A Couple Of Straight Forward Strategies For The Thalidomide Totally Exposed
For the migration (5 �� 103) and invasion (1 �� 104) assays, cells were suspended in 400 ��L of DMEM containing 10% FBS, then seeded into the upper chamber; 600?��L of DMEM containing 10% FBS was added to the outside of the chamber. selleck compound After being cultured at 37��C under 5% CO2/95% air for 24 hours, the cells on the upper surface of the membrane were removed with a cotton-tipped applicator, and the migratory cells on the lower membrane surface were fixed with methanol and stained with Giemsa (Sigma-Aldrich, Munich, Germany). Cell migration was evaluated by counting the number of FaDu vehicle, SCC4 vehicle, FaDu/Rap-1A, and SCC4/Rap-1A mixed-stable clone cells that had migrated by 200�� phase-contrast microscopy on three independent membranes, then normalized against the vehicle cells to determine the relative ratio. For the invasion assays, 80 ��g/mL of Matrigel (BD Biosciences, San Jose, CA) were added to the upper surface of the membrane and allowed to gel at 37��C overnight. Then 1 �� 105 cells in 400 ��L of DMEM containing 10% FBS was seeded into the upper chamber, whereas 600 ��L of DMEM containing 10% FBS was added to the outside of the chamber. The rest of the protocol was the same as that see more for the migration assays. Vehicle-/HA-Rap-1A-/negative control-/siRap-1A- transfectants were used in the ��wound healing�� assay to test the alteration of cell migration. Cells were initially seeded uniformly onto 60-mm culture plates with an artificial ��wound�� carefully created at 0 hours. A P-10 pipette tip was used to scratch the subconfluent cell monolayer. Microphotographs were taken at 0 and 24 hours. Quantitative analysis of the percentage of wound healing was calculated using the distance across the wound at 0 and 24 hours, divided by the?distance measured at 0 hours for each cell line. Several clinicopathologic factors were evaluated, including sex, age (60 years), T1, T2 versus T3, T4 stage, N status, and TNM stage. Fisher's exact test was used?to evaluate the correlation between the clinicopathologic variables and the expression of Rap-1A.
