Efecto del silenciamiento del gen WT-1 con ARNi en combinación con drogas anticancerígenas en modelo In vitro y en un modelo murino con metástasis a pulmón. por Thompson Armendáriz, Fernanda Guadalupe

“…In this work we investigated the potential of wt1 as a therapeutic target by exposing the murine melanoma line B16F10 to a complex of RNAi against wt1 (RNAi-wt1) in combination with chemotherapeutic drugs (Gemcitabine and Cisplatin), where a synergistic effect was determine by a isobologram; besides, a clonogenic test was performed, obtaining a decrease in the number of cell foci; in the PCR techniques a decrease in the expression of wt1 and the apoptotic gene bcl2 was observed; and in the cytometric test, a reduction in cell viability by apoptosis of 22% was found. …”

Biología de la latencia en semillas de chile piquín Capsicum annuum var. glabriusculum (Dunal) Heiser & Pickersgill. El papel de las fitohormonas. por López Valdez, Alma Paula

“…The results we got through the use of 3 types of bioassays (germination, phytohormone content and cell cycle) show that it is at 9 months of storage when the seed performs better at germination, this result could be verified with the data gotten with the use of HPLC because it was at this age when we observed a higher amount of gibberellins, auxins and kinetine and the flow cytometer analysis showed that at 9 months of age the seed shows higher cell division, these results let us conclude that at 9 months of age the seed has reached physiological maturity, reflected on the high content of phytohormones that promote germinationand the process of cell división that is very active at this age, therefore we suggest that at 9 months of seed storage is the ideal age to cultivate the seed and get higher percentage of germination.…”
