Selected Articles
1. The first complete mitochondrial genome of Curcuma amarissima (Zingiberaceae): insights into multi-branch structure, codon usage, and phylogenetic evolution.
Using both Nanopore and Illumina sequencing, the authors generated the first complete mitochondrial genome in Zingiberaceae, revealing a 6.5 Mb, 39-segment multi-branched architecture with weak codon usage bias and abundant repeats. The resource enables phylogenetic analyses and supports breeding, conservation, and molecular studies of Curcuma—relevant to botanical ingredients used in cosmetics.
Impact: This is a first-in-family genomic resource that will anchor phylogenomics and breeding strategies for Curcuma, a plant widely used in cosmetics and traditional medicine.
Clinical Implications: No direct clinical practice change; however, improved genomic resources can enhance traceability, quality control, and breeding of Curcuma-derived cosmetic ingredients.
Key Findings
- First complete mitochondrial genome in Zingiberaceae using combined Illumina and Nanopore sequencing
- Large, multi-branched mitogenome (6,505,655 bp; 39 segments) with 43 PCGs, 63 tRNAs, 4 rRNAs, GC 44.04%
- Weak codon usage bias and neutrality plot suggesting natural selection influences codon usage
- High repeat content potentially contributing to mitochondrial structural stability
- Phylogenetic analyses based on the mitogenome provide a framework for Zingiberaceae evolution
Methodological Strengths
- Hybrid long-read (Nanopore) and short-read (Illumina) assembly with annotation
- Comprehensive analyses including codon usage, RNA editing, repeats, and phylogeny
Limitations
- Single-species mitogenome; generalizability across Curcuma not established
- No functional validation linking structure to mitochondrial function or phenotype
Future Directions: Expand mitogenome sequencing across Curcuma/Zingiberaceae, integrate nuclear/chloroplast genomes, and functionally probe the roles of repeats and multi-branch architecture.
2. Deciphering the molecular mechanisms of oil palm lipid metabolism through combined metabolomics and transcriptomics.
Integrated LC–MS/MS metabolomics and transcriptomics across three developmental stages in two oil palm varieties identified 30 metabolites and 8,208 DEGs with stage-specific lipid changes. Correlation analyses pinpointed candidate genes in fatty acid synthesis, modification, and transport that may regulate lipid biosynthesis, informing breeding for oil yield and quality used in food and cosmetics.
Impact: By mapping gene–metabolite relationships underlying lipid biosynthesis, this study provides actionable targets for genetic improvement, directly relevant to optimizing oil profiles for cosmetics and food applications.
Clinical Implications: No immediate clinical impact; findings could guide selection and engineering of oil profiles that influence stability, texture, and tolerability in dermatologic and cosmetic formulations.
Key Findings
- LC–MS/MS lipidomics across 95, 125, and 185 days post-pollination identified 30 metabolites
- Transcriptomics revealed 8,208 differentially expressed genes between seedless (MS) and thin (MT) varieties
- Significant stage-specific changes in saturated and unsaturated fatty acids during fruit development
- Correlation analysis linked metabolites with gene expression, nominating genes in FA synthesis, modification, and transport
Methodological Strengths
- Integrated multi-omics design (LC–MS/MS metabolomics plus transcriptomics)
- Gene–metabolite correlation analyses to prioritize candidate regulators
Limitations
- Limited to two varieties and mesocarp tissue; environmental and genetic diversity not fully captured
- Correlative design without functional validation (e.g., gene editing or transgenics)
Future Directions: Functionally validate candidate genes (e.g., CRISPR), expand to diverse germplasm and environments, and link lipid profiles to product performance in food/cosmetic applications.
3. Evaluation of topical vitamin k cream on repair of full thickness wound in diabetic rat.
In a randomized diabetic rat model (n=75), topical 1% vitamin K increased hydroxyproline and collagen and improved oxidative (e.g., GSH, SOD, GPX) and inflammatory (lower TNF-α, IL-1β) markers versus control, with histologic support. The text notes larger wound areas in active groups at all time points, which conflicts with the healing conclusion and warrants clarification.
Impact: Suggests an inexpensive, widely available topical agent that may enhance wound healing biomarkers in diabetic wounds, a high-burden condition in dermatology and wound care.
Clinical Implications: Preclinical data support exploring topical vitamin K in early-phase human studies for diabetic wound care; however, inconsistencies in wound area reporting require resolution before clinical translation.
Key Findings
- Randomized allocation of 75 diabetic rats into five treatment arms including 1% vitamin K cream
- 1% vitamin K and phenytoin increased hydroxyproline and collagen compared with control
- Improved oxidative stress (↑GSH, SOD, GPX; ↓MDA) and reduced inflammatory markers (↓TNF-α, ↓IL-1β)
- Histopathology corroborated biochemical improvements; reported wound area findings conflict with healing interpretation
Methodological Strengths
- Randomized design with adequate group sizes (n=15 per arm) and multi-timepoint assessment
- Multimodal endpoints: morphometry, biochemistry (oxidative/inflammatory markers), and histopathology
Limitations
- Preclinical animal model limits generalizability to humans
- Textual inconsistency regarding wound area trajectories; blinding and allocation concealment not reported
Future Directions: Clarify wound area outcomes, standardize blinding, and conduct dose-ranging and early-phase clinical trials to evaluate efficacy and safety in diabetic wound care.
