Aging is a continuous process leading to physiological deterioration with age. One of the factors contributing to aging is telomere shortening, causing alterations in the protein protective complex named shelterin and replicative senescence. Here, we address the question of the link between this telomere shortening and the transcriptional changes occurring in senescent cells.

Abiraterone acetate (AA) is the first-in-class of drugs belonging to the second-generation of agents inhibiting androgen neosynthesis in advanced prostate cancer. A cumulative experience attests that germinal gene polymorphisms may play a role in the prediction of anticancer agent pharmacodynamics variability. In the present prospective, multicentric study, gene polymorphisms of CYP17A1 (AA direct target) and the androgen transporter genes SLCO2B1 and SLCO1B3 (potential modulators of AA activity) were confronted with AA pharmacodynamics (treatment response and toxicity) in a group of 137 advanced prostate cancer patients treated in the first line by AA.

Article Synopsis
  • - The study explored how anti-angiogenic treatment targeting VEGF and its receptors in metastatic clear cell renal cell carcinoma (ccRCC) shows variable effectiveness among patients, aiming to understand the cause of this variability for better therapy options.
  • - Researchers identified novel splice variants of the VEGF gene that are less effectively targeted by current treatments, with specific changes in the VEGF protein potentially influencing tumor behavior and angiogenesis.
  • - Findings from both in vitro and in vivo experiments demonstrated that overexpression of these new VEGF variants promotes tumor growth and vascularization, while higher plasma levels of VEGF were linked to poorer survival rates and reduced effectiveness of anti-angiogenic therapies in ccRCC patients.

Determinants of humoral immune response to SARS-CoV-2 vaccines in solid cancer patients: A systematic review and meta-analysis.

Vaccine

March 2023

Laboratory of Clinical and Experimental Pathology, Pasteur Hospital, University Côte d'Azur, 30 avenue de la voie romaine, 06002 Nice, France; Institute for Research on Cancer and Ageing, Nice (IRCAN), INSERM U1081 and UMR CNRS 7284, Team 4, Nice, France; Hospital-Integrated Biobank BB-0033-00025, Pasteur Hospital, Nice, France; University Hospital Federation OncoAge, CHU de Nice, University Côte d'Azur, Nice, France.

Importance: Solid cancer patients following SARS-CoV-2 vaccination are likely to have a lower seroconversion rate than healthy adults. Seroconversion between those with and without cancer is likely to vary moderately or to be restricted to specific subgroups. Therefore, we sought to conduct a systematic review and meta-analysis to identify risk factors for diminished humoral immune responses in solid cancer patients.

Sustainable Composites from Nature to Construction: Hemp and Linseed Reinforced Biocomposites Based on Bio-Based Epoxy Resins.

Materials (Basel)

February 2023

Aitiip Centro Tecnológico, Research and Development Department, 50720 Zaragoza, Spain.

The present manuscript describes the use of natural fibers as natural and sustainable reinforcement agents for advanced bio-based composite materials for strategic sectors, for example, the construction sector. The characterization carried out shows the potential of both natural hemp and linseed fibers, as well as their composites, which can be used as insulation materials because their thermal conductivity properties can be compared with those observed in typical construction materials such as pine wood. Nevertheless, linseed composites show better mechanical performance and hemp has higher fire resistance.

Photoprotection for people with skin of colour: needs and strategies.

Br J Dermatol

February 2023

Photomedicine and Photobiology Unit, Department of Dermatology, Henry Ford Health, Detroit, MI, USA.

Skin of colour or pigmented skin has unique characteristics: it has a higher eumelanin-to-pheomelanin ratio, more mature melanosomes, an increased amount of melanin distributed in the upper layers of the epidermis, and more efficient DNA repair compared with lighter skin. However, individuals with skin of colour are at a significant risk of skin damage caused by ultraviolet radiation, including the development of photodermatoses and photoageing changes such as uneven skin tone, and are predisposed to pigmentary disorders. In fact, one of the most common conditions leading to dermatology consultations by patients with skin of colour is photoexacerbated pigmentary disorders.

Electronic address:

Article Synopsis
  • - Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer, and current treatment for advanced cases often relies on immune-checkpoint inhibitors; however, their effectiveness can be limited.
  • - A study aimed to investigate the frequency of BRCA1/2 mutations in MCC, finding only one pathogenic BRCA2 variant among 30 samples, leading to a confirmed low rate of such mutations (around 3%) in MCC cases overall.
  • - Although BRCA1/2 mutations are rare in MCC, they could present a potential target for treatment with poly-(ADP-Ribose)-polymerase inhibitors, but this requires further validation through clinical trials.

N-methyl-D-aspartate receptors (NMDARs) are critical for the maturation and plasticity of glutamatergic synapses. In the hippocampus, NMDARs mainly contain GluN2A and/or GluN2B regulatory subunits. The amyloid precursor protein (APP) has emerged as a putative regulator of NMDARs, but the impact of this interaction to their function is largely unknown.

Glutathione peroxidase 4 (GPX4) has been reported as one of the major targets for ferroptosis induction, due to its pivotal role in lipid hydroperoxide removal. However, recent studies pointed toward alternative antioxidant systems in this context, such as the Coenzyme Q-FSP1 pathway. To investigate how effective these alternative pathways are in different cellular contexts, we used human colon adenocarcinoma (CRC) cells, highly resistant to GPX4 inhibition.

To directly compare five commonly used on-field systems (motorized linear encoder, laser, radar, global positioning system, and timing gates) during sprint acceleration to (i) measure velocity−time data, (ii) compute the main associated force−velocity variables, and (iii) assess their respective inter-trial reliability. Eighteen participants performed three 40 m sprints, during which five systems were used to simultaneously and separately record the body center of the mass horizontal position or velocity over time. Horizontal force−velocity mechanical outputs for the two best trials were computed following an inverse dynamic model and based on an exponential fitting of the position- or velocity-time data.

The medical literature on aesthetic dermatology has primarily focused on a light-skinned patient population, yet patients of darker skin types have different needs and priorities. In Chinese individuals, key concerns include altered pigmentation, which is perceived to age the individual, and also relates to the Chinese cultural standard of beauty of fair skin; many seek aesthetic treatment for this. Non-invasive cosmetic procedures such as lasers and injections are also gaining in popularity in the Chinese market, but this population is prone to hyperpigmentation as an adverse effect of such procedures.
