Unraveling the Role of MDK‐SDC4 Interaction in Pancreatic Cancer‐Associated New‐Onset Diabetes by Single‐Cell Transcriptomic Analysis

open access: yesAdvanced Science, EarlyView.
Midkine (MDK) is a mediator of the interaction between pancreatic cancer and beta cells. MDK, which originated from pancreatic ductal adenocarcinoma cells, exerted deleterious effects on paraneoplastic beta cells by binding to the SDC4 receptor on the beta cell surface and subsequently downregulating the Ras signaling pathway, thereby impairing insulin

Branched‐Chain α Keto‐Acid Dehydrogenase Kinase‐Mediated AKT Phosphorylation Promotes RCC Tumorigenesis and Drug Resistance

open access: yesAdvanced Science, EarlyView.
This study identifies a novel oncogenic role and a previously unrecognized phosphorylation substrate of BCKDK in RCC, wherein it promotes tumor progression and drug resistance through AKT phosphorylation at both Thr308 and Ser473 sites and activation of AKT/mTOR and AKT/ABCB1 signaling pathways, offering a promising prognostic marker and therapeutic ...

UCP2 Upregulates ACSL3 to Enhance Lipid Droplet Release from Acinar Cells and Modulates the Sirt1/Smad3 Pathway to Promote Macrophage‐to‐Myofibroblast Transition in Chronic Pancreatitis

open access: yesAdvanced Science, EarlyView.
These findings suggest that UCP2 promotes LD formation and release in acinar cells by upregulating ACSL3 expression. This alteration in the local lipid metabolic environment indirectly drives the MMT process. Additionally, UCP2 may regulate the acetylation of Smad3 through Sirt1, enhancing its nuclear activity and activating the TGF‐β/ Smad3 signaling ...

Maxillary first molar with two palatal roots: A case report

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2004
Background and Objective: One of the main reasons of root canal failure is missed canals. Maxillary first molar is one of the most investigated teeth for extra canals.

Cracking the Valence Code: Patterned Facial Kinematics and Neural Signatures of Emotional Expressions in Mice

open access: yesAdvanced Science, EarlyView.
An AI‐powered system decodes emotional valence from mouse facial expressions, identifying ear dynamics as key indicators. By integrating facial kinematics with synchronized neural recordings, this approach establishes a direct link between behavior and brain activity, advancing automated emotion recognition in animal models.
