Interplay between BRCA1 and RHAMM regulates epithelial apicobasal polarization and may influence risk of breast cancer.

open access: yesPLoS Biology, 2011
Differentiated mammary epithelium shows apicobasal polarity, and loss of tissue organization is an early hallmark of breast carcinogenesis. In BRCA1 mutation carriers, accumulation of stem and progenitor cells in normal breast tissue and increased risk ...

Expanding the Tyrosine Kinase Domain of CSF1R? A Case Report From an Adult‐Onset Leukoencephalopathy

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 8, August 2025.
ABSTRACT Adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), also termed hereditary diffuse leukoencephalopathy with spheroids‐1 (HDLS1), results from mutations in the CSF1R gene and leads to progressive leukoencephalopathy.

Evaluating eDNA Metabarcoding Techniques for Pollinator Community Assessment in a Field and Controlled Experiment

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
This study evaluates the use of environmental DNA (eDNA) metabarcoding on flowers to detect pollinator species and compares it with traditional visual sampling methods. Findings show that while eDNA complements conventional techniques in monitoring pollinators, it cannot fully replace them, highlighting the need for integrated approaches.

Case report: A Newly Identified G-protein Subunit α-11 Loss-of-Function Variant Causing Familial Hypocalciuric Hypercalcemia Type 2 in an Italian Kindred

open access: yesFrontiers in Endocrinology
BackgroundFHH2 is the rarest subtype of familial hypocalciuric hypercalcemia disorders affecting the CaSR signaling pathway. It is caused by heterozygous loss-of-function mutations in the GNA11 gene, encoding Gα11 protein.

Genome-wide association study in BRCA1 mutation carriers identifies novel loci associated with breast and ovarian cancer risk.

open access: yesPLoS Genetics, 2013
BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were

Coloration in Argia damselflies of Central Mexico responds to changes in herbaceous vegetation La coloración de caballitos del diablo del género Argia responde a cambios en la cobertura de vegetación herbácea en el Centro de México

open access: yesInsect Conservation and Diversity, Volume 18, Issue 4, Page 593-603, July 2025.
The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

Fostering Biodiversity in Neotropical Savannahs: Fire as a Diversity Driver for Fruit‐Feeding Butterfly Assemblages in the Cerrado

open access: yesAustral Ecology, Volume 50, Issue 3, March 2025.
The more frequently burnt areas with shorter time intervals since the last burn episode exhibited higher levels of biodiversity compared to sites where fires were less frequent and under longer intervals. ABSTRACT Fire has significantly shaped the dynamics of Brazilian Cerrado fauna and flora, but the interference of human activities and climate change
