Comparative genomic analysis reveals a critical role of de novo nucleotide biosynthesis for Saccharomyces cerevisiae virulence.

PLoS ONE, 2015
In recent years, the number of human infection cases produced by the food related species Saccharomyces cerevisiae has increased. Whereas many strains of this species are considered safe, other 'opportunistic' strains show a high degree of potential ...

Aerobic prokaryotes do not have higher GC contents than anaerobic prokaryotes, but obligate aerobic prokaryotes have

BMC Evolutionary Biology, 2019
Background Among the four bases, guanine is the most susceptible to damage from oxidative stress. Replication of DNA containing damaged guanines results in G to T mutations.

Tomato EF-Tsmt, a functional mitochondrial translation elongation factor from higher plants [PDF]

, 2003
Ethylene-induced ripening in tomato (Lycopersicon esculentum) resulted in the accumulation of a transcript designated LeEF-Tsmt that encodes a protein with significant homology to bacterial Ts translational elongation factor (EF-Ts).

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

Glucocorticoids rapidly inhibit oxytocin-stimulated adrenocorticotropin release from rat anterior pituitary cells, without modifying intracellular calcium transients [PDF]

, 1993
Glucocorticoid hormones suppress the secretion of ACTH evoked by secretagogues such as CRF and arginine vasopressin. In this study, we investigated the effects of glucocorticoids on ACTH release induced by oxytocin (OT) and on intracellular free calcium ...

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

International Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

A Pan‐Cancer Single‐Cell Atlas of Bone Metastases Reveals Convergent Malignant Programs and Coordinated Immune Dysfunction

iMetaMed, EarlyView.
A pan‐cancer atlas deciphers tumor‐induced reprogramming in bone metastases. Malignant evolution toward MYC/proliferation is a hallmark of bone metastases. Niche‐mediated immune dysfunction is characterized by immature pDCs, impaired antigen presentation and phagocytosis in TAMs, and exhausted T cells.
