Expression and clinical significance of interleukin-6 pathway in cholangiocarcinoma.

Background: Cholangiocarcinoma (CCA) is a typical inflammation-induced malignancy, and elevated serum interleukin-6 (IL-6) levels have been reported to be linked to the onset and progression of CCA. We aim to investigate the potential prognostic value of the IL-6 pathway for CCA.

Methods: We detected the expressions of IL-6, IL-6R, glycoprotein (gp130), C-reactive protein (CRP), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) in CCA tissue microarray using multiplex immunofluorescence.

Depletion of HIV reservoir by activation of ISR signaling in resting CD4T cells.

HIV reservoirs are extremely stable and pose a tremendous challenge to clear HIV infection. Here, we demonstrate that activation of ISR/ATF4 signaling reverses HIV latency, which also selectively eliminates HIV+ cells in primary CD4T cell model of latency without effect on HIV-negative CD4T cells. The reduction of HIV+ cells is associated with apoptosis enhancement, but surprisingly is largely seen in HIV-infected cells in which gag-pol RNA transcripts are detected in HIV RNA-induced ATF4/IFIT signaling.

Morphological, Phaneroptic, Habitat and Population Description of Three Muntjac Species in a Tibetan Nature Reserve.

Researchers have proposed a variety of classification schemes for the species in the genus (Artiodactyla: Cervidae) based on morphological, molecular, and other evidence, but disputes remain. The Tibetan Yarlung Zangbo Grand Canyon National Nature Reserve in the Eastern Himalayas is an area with a rich diversity of muntjac species. The habitats of many species overlap in this area, but systematic research in this area is lacking.

Crotonylation sensitizes IAPi-induced disruption of latent HIV by enhancing p100 cleavage into p52.

The eradication of HIV infection is difficult to achieve because of stable viral reservoirs. Here, we show that crotonylation enhances AZD5582-induced noncanonical NF-κB (ncNF-κB) signaling, further augmenting HIV latency reversal in Jurkat and U1 cell line models of latency, HIV latently infected primary CD4+ T cells and resting CD4+ T cells isolated from people living with HIV. Crotonylation upregulated the levels of the active p52 subunit of NF-κB following AZD5582.

GATA6 promotes epithelial-mesenchymal transition and metastasis through MUC1/β-catenin pathway in cholangiocarcinoma.

GATA6 acts as an oncogene or tumour suppressor in different cancers. Previously, we found that aberrant expression of GATA6 promoted metastasis in cholangiocarcinoma (CCA). However, the mechanism by which GATA6 promotes metastasis in CCA is unclear.

Impact of body mass index on postoperative outcomes in patients undergoing radical resection for hilar cholangiocarcinoma.

Complex Interactions between Cohesin and CTCF in Regulation of Kaposi's Sarcoma-Associated Herpesvirus Lytic Transcription.

CTCF and the cohesin complex modify chromatin by binding to DNA and interacting with each other and with other cellular proteins. Both proteins regulate transcription by a variety of local effects on transcription and by long-range topological effects. CTCF and cohesin also bind to herpesvirus genomes at specific sites and regulate viral transcription during latent and lytic cycles of replication.

The interaction of LOXL2 with GATA6 induces VEGFA expression and angiogenesis in cholangiocarcinoma.

Cholangiocarcinoma (CCA) is the second most common hepatobiliary cancer after hepatocellular carcinoma. Antiangiogenic therapy has been administered to patients with CCA, but the benefits of this therapy remain unsatisfactory. Improved understanding of the molecular mechanisms underlying angiogenesis in CCA is required.

Deep latency: A new insight into a functional HIV cure.

Latent HIV reservoir is the main obstacle that prevents a cure for HIV-1 (HIV). While antiretroviral therapy is effective in controlling viral replication, it cannot eliminate latent HIV reservoirs in patients. Several strategies have been proposed to combat HIV latency, including bone marrow transplantation to replace blood cells with CCR5-mutated stem cells, gene editing to disrupt the HIV genome, and "Shock and Kill" to reactivate latent HIV followed by an immune clearance.
