The atypical proteome of mitochondria from mature pollen grains.

Curr Biol

January 2025

Department of Plant Physiology, UPSC, Umeå University, 90187 Umeå, Sweden. Electronic address:

To propagate their genetic material, flowering plants rely on the production of large amounts of pollen grains that are capable of germinating on a compatible stigma. Pollen germination and pollen tube growth are thought to be extremely energy-demanding processes. This raises the question of whether mitochondria from pollen grains are specifically tuned to support this developmental process.

The Insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) gene is closely associated with the diseases, fat deposition, and growth and reproduction traits in animals. Investigations into the relationship between the IGF2BP2 gene polymorphism and growth and reproduction traits provide valuable breeding information for enhancing productivity and economic gains in pigeon. In this study, the single nucleotide polymorphisms (SNPs) in 13 exons and the 3' untranslated region (3'UTR) of the IGF2BP2 gene in 292 female pigeons Tianxiang 1 strain were detected through Sanger sequencing, and their association with pigeons' growth and reproduction traits were explored.

Glaucoma is an irreversible, progressive, degenerative eye disorder arising because of increased intraocular pressure, resulting in eventual vision loss if untreated. The QSPR relates, mathematically, by employing various algorithms, a specified property of a molecule that arises either from physical, chemical, or biological phenomena using various aspects of its structure. Here in, a similar application based on topological indices and inferences derived from the structure for the calculation of different drug properties like molar refractivity, refractive index, enthalpy, boiling points, molecular weight, and polarizability is presented.

Bioorg Chem

January 2025

Department of Pharmaceutical Chemistry, Manipal College of Pharmaceutical Sciences, Manipal, Academy of Higher Education, Manipal, Karnataka 576104, India.

Fragment-Based Drug Discovery (FBDD) has revolutionized drug discovery by overcoming the challenges of traditional methods like combinatorial chemistry and high-throughput screening (HTS). Leveraging small, low-molecular-weight fragments, FBDD achieves higher hit rates, reduced screening costs, and faster development timelines for clinically relevant drug candidates. This review explores FBDD's core principles, innovative methodologies, and its success in targeting diverse protein classes, including previously "undruggable" targets.

In recent years, metabolite identification of chemical constituents of traditional Chinese medicine (TCM) has been extensively studied. However, due to the intricacy of metabolic processes and the low concentration of metabolites, identifying metabolites of TCM in vivo is still a tough work. Meanwhile, credibility of metabolite identification through mass spectrum technology has been called into question by reason of the lack of metabolite standards.

College of Water Sciences, Beijing Normal University, Beijing 100875, PR China; Engineering Research Center of Groundwater Pollution Control and Remediation, Ministry of Education, Beijing Normal University, Beijing 100875, PR China. Electronic address:

The limited understanding of microbial response mechanism remains as a bottleneck to evaluate the long-term remediation effectiveness of in situ chemical oxidation in contaminated groundwater. In this study, we investigated long-term response of bacterial communities throughout five remediation stages of pre-oxidation, early-oxidation, late-oxidation, early-recovery and late-recovery. By analyzing bacterial biomass, taxa, diversity and metabolic functions, this work identified the consistently suppressed glyceraldehyde-3-phosphate dehydrogenase pathway and the enrichment of naphthalene degradation pathways for secondary products, suggesting persistent oxidation stress and enhanced microbial utilization of lower-molecular weight carbon sources at the oxidation and early-recovery stages.

Natural Source Zone Deletion (NSZD) is a viable long-term management option for sites impacted by petroleum hydrocarbon fuels. NSZD rate estimation methods for petroleum mass losses often use soil gas gradients of oxygen, carbon dioxide, methane or vapour concentrations through the vadose zone. Seeking greater efficiencies, we investigated if existing short-screened wells are reliable for representative sampling of soil gases in a vadose zone undergoing NSZD.

Department of Pediatrics, Division of Neonatology, Loma Linda University School of Medicine, Loma Linda, CA, USA; Lawrence D. Longo, MD Center for Perinatal Biology, Loma Linda University School of Medicine, Loma Linda, CA, USA. Electronic address:

Repeated use of nitroglycerin results in a loss of its vasodilatory efficacy which limits its clinical use for the treatment of angina pectoris. This tolerance phenomenon is a defining characteristic of all compounds classified as nitrodilators, which includes NTG as well as S-nitrosothiols and dinitrosyl iron complexes. These compounds vasodilate via activation of soluble guanylate cyclase, although they do not release requisite amounts of free nitric oxide (NO) and some do not even cross the plasma membrane.

The condition in which the insulin secretory ability of pancreatic β-cells decreases in diabetes is extremely important, but there are currently no biomarkers that reflect pancreatic β-cell failure. Therefore, we conducted a search for biomarkers, using pancreatic β-cell-specific 3-Phosphoinositide-dependent protein kinase 1 (PDK1) knockout mice, which develop severe hyperglycemia due to a decrease in pancreatic β-cell mass without insulin resistance. The analysis was performed in young mice when metabolic abnormalities were not yet apparent.
