Emerging Therapeutic Strategies for Hearing Loss

Advanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production [PDF]

Journal of Neuroimmunology 174(1-2): 39-51 (2006), 2007
In the present study, we show that ascorbic acid dose-dependently inhibited interleukin-1beta (IL-1beta)-mediated PGE2 synthesis in the human neuronal cell line, SK-N-SH. Furthermore, in combination with aspirin, ascorbic acid augmented the inhibitory effect of aspirin on PGE2 synthesis. However, ascorbic acid had no synergistic effect along with other

Accelerated Bone Healing via Electrical Stimulation

Advanced Science, EarlyView.
Electrical stimulation significantly impacts bone healing by enhancing osteoblast proliferation, differentiation, and vascularization through calmodulin/calcineurin/NFAT signaling. It also boosts macrophage function and cell migration, presenting a comprehensive approach to accelerating bone repair.

Triene prostaglandins: prostacyclin and thromboxane biosynthesis and unique biological properties.

Proceedings of the National Academy of Sciences of the United States of America, 1979
Platelets enzymatically convert prostaglandin H(3) (PGH(3)) into thromboxane A(3). Both PGH(2) and thromboxane A(2) aggregate human platelet-rich plasma. In contrast, PGH(3) and thromboxane A(3) do not.

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

Advanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

Advanced Science, EarlyView.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

Update on peripheral mechanisms of pain: beyond prostaglandins and cytokines

Arthritis Research & Therapy, 2011
The peripheral nociceptor is an important target of pain therapy because many pathological conditions such as inflammation excite and sensitize peripheral nociceptors.

Misidentification of prostamides as prostaglandins

Journal of Lipid Research, 2005
Prostaglandins and endogenous cannabinoid metabolites share the same lipid backbone with differing polar head groups at exactly the position through which a large molecule is attached to provide antigenicity and thus raise antisera.

Regional distribution of the prostaglandin E2 receptor EP1 in the rat brain: accumulation in Purkinje cells of the cerebellum [PDF]

Journal of Molecular Neuroscience 27(3): 303-310 (2005), 2007
Prostaglandin E2 (PGE2), is a major prostanoid produced by the activity of cyclooxygenases (COX) in response to various physiological and pathological stimuli. PGE2 exerts its effects by activating four specific E-type prostanoid receptors (EP1, EP2, EP3, and EP4).

AhR‐Dependent Induction of β‐Defensin 1 in Colonic Epithelial Cells Regulates Cross‐Talk between Gut Microbiota and Immune Response Leading to Attenuation of Colitis

Advanced Science, EarlyView.
This study identifies a key signaling pathway involving the environmental sensor AhR and antimicrobial peptides, such as BD‐1, in the regulation of intestinal homeostasis. It highlights the role of BD‐1 in regulating gut microbiota and the intestinal immune response.
