The prognostic value of BRAF V600 mutation level on clinical outcomes in patients with BRAF V600-mutated metastatic melanoma treated with BRAF and MEK inhibitors remains uncertain. The association was retrospectively analysed between BRAF V600 mutation level (defined as the ratio of the quantification of the BRAF V600 allele to the percentage of tumoral cells in the sample analysed) and progression-free and overall survival (PFS and OS, respectively) and 3-month response rate in a cohort of 58 patients with metastatic melanoma who harboured BRAF V600E/K mutations and received dual targeted-therapy BRAF/MEK inhibitors. The BRAF mutation level cut-off determined by the area under the receiver operating characteristic curve after internal validation by bootstrap methods was 0.

Article Synopsis
  • - Jasmonate is a crucial hormone in plants that helps regulate development and responses to stress, primarily through the COI receptor which targets specific repressors for degradation, leading to the activation of defense genes.
  • - In rice, three COI genes (OsCOI1a, OsCOI1b, and OsCOI2) play important roles, with OsCOI2 recently identified as key in transcriptional changes during jasmonate signaling, particularly linked to root development and stress response.
  • - Mutations in OsCOI2 result in less effective responses to jasmonate compared to other COI genes, suggesting that OsCOI2 significantly influences the balance between growth and defense while also affecting the plant's

 Alzheimer's disease and cerebral amyloid angiopathy (CAA) are often associated. Amyloid accumulation within leptomeningeal and small/median-sized cerebral blood vessels in CAA results in vessel fragility, leading to spontaneous leptomeningeal bleeding, lobar intracerebral hemorrhage (ICH) and cerebral microbleeds. CAA is also associated with non-traumatic subdural hematoma.

Warming and trophic structure tightly control phytoplankton bloom amplitude, composition and succession.

PLoS One

October 2024

MARBEC (Marine Biodiversity, Exploitation and Conservation), Univ Montpellier, CNRS, Ifremer, IRD, Montpellier, France.

To better identify the responses of phytoplankton blooms to warming conditions as expected in a climate change context, an in situ mesocosm experiment was carried out in a coastal Mediterranean lagoon (Thau Lagoon, South of France) in April 2018. Our objective was to assess both the direct and indirect effects of warming on phytoplankton, particularly those mediated by top-down control. Four treatments were applied: 1) natural planktonic community with ambient water temperature (C); 2) natural planktonic community at +3°C elevated temperature (T); 3) exclusion of larger zooplankton (> 200 μm; mesozooplankton) leaving microzooplankton predominant with ambient water temperature (MicroZ); and 4) exclusion of larger zooplankton (> 200 μm; mesozooplankton) at +3°C elevated temperature (TMicroZ).
