The role of receptor tyrosine kinase signalling in HER-2-positive cells and trastuzumab (Herceptin) resistance in breast cancer [PDF]

open access: yes, 2009
HER-2 gene amplification or overexpression occurs in approximately 25 % of breast cancers, and trastuzumab (Tmab) is a monoclonal antibody currently used to treat patients with HER-2-overexpressing breast cancer.

Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

open access: yesAdvanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

The modification of insulin to enhance oral delivery systems [PDF]

open access: yes, 2009
textWhile a number of PEGylated proteins have been studied for injectable applications and reviewers have used this data to speculate possible oral delivery improvements, a detailed investigation of PEGylated insulin for oral delivery and the development

Gonadotropin‐Inhibitory Hormone (GnIH) and Its Receptor GPR147 Mediates Acute Stress‐Induced Activation of the Locus Coeruleus‐SAM Axis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Gonadotropin‐inhibitory hormone (GnIH, also known as RFamide‐related peptide‐3, RFRP‐3) is a hypothalamic neuropeptide that regulates vertebrate reproduction via its receptor GPR147. Although GnIH is known to mediate stress‐induced reproductive suppression, its role in broader stress responses remains unclear.

Insulin and insulin receptor abnormality.

open access: yesNihon Naika Gakkai Zasshi, 1993
インスリンあるいはインスリン受容体の異常が糖尿病者で見い出された.インスリン受容体に結合しえない異常インスリンやプロインスリンが産生されるインスリン遺伝子の異常,細胞表面のインスリン受容体の数や機能が減少するインスリン受容体遺伝子の異常あるいはインスリン受容体に対する自己抗体の存在が報告されている.いずれも高インスリン血症の存在が診断への手掛りとなるが,インスリンの異常ではインスリン抵抗性は存在しないがインスリン受容体の異常では存在する点が最大の鑑別点となる.インスリン遺伝子あるいはインスリン受容体遺伝子の異常が見い出された家系について検討すると,糖尿病の発症年齢,重症度は均一でなく,その発症には他の遺伝子異常あるいは環境要因の関与も推定され,糖尿病の発症にはいくつかの因子が関与していると考えられた.

Quaternary Structure of the Insulin-Insulin Receptor Complex

open access: yes, 1999
The three-dimensional (3D) structure of the intrinsically dimeric insulin receptor bound to its ligand, insulin, was determined by electron cryomicroscopy. Gold-labeled insulin served to locate the insulin-binding domain. The 3D structure was then fitted

BAP31 Drives Cartilage Calcification through Disruption of Autophagosome–Lysosome Fusion in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31
