Background: Intervertebral disc degeneration (IVDD) is the leading cause of low back pain, and repair using nucleus pulposus-derived mesenchymal stem cells (NP-MSCs) represents a promising therapeutic approach. However, both endogenous and transplanted NP-MSCs demonstrate limited proliferative capacity, increased apoptosis, and reduced resilience to the harsh microenvironment within the degenerative intervertebral disc (IVD).
Methods: RNA sequencing (RNA-seq) was utilized to identify genes and associated mechanisms that mediate the responses of NP-MSCs to acidic conditions.
Artificial nanofluidic devices inspired bylight-driven ion transport in biological systems, leveraging the photoelectric effect, have attracted extensive attention for their potential in signal transduction and smart ion transport applications. However, effective separation of photogenerated carriers in traditional p-n junction interface can be hindered by energy band structure of different semiconductor materials. Here, we present a novel approach using conductive polypyrrole (PPy) to modify graphene oxide (GO), creating polypyrrole-graphene oxide (PyGO) functional lamellar conductive nanochannels with tailored channel-sized gradients and inherent optical-electrical coupling sensitivity via a facile super-assembly strategy.

Consistent activation of Signal Transducer and Activator of Transcription 3 (STAT3) in epidermal keratinocyte transactivates various keratinocyte-derived pro-inflammatory cytokines and elicits spontaneous psoriasis-like skin inflammation. In the current study, we first report that topical application of protocatechuic aldehyde (PA), the bioactive compound from Salvia miltiorrhiza (Danshen), significantly improved psoriasis-like skin symptoms and reduced immune cell infiltration in psoriatic lesions.

However, the molecular mechanisms underlying colorectal adenoma carcinogenesis remain largely unknown. Here, we analyzed transcriptomic profile changes in normal, advanced adenoma, and carcinoma tissues from patients with CRC, revealing that glutamic-pyruvic transaminase 1 () in colorectal tissues was down-regulated during the N-A-C process and correlated with poor CRC prognosis.

Exopolysaccharides (EPS) from probiotic bacteria have been shown to regulate microbial composition and metabolism, but their role in promoting probiotic growth and alleviating inflammation in UC remains unclear. Here, we investigate BLEPS-1, a novel EPS derived from Bifidobacterium longum subsp.

In this study, a covalent-organic framework (COF)-based artificial photosynthesis system is realized through the co-assembly of adenosine triphosphate (ATP) synthase and a light-responsive proton generator onto an imine-based COF, RT-COF-1. This system demonstrates an ATP production rate of 0.

A key feature of OSA is the upregulation and stabilization of hypoxia-inducible factor 1 (HIF-1), a crucial metabolic regulator that facilitates rapid adaptation to changes in oxygen availability. Adenosine A2A receptor (A2AR), a major adenosine receptor, regulates HIF-1 under hypoxic conditions, exerting anti-inflammatory properties and affecting lipid metabolism.

A total of 495 patients age 18-75 years with stage Ⅱ-Ⅲ rectal cancer were randomly assigned to three treatment arms: fluorouracil plus radiotherapy, mFOLFOX6 plus radiotherapy, or mFOLFOX6 alone, followed by surgery and adjuvant chemotherapy. With a median follow-up of 10 years, the 10-year disease-free survival (DFS) rates were 52.

The current approach to treating inflammatory bowel disease (IBD) primarily focuses on managing inflammation rather than maintaining the integrity of the intestinal barrier. In our study, we sought to investigate the potential role of PHLDA1 in preserving intestinal barrier function as a promising strategy for treating IBD. We observed a significant decrease in PHLDA1 expression in intestinal epithelial cells (IECs) of both IBD patients and mice with chemically induced colitis.

Oxidative cross-dehydrogenative C-H/C-H functionalizations represent an exemplary approach for synthesizing carbonyl compounds via α-heteroarylation. Here we present the development of a direct anodic oxidative coupling process between 2-acylimidazoles and divergent heterocyclic systems including indole, pyrrole, and furan, facilitated by ferrocene-assisted asymmetric nickel electrocatalysis with high levels of enantioselectivity. Mechanistic investigations indicate that the reaction initially involves the formation of a chiral Ni-bound α-carbonyl radical, which is then captured by the heteroarene radical cation via intermolecular stereoselective radical/radical cation coupling.
