Photosymbiosis shaped animal genome architecture and gene evolution as revealed in giant clams.

Symbioses are major drivers of organismal diversification and phenotypic innovation. However, how long-term symbioses shape whole genome evolution in metazoans is still underexplored. Here, we use a giant clam (Tridacna maxima) genome to demonstrate how symbiosis has left complex signatures in an animal's genome.

Metabolic reprogramming induced by PSMA4 overexpression facilitates bortezomib resistance in multiple myeloma.

Multiple myeloma(MM) remains incurable with high relapse and chemoresistance rates. Differentially expressed genes(DEGs) between newly diagnosed myeloma and secondary plasma cell leukemia(sPCL) were subjected to a weighted gene co-expression network analysis(WGCNA). Drug resistant myeloma cell lines were established.

Glycosylation gene expression profiles enable prognosis prediction for colorectal cancer.

This study developed a prognostic model for patients with colon adenocarcinoma (COAD) based on glycosylation-associated genes. By analyzing TCGA-COAD data, 110 key genes were identified, and a prognostic model incorporating five glycosylation-related genes was constructed. The model exhibits good predictive performance and is significantly associated with clinical features such as age, N stage, M stage, and lymph node count.

Earthworm inspired lubricant self-pumping hydrogel with sustained lubricity at high loading.

The development of mechanically robust super-lubrication hydrogel materials with sustained lubricity at high contact pressures is challenging. In this work, inspired by the durable lubricity feature of the earthworm epidermis, a multilevel structural super-lubrication hydrogel (MS-SLH) system, the so-called lubricant self-pumping hydrogel, is developed. The MS-SLH system is manufactured by chemically dissociating a double network hydrogel to generate robust and wrinkled lubrication layer, and then laser etching was used to generate cylindrical texture pores as gland-like pockets for storing lubricants.

Role of hepatocyte-specific FOXO1 in hepatic glucolipid metabolic disorders induced by perfluorooctane sulfonate.

Perfluorooctane sulfonate (PFOS), a prevalent perfluoroalkyl substance (PFAS), is widely present in various environmental media, animals, and even human bodies. It primarily accumulates in the liver, contributing to the disruption of hepatic metabolic homeostasis. However, the precise mechanism underlying PFOS-induced hepatic glucolipid metabolic disorders remains elusive.
