Wilson's disease (WD) is a hereditary condition marked by abnormalities in copper metabolism, which precipitate a spectrum of neurological symptoms and cognitive impairments. Emerging research has highlighted ferroptosis (FPT) as a distinct type of programmed cell death, potentially linked to various cognitive dysfunctions. Nevertheless, the connection between FPT and cognitive impairment in Wilson's disease (WDCI) remains largely enigmatic.

Article Synopsis
  • The study aims to analyze the recurrence patterns and survival rates of patients with HER2-low breast cancer compared to those with HER2-0 tumors.
  • Over 2000 patients were evaluated, revealing that HER2-0 patients had a higher risk of visceral recurrence, specifically in the lungs, while HER2-low patients faced increased local recurrence risks but lower risk of contralateral breast cancer.
  • Ultimately, the findings suggest that while recurrence patterns differ between the two groups, HER2-low breast cancer does not appear to represent a separate prognostic category.

Article Synopsis
  • - Huang-Pu-Tong-Qiao (HPTQ), a Traditional Chinese Medicine formula, shows significant promise in treating Alzheimer's disease by potentially reducing a process called pyroptosis, which is linked to the disease's progression.
  • - The study employed both network pharmacology and experiments on APP/PS1 mice and Aβ-injured HT22 cells to explore HPTQ's mechanisms, revealing that it positively affects memory and cell integrity while decreasing harmful protein expressions related to inflammation.
  • - Results suggest that HPTQ may exert its therapeutic effects by inhibiting the NLRP3 inflammasome, thus protecting neurons from pyroptosis, presenting it as a valuable candidate for Alzheimer's clinical treatment.

Conducting randomized controlled trials for medications targeting rare diseases presents significant challenges, due to the scarcity of participants and ethical considerations. Under such circumstances, leveraging real-world data (RWD) to generate supporting evidence may be accepted by the regulatory agency. Constructing an external control arm (ECA) from RWD for a single-arm trial has been conducted occasionally.

Background: Aloe-emodin (AE), a monomer derived from traditional Chinese medicine, has demonstrated remarkable efficacy in the clinical management of cognitive disorders. Ferroptosis (FPT), a specialized form of programmed cell death, plays a critical role in the pathological progression of various cognitive diseases.

Methods: This study explored the therapeutic potential of AE in a rat model of Wilson's disease cognitive impairments (WDCI) and examined whether these effects are mediated through the silencing information regulator 1 (SIRT1)-regulated FPT signaling pathway.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious pulmonary vascular disease characterized by residual thrombi in the pulmonary arteries and distal pulmonary microvascular remodeling. The pathogenesis of CTEPH remains unclear, but many factors such as inflammation, immunity, coagulation and angiogenesis may be involved. Monocytes are important immune cells that can differentiate into macrophages and dendritic cells and play an important role in thrombus formation.

Objective: Emerging evidence has shown that gut diseases can regulate the development and function of the immune, metabolic, and nervous systems through dynamic bidirectional communication on the brain-gut axis. However, the specific mechanism of intestinal diseases and vascular dementia (VD) remains unclear. We designed this study especially, to further clarify the connection between VD and inflammatory bowel disease (IBD) from bioinformatics analyses.

Unlabelled: Inflammatory breast cancer (IBC) is a highly aggressive subtype of breast cancer characterized by rapidly arising diffuse erythema and edema. Genomic studies have not identified consistent alterations and mechanisms that differentiate IBC from non-IBC tumors, suggesting that the microenvironment could be a potential driver of IBC phenotypes. Here, using single-cell RNA sequencing, multiplex staining, and serum analysis in patients with IBC, we identified enrichment of a subgroup of luminal progenitor (LP) cells containing high expression of the neurotropic cytokine pleiotrophin (PTN) in IBC tumors.

This study explores the impact of anthropogenic land use changes on the macroinvertebrate community structure in the streams of the Cangshan Mountains. Through field collections of macroinvertebrates, measurement of water environments, and delineation of riparian zone land use in eight streams, we analyzed the relationship between land use types, stream water environments, and macroinvertebrate diversities. The results demonstrate urban land use type and water temperature are the key environmental factors driving the differences in macroinvertebrate communities up-, mid-, and downstream.

Background: Lipid metabolism has been implicated in a variety of normal cellular processes and strongly related to the development of multiple diseases, including tumor. Tumor-associated macrophage (TAM) has emerged as a crucial regulator in tumorigenesis and promising target for tumor treatment.

Aim Of Review: A thorough understanding of TAM lipid metabolism and its value in tumorigenesis may provide new ideas for TAM-based anti-tumor therapy.

Pulmonary hypertension (PH) is a pathological disorder with multiple clinical manifestations that lead to cardiovascular and respiratory diseases in most patients. Recent studies have revealed that microRNAs (miRNAs) play important roles as upstream signaling molecules in several diseases, including PH. However, miRNAs that can be used as diagnostic or prognostic biomarkers for PH have not been identified.

Article Synopsis
  • The study investigates how Huangdi Anxiao Capsules (HDAX) can protect rat adrenal pheochromocytoma (PC12) cells from cognitive dysfunction caused by high glucose levels, focusing on the NLRP3-mediated pyroptosis mechanism.
  • PC12 cells were divided into several groups to assess the effects of HDAX and the NLRP3 inhibitor mcc950 on cell viability and pyroptosis indicators using various assays.
  • Results showed that the model group (high glucose) had reduced cell survival and increased inflammatory markers, while both HDAX and mcc950 treatments improved cell health and reduced markers of pyroptosis compared to the model group.

Background: Wilson's disease (WD), an autosomal recessive genetic disease, is characterized by copper metabolism disorder. WD patients may have a series of cognitive deficits in terms of neurological symptoms. Ferroptosis (FPT), a type of programmed cell death, is involved in the pathological progression of various cognitive disorders, and silent information regulator 1 (SIRT1) is considered to be a key factor in FPT.

Background: Acute myeloid leukaemia (AML) is characterised by the malignant accumulation of myeloid progenitors with a high recurrence rate after chemotherapy. Blasts (leukaemia cells) exhibit a complete myeloid differentiation hierarchy hiding a wide range of temporal information from initial to mature clones, including genesis, phenotypic transformation, and cell fate decisions, which might contribute to relapse in AML patients.

Methods: Based on the landscape of AML surface antigens generated by mass cytometry (CyTOF), we combined manifold analysis and principal curve-based trajectory inference algorithm to align myelocytes on a single-linear evolution axis by considering their phenotype continuum that correlated with differentiation order.

  • Hyperphosphorylation of Tau is a key factor in Alzheimer’s disease (AD) pathogenesis, making it essential to study the mechanisms behind this process.
  • The research involved rat AD models, revealing that lower phosphorylation of microtubule-associated protein 1A (MAP 1A) correlates with increased Tau hyperphosphorylation, with experiments confirming these findings in various AD models.
  • The study concluded that MAP 1A can protect neurons by altering its binding with cyclin-dependent kinase 5 (CDK5), decreasing Tau phosphorylation and promoting cell survival, thus offering insights into potential therapeutic strategies for AD.

The cohesin complex plays essential roles in chromosome segregation, 3D genome organisation, and DNA damage repair through its ability to modify DNA topology. In higher eukaryotes, meiotic chromosome function, and therefore fertility, requires cohesin complexes containing meiosis-specific kleisin subunits: REC8 and RAD21L in mammals and REC-8 and COH-3/4 in . How these complexes perform the multiple functions of cohesin during meiosis and whether this involves different modes of DNA binding or dynamic association with chromosomes is poorly understood.
