New Hope in the Fight Against Cancer: Scientists Discover Nutrient that Cancer Cells Crave

Arginine is an essential nutrient for cancer cells. Starving them could render tumors more vulnerable to the body’s natural immune response.

Cancer is one of the prominent causes of death globally, and discovering new methods to prevent and cure it is important for public health. Understanding the particular nutrients that cancer cells require is one of the strategies researchers are investigating to fight the disease.

Arginine is one of the important amino acids produced by our bodies naturally, and it is also abundantly found in food sources such as fish, meat, and nuts. According to the research published in Science Advances, cancer cells also need arginine to survive. It is possible to make tumors more susceptible to the body’s natural immune system and improve the effectiveness of treatment by depriving them of this nutrient.

The lack of this amino acid, which the researchers discovered to exist in various types of human cancers, forces the cancer cells to adapt. Cancer cells alter specific proteins to improve their ability to absorb arginine and other amino acids when their levels of that amino acid fall. Amazingly, these cells also induce mutations that lessen their reliance on arginine in an effort to keep growing.

Pictures I had forgotten I took.

Petri dish after being exposed to common household air. Includes Aspergillum, penicillium, green & black rhysopus, & stachybotrum moldm

close my eyes and make a wish i wanna live together in a petri dish!!!

FOTD #114 : purple brittlegill! (russula atropurpurea)

the purple brittlegill (also blackish-purple russula) is a mycorrhizal fungus in the family russulaceae. it grows with both coniferous & deciduous trees !! it has been recorded in europe, asia & eastern north america. :-)

the big question : can i bite it?? yes, though it's not particularly recommended. it is said to taste.. hot?

r. atropurpurea description :

"the cap is 4–10 cm (1.5–4 in) in diameter. it is dark reddish purple, with a dark; sometimes almost black centre. at first it is convex, but later flattens, & often has a shallow depression. it can also be lighter in colour, or mottled yellowish. the stem is firm, white, & turns grey with age. it measures 3–6 cm in length & 1–2 cm in diameter. the closely set and fairly broad gills are adnexed to almost free, & pale cream, giving a spore print of the same colour."

Ceratiomyxa fruticulosa var. poroides

by fungispot

i complain alot when it comes to uni and my course, but not gonna lie, here on my final year i've started to fall in love with it again, the way the fascination started when i was younger and learning new things was exciting.

throughout learning it always felt like i was not built for it, that I just cannot for the life of me focus and dedicate myself on anything. and i was just doubting myself and i should change courses or drop out because I was not meant to do this. and now on my second last semester, things kinda clicked. It may be hard for me to understand and learn, but it's worth it. To see the universe in all of its beauty, its ugliness, its complexity, its charm; it's a struggle but I'll endure it for you.

and I find myself really hoping I get to continue down in the stream of sciences and contribute to something for nature and for humanity as well, or at least deepen my understanding of how this universe works and widen my view of how intricate and special this world we live in actually is, how caring it is, how every single thing is worth something, and nothing from nature is ever truly useless

[March, 2023] culture stains & snow days

These pictures show PAS (purple/pink) and GMS (brown/blue) staining of a lymph node biopsy from a canine patient with lymphadenopathy and weight loss. Histology was suggestive of likely a fungal organism (bright pink in the PAS stain and dark brown/black in the GMS stain), however a mixed infection with an algal species could not be definitively ruled out without microbiology.

Our microbiologist cultured an Aspergillus species from this dog, and is in the process of ruling out any other possibilities.

What's especially cool is in one of the PAS pictures, you can see an organism trapped within an actively dividing macrophage!

Petri Dishes

Although they are scientific I think they make really cool art pieces i like to use them as reference images when practicing how to use colored pencils
