factors that include transcription factors, nuclear receptors, and other epigenetic modifier genes. • Based on data of siRNA knockdown or enforced expression. Targeting of the same HDAC can have different biological effects depending on the cellular context. • Expression level of HDAC1 in primary human gastric cancer tissues through semi-quantitative RT-PCR and immunoblot analysis. The expression level of HDAC1 was compared in paired normal and GC tissues. The expression pattern was also topologically

The use of non-human animals in controlled variable experiments that affect the behaviour or biological systems of such animals is the very definition of animal testing. Animal testing has always been a controversial subject: be it within the bounds of medicinal advancement, cosmetic research, or even in the pursuit of scientific knowledge. Many animal rights advocates and societies, such as PETA (People for the Ethical Treatment of Animals) and BUAV (British Union for the Abolishment of Vivisection)

The Fluidity of Neuroscience Gender Norms & Racial Bias in the Study of the Modern "Neuroscience" Neuroscience is the scientific study of the nervous system. Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. The term neurobiology is usually

child. But one summer day, as he and his colleague Roberto Lizarralde lounged around in hammocks, chatting with Rachel, an elderly woman of the Barí tribe of Venezuela, she pointed out his error. Babies, she explained, can easily have more than one biological father. "My first husband was the father of my first child, my second child, and my third child," Rachel said, recalling her life. "But the fourth child, actually, he has two fathers." It was clear that Rachel didn't mean there was a stepfather
