Summary
Direct contact with the toxic sap of the manzanilla tree (Hippomane mancinella) caused severe bullous dermatitis in a soldier. This common tropical tree poses a significant skin contact hazard, even from its leaves.
Area of Science:
- Dermatology
- Toxicology
- Botany
Background:
- Manzanilla tree (Hippomane mancinella) is a toxic plant found in tropical regions, known for its hazardous sap.
- The Euphorbiaceae family includes many toxic plants, with all parts of the manzanilla tree being poisonous.
Observation:
- A 37-year-old soldier developed blisters on his cheek within 30 minutes of a military exercise in Curaçao's mangroves.
- The bullous dermatitis was a direct result of contact with sap from the bark of a manzanilla tree.
Findings:
- The manzanilla tree's sap is a potent irritant, causing acute bullous dermatitis upon skin contact.
- Even environmental factors like raindrops falling from manzanilla leaves can induce similar skin reactions.
Implications:
- Awareness of the manzanilla tree's toxicity is crucial for individuals in endemic areas, especially during outdoor activities.
- Symptomatic treatment is typically effective, leading to dermatitis healing within weeks, but prevention is key.

Chromatin Structure Regulates pre-mRNA Processing
8.2K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

Spreading of Chromatin Modifications
9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Transcription Elongation Factors
13.9K
Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...

What are Second Messengers?
90.6K
Because many receptor binding ligands are hydrophilic, they do not cross the cell membrane and thus their message must be relayed to a second messenger on the inside. There are several second messenger pathways, each with their own way of relaying information. G-protein coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol path is active when the receptor induces phospholipase C to hydrolyze the phospholipid,...

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
