[Q]: The movie begins in the year 1967 with a pregnant woman being admitted to a hospital, bleeding from the neck. Paramedics think she was attacked by some type of animal. Doctors perform an emergency C-Section, and her baby (a boy) is born alive just as she dies.Thirty years later a young man named Dennis (Kenny Johnson) is riding in a car with an attractive redhead named Racquel (Traci Lords) heading to an underground nightclub (located, oddly, in a slaughterhouse) somewhere in Los Angeles. After addressing the doorman in Russian, Racquel brings the young man into the club. The man is confused and trying to understand the rules of the club. Some of the regulars indifferently push him aside. Saying he needs a drink, the sprinkler suddenly system activates, raining blood down on everyone inside. It is then that he (and the audience) realizes that everyone in the club is a vampire.Dennis desperately tries to get away and winds up at the feet of a menacing figure in a black-leather trenchcoat. The vampires look on this figure with awe, mumbling the words: "it's the Daywalker!" This is our first look at Blade (Wesley Snipes), the vampire killer.Blade pulls out a shotgun and opens fire on the vampires, who instantly burn to ashes when killed. When the gun is knocked out of his hands by Racquel, Blade uses a set of silver stakes to kill Racquel and more vampires, including the disk jockey. Soon all the vamps are either dead or have fled except for one; a heavyset vamp named Quinn (Donal Logue), whom Blade has apparently run into before. Blade pins Quinn to the wall, and then sets him on fire before confronting the last member in the club (the human man from the beginning). Finding no vampire bite marks on Dennis, Blade lets him live and makes his escape as the police arrive.Quinn is extinguished and taken to the local hospital. A morgue technician examines his blood and shows the results to Dr. Karen Jenson (N'Bushe Wright), who finds a number of irregularities, including abnormally developed jaw muscles. As they are discussing the test results, Quinn springs back to life and bites both doctors. Before he can finish Dr. Jenson, Blade shows up and saves her, cutting off one of Quinn's arms.Blade brings Karen to his hideout and asks for help from his mentor, an elderly man named named Whistler (Kris Kristofferson). Whistler injects Dr. Jenson with a solution of garlic essence and silver nitrate and remarks that she has a 50/50 chance of recovering.Meanwhile, a group of vampires are discussing Blade's latest attack on their members. Apparently this club (and to an extent, Quinn) is the property of a vampire named Deacon Frost (Stephen Dorff). Frost wants the vampires to outright rule the humans and use them as a food source while the others (particularly an older vampire named Dragonetti) prefer to maintain a peaceful co-existance. Dragonetti (Udo Kier) in particular does not like Frost because Frost is not a "pure-blood" (ie: was not born a vampire, merely became one through the bite of another). Frost is also arrogant and his & the actions of his followers draw unnecessary attention to the vampire underworld.The next morning, Jenson awakens and sees Whistler injecting Blade with some type of serum. She tries to run away but Whistler confronts her and tells her that he and Blade are hunting vampires. Karen of course is skeptical, but Whistler goes on to talk about what they use to hunt- explaining that vampires are severely allergic to silver & garlic while also being vulnerable to sunlight (ultraviolet rays in particular). Whistler fuels up Blade's car and gives him a new UV flashlight to use when hunting that night. Whistler also gives Karen a type of "vampire mace" (garlic & silver nitrate in a liquid form).Blade drops Karen off at her apartment and she tries to pack up and get out of town. A police officer, identifying himself as Officer Krieger (Kevin Patrick Walls), arrives and questions her about the events

[Q]: GATA-1 and the ets factor PU.1 have been reported to functionally antagonize one another in the regulation of erythroid versus myeloid gene transcription and development. The CCAAT enhancer binding protein epsilon (C/EBPepsilon) is expressed as multiple isoforms and has been shown to be essential to myeloid (granulocyte) terminal differentiation. We have defined a novel synergistic, as opposed to antagonistic, combinatorial interaction between GATA-1 and PU.1, and a unique repressor role for certain C/EBPepsilon isoforms in the transcriptional regulation of a model eosinophil granulocyte gene, the major basic protein (MBP). The eosinophil-specific P2 promoter of the MBP gene contains GATA-1, C/EBP, and PU.1 consensus sites that bind these factors in nuclear extracts of the eosinophil myelocyte cell line, AML14.3D10. The promoter is transactivated by GATA-1 alone but is synergistically transactivated by low levels of PU.1 in the context of optimal levels of GATA-1. The C/EBPepsilon(27) isoform strongly represses GATA-1 activity and completely blocks GATA-1/PU.1 synergy. In vitro mutational analyses of the MBP-P2 promoter showed that both the GATA-1/PU.1 synergy, and repressor activity of C/EBPepsilon(27) are mediated via protein-protein interactions through the C/EBP and/or GATA-binding sites but not the PU.1 sites. Co-immunoprecipitations using lysates of AML14.3D10 eosinophils show that both C/EBPepsilon(32/30) and epsilon(27) physically interact in vivo with PU.1 and GATA-1, demonstrating functional interactions among these factors in eosinophil progenitors. Our findings identify novel combinatorial protein-protein interactions for GATA-1, PU.1, and C/EBPepsilon isoforms in eosinophil gene transcription that include GATA-1/PU.1 synergy and repressor activity for C/EBPepsilon(27).
