The p21-activated kinases signal through a number of cellular pathways fundamental to growth, differentiation and apoptosis.
A wealth of information has accumulated at an impressive pace in the recent past, both with regard to previously identified
targets for p21-activated kinases that regulate the actin cytoskeleton and cellular stress pathways and with regard to newly
identified targets and their role in cancer. Emerging data also provide new clues towards a previously unappreciated link
between these various cellular processes. The present review attempts to provide a quick tutorial to the reader about the
evolving significance of p21-activated kinases and small GTPases in breast cancer, using information from mouse models, tissue
culture studies, and human materials. 相似文献

Background: Nuclear localization of cyclin B1 is an indicator for cells undergoing mitotic division, and the overexpression has shown promising results as a good prognostic predictor for patients of squamous cell carcinoma (SCC). Cyclin B1 overexpression among histological grades of conventional oral squamous cell carcinoma (COSCC), as well as comparison with verrucous carcinoma (VC) has been less investigated.
Study Design: Immunohistochemical expression of cyclin B1 was compared with various clinicopathological features in 30 primary COSCC and 31 primary VC cases.
Result: Cyclin B1 showed significant overexpression for some clinical features for both the variants of oral squamous cell carcinoma. In histopathological variants, statistical significance was observed among grades of COSCC, as well as COSCC and its grades with VC. The concomitant increase in cyclin B1 overexpression from VC to grades COSCC was observed.
Conclusion: Our study findings draw attention to cyclin B1 overexpression is involved in early carcinogenesis, cell differentiation and tumor proliferation.
Key words:Cyclin B1, oral squamous cell carcinoma, verrucous carcinoma, head and neck cancer. 相似文献

Objective: To assess the knowledge, attitude, and practice (KAP) regarding COVID-19 among COVID-19 patients and their relation with the outcomes.Methods: This cross-sectional study was carried out among COVID-19 patients (18-year-old or older) consecutively admitted to a dedicated COVID-19 hospital located in northwest Rajasthan, India. Data regarding socio-demographic parameters, KAP, and primary composite outcome (admission to intensive care unit, mechanical ventilation, or in-hospital death) were collected. KAP scores were compared between different demographic variables and primary composite outcomes. Association between different demographic variables, primary composite outcomes, and KAP scores were determined through multivariate linear regression. Besides, the correlation among KAP scores was analyzed. Results: Out of the total 222 patients, most of them (65.76%) had average KAP scores towards COVID-19. The mean scores for knowledge were 7.88, with an overall correct rate of 71.63%; the mean attitude scores were 2.42, with an overall correct rate of 60.50%; the mean practice scores were 5.12, with an overall correct rate of 64.00%. Patients who met the primary composite outcomes had higher knowledge scores, but lower attitude and practice scores. The result showed a significant positive correlation between the level of education, socioeconomic class, and knowledge, attitude, and practice towards COVID-19. Knowledge towards COVID-19 was significantly associated with a positive attitude and good practice. Conclusions: Our findings show that adult COVID-19 patients have average KAP towards COVID-19 among COVID-19 patients. Poor attitude and practice towards COVID-19 are associated with adverse outcomes, so it is suggested to strengthen attitude and practice towards COVID-19 to improve the outcomes. 相似文献
