PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Genetics of inbred Drosophila melanogaster VI. Crossing-over in secondary non-disjunction exceptionals [PDF]

open access: yesHereditas, 2008
Although Bridges (1916, Genetics 1: 1–52 and 107–183) found recombinants among exceptional XXY females in tests of secondary non-disjunction, he misinterpreted their origin and claimed that true secondary non-disjunction resulted in XX eggs with non-crossover chromosomes.

A wheat chromosome segment substitution line series supports characterization and use of progenitor genetic variation

open access: yesThe Plant Genome
Genome‐wide introgression and substitution lines have been developed in many plant species, enhancing mapping precision, gene discovery, and the identification and exploitation of variation from wild relatives.

Genetic Renal Diseases: The Emerging Role of Zebrafish Models

open access: yesCells, 2018
The structural and functional similarity of the larval zebrafish pronephros to the human nephron, together with the recent development of easier and more precise techniques to manipulate the zebrafish genome have motivated many researchers to model human

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Development of high yielding and stress resilient post-rainy season sorghum cultivars using a multi-parent crossing approach

open access: yesScientific Reports
Modern agriculture, based on biparental crop varieties have contributed tremendously to the world’s food supply. However, the strategy is also being challenged due to stagnation in yield growth, climate change, susceptibility to biotic and abiotic ...

Floral biology and reproductive mechanisms of Mussambê (Cleome spinosa Jacq) aiming at the plant breeding [PDF]

open access: yesBiotemas, 2007
Some plants from Cleome genus in Capparaceae family are used as medicinal and ornamental plants. The aim of this work was to study the fl oral biology and the reproductive mechanisms of C. spinosa to the plant breeding. Anthesis occurred between 17:30 to
