Impacting elementary STEM teacher leadership identities

open access: yesSchool Science and Mathematics, Volume 125, Issue 5, Page 519-531, October 2025.
Abstract Learning science, technology, engineering, and mathematics (STEM) subjects starting at a young age helps prepare students for a variety of careers both inside and outside of the sciences. Yet, addressing integrated STEM in an elementary school setting can be challenging. Teacher leadership is one way to address this challenge.

Zinc antagonizes cadmium-induced osteoporosis in mice by inhibiting Cd2+ deposition, enhancing antioxidant capacity and correcting bone metabolic disorders

open access: yesEcotoxicology and Environmental Safety
Chronic cadmium (Cd) exposure is a recognized risk factor for osteoporosis. Zinc (Zn) plays crucial roles in bone metabolism, yet intervention roles of Zn2+ against Cd-induced osteoporosis are incompletely understood.

Zinc-induced Dnmt1 expression involves antagonism between MTF-1 and nuclear receptor SHP [PDF]

open access: yes, 2011
Dnmt1 is frequently overexpressed in cancers, which contributes significantly to cancer-associated epigenetic silencing of tumor suppressor genes. However, the mechanism of Dnmt1 overexpression remains elusive.

Emerging Roles of Metallothioneins in Human Pathophysiology: A Review

open access: yesHealth Science Reports, Volume 8, Issue 9, September 2025.
ABSTRACT Background Metallothioneins (MTs) are small molecular‐weight proteins that either bind or release essential transition metals, depending on a specific cell situation. There are 4 major isoforms of MTs (1–4), of which MT1/2 is found in every cell in the body.

Eukaryotic initiation factor 5A dephosphorylation is required for translational arrest in stationary phase cells [PDF]

open access: yes, 2013
The protein known as eIF5A (eukaryotic initiation factor 5A) has an elusive role in translation. It has a unique and essential hypusine modification at a conserved lysine residue in most eukaryotes.

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

Characterization of MtnE, the fifth metallothionein member in Drosophila [PDF]

open access: yes, 2018
Metallothioneins (MTs) constitute a family of cysteine-rich, low molecular weight metal-binding proteins which occur in almost all forms of life. They bind physiological metals, such as zinc and copper, as well as nonessential, toxic heavy metals, such ...

An allelic variant in the intergenic region between ERAP1 and ERAP2 correlates with an inverse expression of the two genes [PDF]

open access: yes, 2018
The Endoplasmatic Reticulum Aminopeptidases ERAP1 and ERAP2 are implicated in a variety of immune and non-immune functions. Most studies however have focused on their role in shaping the HLA class I peptidome by trimming peptides to the optimal size ...

Exosomes, autophagy, and cancer: A complex triad

open access: yesInternational Journal of Cancer, Volume 157, Issue 3, Page 405-415, 1 August 2025.
Abstract Cancer remains one of the leading causes of death worldwide. Despite remarkable progress in prevention, diagnosis, and therapy, the incidence of certain types of cancer persists, urging the identification of clinically relevant biomarkers and the development of novel therapeutic strategies to improve clinical outcomes and overcome treatment ...

A cross‐sectional study evaluating the frequency of HIV drug resistance mutations among individuals diagnosed with HIV‐1 in tenofovir disoproxil fumarate‐based pre‐exposure prophylaxis rollout programmes in Kenya, Zimbabwe, Eswatini and South Africa

open access: yesJournal of the International AIDS Society, Volume 28, Issue 8, August 2025.
Abstract Introduction The ongoing rollout of oral tenofovir‐based pre‐exposure prophylaxis (PrEP) has the potential to reduce HIV‐1 incidence, but HIV drug resistance (HIVDR) in individuals who acquire HIV‐1 on PrEP could threaten the treatment effectiveness of overlapping antiretrovirals (tenofovir/emtricitabine), contribute to development of ...
