Use of new compound such as inhibitors of JAK2 or transforming growth factor β-like molecules might soon revolutionize the treatment of β-thalassemia and related disorders. However, this situation requires careful optimization, noting the potential for off-target immune suppression for JAK2 inhibitors and the lack of mechanistic insights for the use of the ligand trap soluble molecules that sequester ligands of activin receptor IIA and B.

Anemia remains a widespread public health concern, and the search for interventions demonstrating potent anti-anemic activity is critical for reducing its impact among high-risk populations. Conventional iron therapies are associated with several complications and potential adverse effects. This study explored a polyherbal approach to develop a safer and more effective alternative treatment for anemia.

Individual responses to exercise training vary widely, shaping athletic performance, rehabilitation outcomes and long‑term health trajectories. This review synthesizes evidence on how angiotensin-converting enzyme (ACE) activity, influenced by genetic variation, epigenetic regulation and pharmacological modulation, shapes adaptations in skeletal muscle hypertrophy, cardiac remodelling, erythropoiesis, endurance capacity and injury susceptibility. We highlight ACE's nuanced role, showing that pharmacological inhibition selectively attenuates cardiac and haematological adaptations, such as haemoglobin mass and lean body mass, without affecting peripheral muscle adaptations and aerobic performance.

High-altitude environments, characterized by hypoxia, low temperatures, and intense ultraviolet radiation, pose significant challenges to human physiology and health. DNA methylation, as a key epigenetic regulatory mechanism, plays a central role in human adaptation to high-altitude environments and in disease pathogenesis. Current research indicates that high-altitude native populations (such as Tibetans and Andeans) modulate the methylation of hypoxia-responsive genes like EPAS1 and EGLN1 to enhance oxygen transport efficiency and energy metabolism patterns, while simultaneously suppressing excessive erythropoiesis and oxidative stress damage.

Background & objectives Genetic defects and altered synthesis of RBCs characterise β-thalassemia and polycythaemia vera (PV), respectively. In both diseases, stress erythropoiesis leads to accelerated erythroid expansion, although iron regulation has not been well studied. Here, we analysed iron parameters and iron regulatory gene expression in individuals affected with β-thalassemia and PV.

Background: Vaccine-driven evolution can erode the beneficial effects of vaccination and is a concern, especially for newly introduced vaccines. While obvious candidates for vaccine-driven evolution are the precise parasite antigens that are the targets of vaccine-induced immunity, traits underlying parasite virulence may also evolve. Previous experimental work in rodent malaria demonstrated that evolution in vaccinated hosts resulted in increased parasite virulence, as measured by anemia (minimum red blood cell density).
