TRAF3/STAT6 axis regulates macrophage polarization and tumor progression.

Converting tumor-associated macrophages (TAMs) from the M2 to the M1 phenotype is considered an effective strategy for cancer therapy. TRAF3 is known to regulate NF-κB signaling. However, the role of TRAF3 in TAM polarization has not yet been completely elucidated.

TRK-fused gene (TFG) regulates ULK1 stability via TRAF3-mediated ubiquitination and protects macrophages from LPS-induced pyroptosis.

TRK-fused gene (TFG) is known to be involved in protein secretion and plays essential roles in an antiviral innate immune response. However, its function in LPS-induced inflammation and pyroptotic cell death is still unknown. Here, we reported that TFG promotes the stabilization of Unc-51 like autophagy activating kinase (ULK1) and participates in LPS plus nigericin (Ng) induced pyroptotic cell death.

Protein Tyrosine Kinase 7 Regulates EGFR/Akt Signaling Pathway and Correlates With Malignant Progression in Triple-Negative Breast Cancer.

Purpose: Triple-negative breast cancer (TNBC), the most aggressive subtype of breast cancer, is associated with high invasiveness, high metastatic occurrence and poor prognosis. Protein tyrosine kinase 7 (PTK7) plays an important role in multiple cancers. However, the role of PTK7 in TNBC has not been well addressed.

Overexpression of YB1 C-terminal domain inhibits proliferation, angiogenesis and tumorigenicity in a SK-BR-3 breast cancer xenograft mouse model.

Y-box-binding protein 1 (YB1) is a multifunctional transcription factor with vital roles in proliferation, differentiation and apoptosis. In this study, we have examined the role of its C-terminal domain (YB1 CTD) in proliferation, angiogenesis and tumorigenicity in breast cancer. Breast cancer cell line SK-BR-3 was infected with GFP-tagged YB1 CTD adenovirus expression vector.

Krüppel-like factor 4 induces apoptosis and inhibits tumorigenic progression in SK-BR-3 breast cancer cells.

Krüppel-like factor 4 (KLF4) functions as either a tumor suppressor or an oncogene in different tissues by regulating the expression of various genes. The aim of this study was to reveal the functions of KLF4 in regulating breast cancer apoptosis, proliferation, and tumorigenic progression. KLF4 expression levels in breast cancer tissues and breast cancer cell lines were found to be much lower than those in nontumorous tissues and a nontransformed mammary epithelial cell line.

[Expressions of immunogenic molecules in low-dose radiotherapy-treated human renal clear cell carcinoma 786-0 cells].

Objective: To explore the effects of low-dose radiation on the expression of immunogenic membrane molecules calreticulin (CRT) and MHC-I/II on the surface of human renal clear cell carcinoma 786-0 cells.

Methods: The inhibitory activity of low-dose radiation on cell line 786-0 was examined by CCK-8 assay. And the post-radiation membrane expressions of CRT, MHC-I and MHC-II were measured by flow cytometry while CRT was visualized by immunofluorescence photography.

Effective adoptive transfer of haploidentical tumor-specific T cells in B16-melanoma bearing mice.

Background: Adoptive transfer of allogeneic tumor-specific T cells often results in severe graft-versus-host disease (GVHD). Here, we sought to maximize graft-versus-tumor and minimize GVHD by using haploidentical T cells in pre-irradiated B16-melanoma bearing mice.

Methods: C57BL/6 mice bearing B16-melanoma tumors were irradiated with 0, 5, or 7 Gy total body irradiation (TBI), or 7 Gy TBI plus bone marrow transplantation.

[Expression of SM22α and its relationship with lymph node metastasis in breast cancer].

Objective: to analyze the relationship between the expression of SM22α and the lymph node (LN) metastasis of breast cancer and to investigate its molecular mechanisms.

Methods: reverse transcription-polymerase chain reaction (RT-PCR) was performed to detect the expression of SM22α in breast cancer tissue and adjacent normal breast tissue. RT-PCR and Western blot were employed to investigate the SM22α mRNA and protein level in tissues of breast fibroadenoma, breast cancer without LN metastasis and breast cancer with LN metastasis.
