First of all, WGCNA was used to analyse 9451 genes with significant changes in TB patients' whole blood. The 220 interferon-γ-related genes were identified, and then 30 key genes were screened using Cytoscape.

MLL3 suppresses tumorigenesis through regulating TNS3 enhancer activity.

MLL3 is a histone H3K4 methyltransferase that is frequently mutated in cancer, but the underlying molecular mechanisms remain elusive. Here, we found that MLL3 depletion by CRISPR/sgRNA significantly enhanced cell migration, but did not elevate the proliferation rate of cancer cells. Through RNA-Seq and ChIP-Seq approaches, we identified TNS3 as the potential target gene for MLL3.

Association of maximum standardized uptake value with occult mediastinal lymph node metastases in cN0 non-small cell lung cancer.

Objectives: The management of non-small cell lung cancer (NSCLC) relies on the tumour-node-metastasis (TNM) stage, and the treatment regimen differs based on the N status.

We explored predictors to identify false-negative N2 disease in PET-CT.

Global histone modification profiling reveals the epigenomic dynamics during malignant transformation in a four-stage breast cancer model.

But the key epigenomic events in cancer cell transformation still remain poorly understood.

The selective activation of p53 target genes regulated by SMYD2 in BIX-01294 induced autophagy-related cell death.

However, the detailed mechanisms of autophagy regulated by nuclear factors remain elusive.

Differential transcriptional response in macrophages infected with cell wall deficient versus normal Mycobacterium Tuberculosis.

Host-pathogen interactions determine the outcome following infection by mycobacterium tuberculosis (Mtb). Under adverse circumstances, normal Mtb can form cell-wall deficient (CWD) variants within macrophages, which have been considered an adaptive strategy for facilitating bacterial survival inside macrophages. However, the molecular mechanism by which infection of macrophages with different phenotypic Mtb elicits distinct responses of macrophages is not fully understood.

Dihydroartemisinin: a new story of an old drug against Schistosoma mansoni infection.

Currently, praziquantel is the drug of choice for the treatment of human Schistosoma mansoni infections. It has not been proved until now that there is real praziquantel resistance, but there is decreased praziquantel sensitivity. A search for novel antischistosomal agents against the parasite has been given a high priority.
