Source:
Type:
Poly (ADP-ribose) polymerase (PARP) cleavage is a hallmark of caspase activation. PARP (Poly (ADP-ribose) polymerase) is a family of proteins involved in a variety of cellular processes, including DNA repair, genomic stability, and programmed cell death. PARP enzymes play a crucial role in repairing single-strand breaks in DNA.
PARP has gained significant attention, particularly in the treatment of certain types of tumors, such as those with BRCA1 or BRCA2 mutations. These mutations impair the cell's ability to repair double-strand breaks in DNA through homologous recombination. Cancer cells with these mutations can become reliant on PARP for survival, making them particularly sensitive to PARP inhibitors.
PARP inhibitors, such as olaparib, rucaparib, and niraparib, have been developed as targeted therapies for cancers associated with BRCA mutations.

PARP Family:
The poly (ADP-ribose) polymerases (PARPs) are a family of enzymes involved in a number of cellular processes, including DNA repair, genomic stability, and programmed cell death.
PARP1 is the predominant family member responsible for detecting DNA strand breaks and initiating repair processes, especially through base excision repair (BER).

PARP1 Overexpression:
In several cancer types—including breast, ovarian, prostate, and lung cancers—elevated PARP1 expression and/or activity has been reported.
High PARP1 expression in certain cancers has been associated with aggressive tumor behavior and resistance to therapies (especially those that induce DNA damage).
Increased PARP1 activity may correlate with poorer overall survival in tumors that rely on DNA repair for survival.

Psoriasis is an autoimmune skin disease.
This section mainly deals with PsA which is psoriatic arthritis

PsA evidence based approach

Rank Approach Evidence Mechanism / Rationale Notes
1 Weight loss if overweight/obese Best direct evidence in PsA Reduces metabolic inflammation, adipokine burden, and joint inflammatory load; may improve treatment response. Highest-yield natural strategy when excess weight is present.
2 Regular exercise / physical activity Good supportive evidence Improves pain, stiffness, function, fatigue, muscle support, and cardiometabolic health. Strong adjunct for joint symptoms and overall health.
3 Mediterranean-style diet / antioxidant-rich whole-food diet Moderate evidence May reduce systemic inflammatory tone; provides polyphenols, fiber, unsaturated fats, and better metabolic support. Best antioxidant strategy is diet pattern rather than antioxidant pills.
4 Intermittent fasting / time-restricted eating Early limited evidence May improve inflammatory signaling and metabolic regulation; possible benefit for CRP, enthesitis, and disease activity. Promising but still exploratory.
5 Omega-3 (fish / fish oil) Mixed evidence Shifts eicosanoids toward less inflammatory profiles and may modestly reduce inflammatory tone. Reasonable adjunct, but not a top-tier PsA joint intervention.
6 Vitamin D Weak PsA-specific treatment evidence More relevant for deficiency correction, bone support, and immune modulation than for direct joint control. Most relevant when levels are low.

