Lymphomas develop and progress in a specialized tissue microenvironment such as bone marrow as well as secondary lymphoid organs such as lymph node and spleen. The lymphoma microenvironment is characterized by a heterogeneous population of stromal cells, including fibroblastic reticular cells, nurse-like cells, mesenchymal stem cells, follicular dendritic cells, and inflammatory cells such as macrophages, T- and B-cells. These cell populations interact with the lymphoma cells to promote lymphoma growth, survival and drug resistance through multiple mechanisms. Angiogenesis is also recognized as an important factor associated with lymphoma progression. In recent years, we have learned that the interaction between the malignant and non-malignant cells is bidirectional and resembles, at least in part, the pattern seen between non-neoplastic lymphoid cells and the normal microenvironment of lymphoid organs. A summary of the current knowledge of lymphoma microenvironment focusing on the cellular components will be reviewed here.

Chemotherapy is widely used to treat lung adenocarcinoma (LUAD) patients comprehensively. Considering the limitations of chemotherapy due to drug resistance and other issues, it is crucial to explore the impact of chemotherapy and immunotherapy on these aspects. In this study, tumor samples from nine LUAD patients, of which four only received surgery and five received neoadjuvant chemotherapy, were subjected to scRNA-seq analysis.

Endocytosis is an essential cellular process that uptakes substances into cells at the plasma membrane from the extracellular space and plays a major role in plant development and responses to environmental stimuli. Research has shown that plant membrane-resident proteins are endocytosed and transported into plant endosomes in response to pathogen-secreted elicitors. However, there is no conclusive experimental evidence demonstrating how secreted cytoplasmic effectors from oomycetes and fungi enter host cells during infection.

Transcriptional regulation allows cells to execute developmental programs, maintain homeostasis, and respond to intra- and extracellular signals. Central to these processes are promoters, which in eukaryotes are sequences upstream of genes that bind transcription factors (TFs) and which recruit RNA polymerase to initiate mRNA synthesis. Valuable tools for studying promoters include reporter genes, which can be used to indicate when and where genes are activated.

This study aimed to investigate the expression, prognostic significance, methylation, and immune invasion levels of secreted frizzled-related proteins (SFRP1-5) in colorectal cancer (CRC). Additionally, the relationship between SFRP1/2 methylation and immune infiltration in CRC was explored. The expression of SFRP1-5 was analyzed using several databases, including GEO, TCGA, TIMER, STRING, and GEPIA.
