RNA tomography or tomo-seq combines mRNA sequencing and cryo-sectioning to spatially resolve gene expression. We have adapted this method for the nematode to generate anteroposterior gene expression maps at near-cellular resolution. Here, we provide a detailed overview of the method and present two approaches: one that includes RNA isolation for maximum sensitivity and one that is suitable for partial automatization and is therefore less time-consuming. For complete details on the use and execution of this protocol, please refer to Ebbing et al. (2018).

Irisin reshapes bone metabolic homeostasis to delay age-related osteoporosis by regulating the multipotent differentiation of BMSCs via Wnt pathway.
Front Mol Biosci

Introduction: Bone aging is linked to changes in the lineage differentiation of bone marrow stem cells (BMSCs), which show a heightened tendency to differentiate into adipocytes instead of osteoblasts. The therapeutic potential of irisin in addressing age-related diseases has garnered significant attention. More significantly, irisin has the capacity to enhance bone mass recovery and sustain overall bone health.

Aim: To investigate the involvement of low-density lipoprotein receptor-related protein 5 (LRP5) in inflammation and alveolar bone loss in periodontitis.
Materials And Methods: Gingival tissues were obtained from 10 periodontitis patients and 10 healthy individuals. Wild-type (WT) and osteoblast-specific Lrp5 conditional knock-out C57BL/6 (LRP5fl/fl;Oc-Cre) mice were used to establish a ligature-induced mouse model of periodontitis.
Diagnostic Value of Serum miR-499a-5p in Chinese Children with Autism Spectrum Disorders.

Department II of Acupuncture and Moxibustion, Dongzhimen Hospital Beijing University of Chinese Medicine, No. 116, Cuiping West Road, Tongzhou District, Beijing, 101121, China.
The purpose of this study was to investigate the expression of miR-499a-5p in children with autism spectrum disorders (ASD) and its value in early diagnosis of ASD. This is a retrospective case-control study that included 40 children with ASD as a case group and 43 healthy children as a control group. Magnetic resonance imaging (MRI) was performed on all subjects, and the children were scored with childhood autism rating scale (CARS) and autism behavior checklist (ABC).

Background: Age is the principal risk factor for neurodegeneration in both the retina and brain. The retina and brain share many biological properties; thus, insights into retinal aging and degeneration may shed light onto similar processes in the brain. Genetic makeup strongly influences susceptibility to age-related retinal disease.

Introduction: Malignant pleural effusion (MPE) is associated with poor quality of life and mortality in patients with tumors. In clinical practice, we observed that patients with malignant pleural effusion (MPE) and concurrent heart disease exhibited a decrease in MPE volumes following treatment with β-receptor blockers for heart disease. Immunosuppressive tumor microenvironment was found to play a substantial role in the progression of MPE, and mainly attributed to tumor-associated macrophages (TAMs).
