The expression of Galectin-1 in endometrial adenocarcinoma was significantly different among tissues of different histological grades, pathological stages, degrees of myometrial infiltration, or lymph node metastasis (p > 0.05).
Together, our results demonstrate that RACK1 stimulates tumor invasion and lymph node metastasis of cervical cancer via galectin-1 and imply that targeting RACK1/galectin-1 axis provides promising means for cervical cancer treatment.
In a total of 107 human ovarian cancer tissues, higher Gal-1 expression strongly associated with higher histological grade, more lymph node metastases and more advanced FIGO stage, while lower E-cadherin expression strongly associated with higher histological grade, more lymph node metastases and more advanced FIGO stage.
We found that increased galectin-1 expression was associated with tumor size (odds ratio [OR] = 1.75; 95% confidence interval [CI]: 1.06-2.89; p = 0.029), clinical stage (OR = 3.89; 95% CI: 2.40-6.31; p < 0.001), and poorer differentiation (OR = 1.39; 95% CI: 1.14-1.69; p = 0.001), but not with age (OR = 1.07; 95% CI: 0.82-1.39; p = 0.597), sex (OR = 0.89; 95% CI: 0.74-1.07; p = 0.202), or lymph node metastasis (OR = 2.57; 95% CI: 0.98-6.78; p = 0.056).
LGALS1 was observed to be upregulated in highly invasive oral cancer cells, and elevated LGALS1 expression was correlated with cancer progression and lymph node metastasis in oral cancer tissue specimens.
Finally, a retrospective study revealed that galectin-1 levels in blood circulation negatively correlates with overall survival and positively correlates with lymph node metastasis of the patients.
Galectin-1 expression was highest in poorly differentiated pancreatic cancer cells and lowest in well-differentiated pancreatic cancer cells and was associated with tumor size, lymph node metastasis, differentiation, and UICC stage.
This study investigated the levels of galectin proteins and mRNA expression in a large cohort of patients with papillary thyroid carcinoma and matched lymph node metastases with particular emphasis on galectin-1 and galectin-3.
Galectin 1 expression was significantly correlated with the depth of invasion in the cervix (P=.015) and lymph node metastasis (P=.045) on univariate analysis.
