Functional genomics of abiotic environmental adaptation in lacertid lizards and other vertebrates. The journal of animal ecology, https://doi.org/10.1111/1365-2656.13617

Understanding the genomic basis of adaptation to different abiotic environments is important in the context of climate change and resulting short-term environmental fluctuations. Using functional and comparative genomics approaches, we here investiga... Read More about Functional genomics of abiotic environmental adaptation in lacertid lizards and other vertebrates.

Journal Article
Scott, V. F., Feugere, L., Wollenberg Valero, K. C., Scott, V., Rodriguez-Barucg, Q., & Beltran-Alvarez, P. (2021). Thermal stress induces a positive phenotypic and molecular feedback loop in zebrafish embryos. Journal of Thermal Biology, 102, https://doi.org/10.1016/j.jtherbio.2021.103114

Aquatic organisms must cope with both rising and rapidly changing temperatures. These thermal changes can affect numerous traits, from molecular to ecological scales. Biotic stressors are already known to induce the release of chemical cues which tri... Read More about Thermal stress induces a positive phenotypic and molecular feedback loop in zebrafish embryos.

Arginine methylation: the promise of a ‘silver bullet’ for brain tumours? (2021)
Journal Article
Samuel, S. F., Barry, A., Greenman, J., & Beltran-Alvarez, P. (in press). Arginine methylation: the promise of a ‘silver bullet’ for brain tumours?. Amino acids, https://doi.org/10.1007/s00726-020-02937-x

Despite intense research efforts, our pharmaceutical repertoire against high-grade brain tumours has not been able to increase patient survival for a decade and life expectancy remains at less than 16 months after diagnosis, on average. Inhibitors of... Read More about Arginine methylation: the promise of a ‘silver bullet’ for brain tumours?.

The inhibitory subunit of cardiac troponin (cTnI) is modified by arginine methylation in the human heart (2019)
Journal Article
Onwuli, D. O., Samuel, S., Sfyri, P., Welham, K., Goddard, M., Abu-Omar, Y., …Beltran-Alvarez, P. (2019). The inhibitory subunit of cardiac troponin (cTnI) is modified by arginine methylation in the human heart. International journal of cardiology, 282, 76-80. https://doi.org/10.1016/j.ijcard.2019.01.102

Background The inhibitory subunit of cardiac troponin (cTnI) is a gold standard cardiac biomarker and also an essential protein in cardiomyocyte excitation-contraction coupling. The interactions of cTnI with other proteins are fine-tuned by post-tra... Read More about The inhibitory subunit of cardiac troponin (cTnI) is modified by arginine methylation in the human heart.

Inhibiting arginine methylation as a tool to investigate cross-talk with methylation and acetylation post-translational modifications in a glioblastoma cell line (2018)
Journal Article

Proteomes, 6(4), https://doi.org/10.3390/proteomes6040044

Glioblastomas (GBM) are the most common grade 4 brain tumours; patients have very poor prognosis with an average survival of 15 months after diagnosis. Novel research lines have begun to explore aberrant protein arginine methylation (ArgMe) as a poss...

Attenuation of oxidative stress-induced lesions in skeletal muscle in a mouse model of obesity-independent hyperlipidaemia and atherosclerosis through the inhibition of Nox2 activity (2018)
Journal Article
Sfyri, P. P., Yuldasheva, N. Y., Tzimou, A., Giallourou, N., Crispi, V., Aburima, A., …Matsakas, A. (2018).

Free radical biology & medicine, 129, 504-519. https://doi.org/10.1016/j.freeradbiomed.2018.10.422

Obesity leading to hyperlipidaemia and atherosclerosis is recognised to induce morphological and metabolic changes in many tissues. However, hyperlipidaemia can occur in the absence of obesity. The impact of the latter scenario on skeletal muscle and...
