Nerve-Derived Extracellular Matrix Promotes Neural Differentiation of Bone Marrow Stromal Cells and Enhances Interleukin-4 Efficacy for Advanced Nerve Regeneration.

Facilitating neuronal differentiation of stem cells and microenvironment remodeling are the key challenges in cell-based transplantation strategies for central nervous system regeneration. Herein, the study harnesses the intrinsic pro-neural differentiation potential of nerve-derived extracellular matrix (NDEM) and its specific affinity for cytokines to develop an NDEM-gelatin methacryloyl(gelMA)-based bifunctional hydrogel delivery system for stem cells and cytokines. This system promotes the neural differentiation of bone marrow stromal cells (BMSCs) and optimizes the therapeutic index of Interleukin-4 (IL-4) for spinal cord injury (SCI) treatment.

CXCL16 promotes proliferation of head and neck squamous cell carcinoma by regulating GPX1-mediated antioxidant levels.

Numerous studies have demonstrated that the high expression of CXC motif chemokine ligand 16 (CXCL16) in cancer correlates with poor prognosis, as well as tumor cell proliferation, migration, and invasion. While CXCL16 can serve as a tumor biomarker, the underlying mechanism in modulating head and neck squamous cell carcinoma (HNSCC) remains unclear. In this study, the aimed was to investigate the CXCL16 expression in HNSCC and to uncover the potential underlying mechanism.

Characterization of 3,3'-iminodipropionitrile (IDPN) damaged utricle transcriptome in the adult mouse utricle.

Utricle is an important vestibular sensory organ for maintaining balance. 3,3'-iminodipropionitrile (IDPN), a prototype nitrile toxin, has been reported to be neurotoxic and vestibulotoxic, and can be used to establish an damage model of vestibular dysfunction. However, the mechanism of utricular HCs damage caused by IDPN is unclear.

Random survival forest predicts survival in patients with metastatic laryngeal and hypopharyngeal cancer and the prognostic benefits of surgery and radiotherapy.

Laryngeal and hypopharyngeal cancers are prominent within head and neck malignancies. The diagnosis of distant metastasis (DM) invariably signals poor prognosis, underscoring the need to optimize current treatment approaches. Patient data for metastatic laryngeal and hypopharyngeal cancer were extracted from the SEER database (2000-2020).

Recent advances of photodiagnosis and treatment for head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma (HNSCC) are the most common type of head and neck tumor that severely threatens human health due to its highly aggressive nature and susceptibility to distant metastasis. The diagnosis of HNSCC currently relies on biopsy and histopathological examination of suspicious lesions. However, the early mucosal changes are subtle and difficult to detect by conventional oral examination.

Advances in Microfluidic Cochlea-On-A-Chip.

The current understanding of the human auditory system has been primarily based on studies using animal and cellular models. Organoids have been used to simulate cochlear structures and replicate cochlear functions. However, the physical and chemical cues required to control the development of cochlear organoids accurately remain poorly understood, limiting research advances on cochlea-on-a-chip systems.

Tumor-Targeted Magnetic Micelles for Magnetic Resonance Imaging, Drug Delivery, and Overcoming Multidrug Resistance.

Nasopharyngeal carcinoma (NPC) is prevalent in Southern China. Unfortunately, current treatments encounter multidrug resistance (MDR). Overexpression of P-glycoprotein (P-gp), resulting in the efflux of chemotherapy drugs, is one of the significant mechanisms causing MDR.

[Expert consensus on endoscopic surgery for the pediatric middle ear cholesteatoma based on the classification of cholesteatoma location].

Pediatric middle ear cholesteatoma is an aggressive keratotic lesion caused by abnormal proliferation of keratinised squamous epithelium in the temporal bone, with the characteristics of high postoperative recurrence rate, poor hearing effect and poor quality of life. Endoscopic surgery is able to deal with the majority of pediatric middle ear cholesteatoma cases with the features of minimal trauma and wide surgical field. However, endoscopic surgical treatment still has problems in standardization.

AAV-regulated overexpression promotes hair cell regeneration.

Inner ear hair cell (HC) damage is irreversible in mammals, but it has been shown that supporting cells (SCs) have the potential to differentiate into HCs. , a serine protease inhibitor, encodes protease nexin 1, and this has been suggested to be a factor that promotes HC regeneration. In this study, we overexpressed in inner ear SCs cultured in two- and three-dimensional systems using the adeno-associated virus-inner ear (AAV-ie) vector, which promoted organoid expansion and HC differentiation.

Revealing the causal role of immune cells in malignant neoplasms of the head and neck: insights from Mendelian randomization.

Background: Immune escape and immunosuppression play crucial roles in the onset and progression of head and neck malignant neoplasms (HNMN). However, previous studies on the relationship between immune cells and HNMN have yielded inconsistent results.

Methods: In this study, we performed bidirectional two-sample Mendelian randomisation (MR) analyses using genome-wide association study (GWAS) and FinnGen databases to examine the association between 731 immune cell features and the risk of HNMN.

Conditional Overexpression of Net1 Enhances the Trans-Differentiation of Lgr5 Progenitors into Hair Cells in the Neonatal Mouse Cochlea.

Sensorineural hearing loss is mainly caused by damage to hair cells (HC), which cannot be regenerated spontaneously in adult mammals once damaged. Cochlear Lgr5 progenitors are characterised by HC regeneration capacity in neonatal mice, and we previously screened several new genes that might induce HC regeneration from Lgr5 progenitors. Net1, a guanine nucleotide exchange factor, is one of the screened new genes and is particularly active in cancer cells and is involved in cell proliferation and differentiation.

Increased expression of epithelial-mesenchymal transition markers associated with recurrence of sinonasal inverted papilloma.

Sinonasal inverted papilloma (SNIP) is a benign epithelial proliferative disease with a high recurrence rate. The role of epithelial-mesenchymal transition (EMT) in the pathogenesis of SNIP remains unclear. EMT marker expression is elevated in SNIP tissues and is associated with its recurrence.

Molecular insights into the activation mechanism of GPR156 in maintaining auditory function.

The class C orphan G-protein-coupled receptor (GPCR) GPR156, which lacks the large extracellular region, plays a pivotal role in auditory function through G. Here, we firstly demonstrate that GPR156 with high constitutive activity is essential for maintaining auditory function, and further reveal the structural basis of the sustained role of GPR156. We present the cryo-EM structures of human apo GPR156 and the GPR156-G complex, unveiling a small extracellular region formed by extracellular loop 2 (ECL2) and the N-terminus.
