It has been implicated in addictions to alcohol, cannabinoids, cocaine, methylphenidate, nicotine, opioids, phencyclidine, propofol, and substituted amphetamines, among others.ΔJunD, a transcription factor, and G9a, a histone methyltransferase enzyme, both oppose the function of ΔFosB and inhibit increases in its expression. Sufficiently overexpressing ΔJunD in the nucleus accumbens with viral vectors can completely block many of the neural and behavioral alterations seen in chronic drug abuse (i.e., the alterations mediated by ΔFosB). Similarly, accumbal G9a hyperexpression results in markedly increased histone 3 lysine residue 9 dimethylation (H3K9me2) and blocks the induction of ΔFosB-mediated neural and behavioral plasticity by chronic drug use, which occurs via H3K9me2-mediated repression of transcription factors for ΔFosB and H3K9me2-mediated repression of various ΔFosB transcriptional targets (e.g., CDK5). ΔFosB also plays an important role in regulating behavioral responses to natural rewards, such as palatable food, sex, and exercise. Since both natural rewards and addictive drugs induce the expression of ΔFosB (i.e., they cause the brain to produce more of it), chronic acquisition of these rewards can result in a similar pathological state of addiction. Consequently, ΔFosB is the most significant factor involved in both amphetamine addiction and amphetamine-induced sexual addictions, which are compulsive sexual behaviors that result from excessive sexual activity and amphetamine use. These sexual addictions are associated with a dopamine dysregulation syndrome which occurs in some patients taking dopaminergic drugs.The effects of amphetamine on gene regulation are both dose- and route-dependent.
In another study involving 63 patients aged less than twelve years, children had an average of 5.33 bleedings per year after using turoctocog alfa as hemophilia treatment. In this study too turoctocog alfa was considered as an excellent treatment for 116 out of 126 bleeding episodes.Alongside the benefits, a few of the common turoctocog alfa adverse effects would be injection site reaction, pyrexia and augmented liver enzyme levels. Rare cases of allergic reactions have been reported as well. There is a possibility of patients developing hypersensitivity to the drug since it contains traces of hamster proteins. Activity-neutralising antibodies may be developed whereby expected plasma factor VIII activity levels may not be achieved and thus the bleeding would not be controlled as needed. Preparation
As cell culture, Chinese hamster ovary cells (CHO) are used in order to acquire proper processing of factor VIII protein, that has demonstrated good efficacy in thrombin generation and clot formation in preclinical evaluations in murine (mouse) and canine (dog) models of hemophilia A and in patient-derived whole blood. Difference between NovoSeven and NovoEight
Even though both treatments are plasma-derived and recombinant analogues of blood clotting factors, NovoSeven is developed as a congenital FVIIa analogue for hemophilia A and B patients while NovoEight (turoctocog alfa) is for congenital FVIII deficiency. NovoSeven is called a bypassing agent because it skips the need for factor VIII or IX in people with inhibitors and activates factor X directly.
