Proline Metabolism of Different Varieties of Hami Melon Fruits in Response to Low Temperature [PDF]

Shipin Kexue
In order to investigate the change in proline metabolism of two varieties of Hami melon fruits during low-temperature storage, ‘Xizhoumi 25’ and ‘Gashi’ melons were pre-cooled for 24 h and then placed for up to 42 days in a mechanical cold storage at (3 ...

Life Factors and Melanoma: From the Macroscopic State to the Molecular Mechanism

Advanced Science, Volume 12, Issue 43, November 20, 2025.
Melanoma, an aggressive skin cancer, arises from dynamic interactions between genetic, environmental, and lifestyle factors. This review explores how age, gender, obesity, diet, exercise, smoking, alcohol, UV exposure, circadian rhythms, and medications influence melanoma risk and progression.

Proline Protects Boar Sperm against Oxidative Stress through Proline Dehydrogenase-Mediated Metabolism and the Amine Structure of Pyrrolidine

Animals, 2020
Proline was reported to improve sperm quality in rams, stallions, cynomolgus monkeys, donkeys, and canines during cryopreservation. However, the underlying mechanism remains unclear.

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

Acta Ophthalmologica, Volume 103, Issue 7, Page e436-e455, November 2025.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.

Structure of the proline dehydrogenase domain of the multifunctional PutA flavoprotein [PDF]

, 2003
The PutA flavoprotein from Escherichia coli plays multiple roles in proline catabolism by functioning as a membrane-associated bi-functional enzyme and a transcriptional repressor of proline utilization genes.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce
