[Gardner syndrome with chronic osteomyelitis of the jaw: a case report].

Gardner syndrome is a rare autosomal dominant disease. Its symptoms include multiple intestinal polyps, soft tissue tumors, dental disorders, osteoma, and congenital hypertrophy of the retinal pigment epithelium. Here, we present a patient with Gardner syndrome and chronic osteomyelitis of the jaw to highlight the serious damage that can be caused by Gardner syndrome.

Serine-arginine protein kinase 1 is associated with breast cancer progression and poor patient survival.

Breast cancer is the most common cancer and the second leading cause of mortality for women worldwide. It is necessary to identify valuable molecular markers to predict breast cancer progression in patients and treatment effect. Serine-arginine protein kinase 1 (SRPK1), a member of SR kinase family, phosphorylates the SR splicing factors which plays essential roles in normal cell development and multiple human diseases. In the current study, we wanted to explore if there are any relationships between SRPK1 expression in breast cancer and its clinical characteristics. The results showed that SRPK1 is upregulated in breast cancer cell lines and tissues at both mRNA and protein levels, measured by quantitative reverse transcriptase PCR and Western blotting. Immunohistochemical analysis showed a high expression of SRPK1 in 132 paraffin samples of patients with breast cancer; statistical analyses demonstrated that high expression of SRPK1 significantly correlated with clinical staging of patients with breast cancer (P < 0.001), TNM classification (P < 0.05). Low expression of SRPK1 leads to longer survival time, while high expression of SRPK1 leads to shorter survival time of patients. Multivariate analysis revealed that upregulation of SRPK1 might be an independent prognostic marker for the outcomes of patients with breast cancer. In conclusion, upregulation of SRPK1 might play an important role in the progression of breast cancer and might be considered as the potential diagnostic and therapeutic target to this malignancy.
