a cost burden is associated with the screening of molecules, with potential drawbacks if particular areas of chemical space are needlessly overrepresented.