PsA pathways to modulate

Rank Pathway / Axis Why It Matters in PsA Joints Helpful Modulation Support Level
1 IL-23 → Th17/Tc17 → IL-17A/F Core inflammatory axis in psoriatic arthritis; active in synovium, enthesis, and related tissues. Reduce excessive IL-23 / IL-17 signaling and downstream cytokine/chemokine output. Very high
2 TNF-α / NF-κB inflammatory axis Major validated cytokine pathway driving inflammation, tissue injury, and amplification of disease activity. Reduce TNF / NF-κB-driven inflammatory signaling and matrix damage. Very high
3 JAK / STAT3 signaling Supports cytokine signaling relevant to synovial and entheseal inflammation. Dampen excessive JAK / STAT3 inflammatory activity. High
4 Myeloid / inflammasome amplification (IL-1β, IL-6, GM-CSF) Amplifies synovitis, pain, recruitment of inflammatory cells, and osteoclastogenic signaling. Reduce IL-1β, IL-6, and GM-CSF inflammatory amplification. High
5 RANKL / M-CSF / osteoclastogenesis Important for bone erosions and osteoclast-mediated damage. Reduce osteoclast differentiation and bone resorption pressure. High
6 DKK1 / Wnt / BMP bone-remodeling balance PsA involves both erosions and abnormal new bone formation. Rebalance remodeling rather than simply suppress all bone formation. Moderate to high
7 COX-2 / 5-LOX / eicosanoid signaling Contributes to inflammatory pain, swelling, and leukocyte recruitment. Reduce excess prostaglandin and leukotriene inflammatory tone. Moderate
8 KEAP1-NRF2 / oxidative stress-redox balance Oxidative imbalance may reinforce inflammatory signaling and tissue injury. Improve antioxidant defense and redox resilience. Moderate
9 Obesity / adipokine / metabolic inflammation axis Obesity is linked to worse disease activity and poorer response. Reduce metabolic inflammation and adverse adipokine signaling. Moderate
10 Gut microbiome / barrier / immune-metabolite axis Gut dysbiosis and barrier changes may influence systemic immune activation. Support gut barrier function and more favorable immune-metabolic signaling. Moderate

Natural products that might help PsA — mechanistic HTML table

Natural Product / Class Main PsA-Relevant Pathways Mechanistic Rationale Direct PsA Joint Evidence Practical Read
Omega-3 (EPA/DHA) IL-17-related signaling; TNF/NF-κB tone; eicosanoids / resolution pathways May shift lipid mediators toward less inflammatory profiles and reduce inflammatory signaling. Mixed / weak Most practical food/supplement adjunct, but not a strong standalone PsA joint therapy.
Curcumin / Turmeric NF-κB; JAK/STAT3; MAPK; IL-17 / IFN-γ; redox signaling Broad anti-inflammatory and signaling-modulating effects relevant to psoriatic disease biology. Very limited direct evidence Reasonable mechanistic adjunct; stronger biology than clinical PsA proof.
Boswellia / Boswellic acids 5-LOX; NF-κB; COX-2; leukotrienes Notable leukotriene / 5-LOX angle with broader anti-inflammatory effects. No strong direct PsA joint trials Plausible adjunct, especially for eicosanoid-driven inflammation.
Ginger NF-κB; COX / LOX; inflammatory pain pathways Anti-inflammatory and antioxidant actions with arthritis-relevant pathway effects. Indirect only Plausible low-to-moderate adjunct; evidence is not PsA-specific.
EGCG / Green tea catechins IL-17 / IL-23-related inflammation; oxidative stress; keratinocyte hyperproliferation Immune-regulatory and antioxidant effects; mainly supported in psoriasis/preclinical models. Mostly psoriasis / preclinical Interesting adjunct, but not proven for PsA joints.
Sulforaphane KEAP1-NRF2; oxidative stress; TH17-related inflammation; autoimmune signaling Strong redox / NRF2 rationale with anti-inflammatory effects in preclinical models. Preclinical / indirect Good mechanistic candidate for the NRF2-redox tier.
Quercetin NF-κB; PI3K/AKT/GLUT1; inflammatory cell signaling Multi-target anti-inflammatory effects with arthritis relevance. Weak direct PsA evidence Mechanistically attractive, clinically still speculative for PsA.
Resveratrol NF-κB; oxidative stress; inflammatory mediators; SIRT1/AMPK-linked effects May reduce inflammatory signaling and support metabolic/redox regulation. Very limited for PsA Interesting but not near the top for real-world PsA use.
Piperlongumine NLRP3 inflammasome; ROS-sensitive inflammatory signaling; FLS proliferation/migration; MMPs Research-stage anti-inflammatory candidate with RA/psoriasis-model relevance. Research-stage only Experimental; not a practical PsA supplement at present.
Shikonin JAK/STAT; TNF-driven synoviocyte signaling; macrophage polarization; psoriasis inflammation Biologically interesting for synovitis and immune-cell signaling. Research-stage only Experimental; mainly of mechanistic interest.
