The researchers discovered that the absence of the AMBRA1 protein can promote tumour growth in mice and is associated with less favourable prognoses in several types of human malignancies.
What does AMBRA1 do?The researchers demonstrated that AMBRA1 functions as a critical tumour suppressor, as these molecules are frequently referred to in healthy cells, by suppressing tumour growth. The latest research demonstrates that AMBRA1 targets additional proteins that aid in cell division for destruction when cell division is not required.The latest findings may provide potential methods for preventing the out-of-control cell division brought on by the loss of AMBRA1 and for making cancer cells more susceptible to CDK4/6 inhibitors.The topic of whether AMBRA1 is involved in cancer was raised by the revelation that AMBRA1 aids in the regulation of cyclins and, consequently, cell division. Low levels of AMBRA1 were discovered by the researchers to be a marker of poor outcomes for individuals with a variety of cancer types using data gathered by The Cancer Genome Atlas (TCGA).To learn more about tumour refer :

Platelets are fragments of larger cells and normally circulate in the blood without adhering to blood vessel walls. When the wall of a blood vessel is damaged, collagen fibers in the wall are exposed to the interior of the blood vessel. The exposed fibers and chemicals released from the endothelial cells that line the blood vessel attract platelets, which start to form a plug and release other chemicals (Figure 1).
Which of the following best explains the feedback mechanism illustrated in Figure 1?
a. This is an example of positive feedback, because the few platelets that initially bind attract more platelets to the damaged area.
b. This is an example of positive feedback, because it results from the interactions among collagen, endothelial cells, and platelets.
c. This is an example of negative feedback, because a large clump of platelets can block the blood vessel and prevent blood flow through it.

Antibodies and proteins shield you from harmful chemicals when they come into touch with your body. Antibodies are created by your immune system to bind to these foreign chemicals and remove them from your body. Immunoglobulin is another term for an antibody. A foreign substance that enters your body is referred to as an antigen. This includes venom, allergens, bacteria, viruses, fungus, and other poisons. Your immune system makes an antibody protein that it employs to find and eliminate particular antigen. Surface molecules on antigens are different from ones your body typically produces. Your immune system thus recognizes an antigen as soon as it enters your body. Your immune system requests antibody defense in order to fight against this antigen invasion.

Chemical damage (particles that can modify the structure of DNA or the base pair bonding) and radiation damage (UV radiation is known to create mutations known as thymine dimers) are two different ways that DNA can become genetically altered. Two thymine molecules on the same strand link together to cause these mutations, which change the structure of the DNA molecule. T=T can also be used to represent this.

Anatomically, the precentral gyrus houses the primary motor cortex, which controls free will movement. The temporal lobe, which is found behind the ears, is the second-largest lobe. The internal occipital lobe is separated from the parietal and internal temporal lobes by the parieto-occipital sulcus, a very deep sulcus that runs through the posterior region of the hemisphere.
The insula plays a crucial role in the processing of gustatory and sensorimotor information, risk-reward behavior, autonomic nervous system function, pain pathways, and auditory and vestibular functions.
The main somatosensory cortex, a prominent brain area in charge of proprioception, is located in the postcentral gyrus. On the lateral and medial surfaces of the cerebral hemispheres, the central sulcus serves as the dividing line between the frontal and parietal lobes.
