Question

Biology is often in news report. Write a latest issue of concern to you which is related to biology. Write an instance from news broadcast and review its link to biology. Explain in 1 to 2 paragraph.

Answer 1

ANSWER :-

1. Kidney is a vital organ that plays a vital role in ultrafiltration so as to remove waste from the body more specifically the nitrogenous compounds such as urea. Nephron is the functional unit of the kidney as it acts as the major filtration apparatus. Kidneys after embryonic development do not have the ability to regenerate and hence after any acute kidney injury or any disease associated with the organ, there are no chances of regeneration of the organ. This major concern has been reported to be faced only by using modern therapies more specifically regeneration therapies but many studies have restricted their research to animal models.
2. Some researchers from Saban Research Institute in Los Angeles have isolated specific type of cells which are considered to be the precursors for neurons. These were called as the Nephron Progenitor cells. These cells are present till around 32 to 34 week of development and their isolation have provided insights into the developmental pattern of the kidneys. Their research was associated with studying the pattern of a homeobox gene SIX2 which is involved in nephron morphogenesis and development. This gives a better tool for future regenerative therapies as a source to solve the problem of nephron regeneration.
