For over 15 years, Dr Anthony Shum, a pulmonologist at the University of California, San Francisco has been studying a rare genetic disorder called the COPA Syndrome. It stands for coatomer subunit alpha and is a rare, inherited disorder that affects the lungs, joint, and kidney. The National Organization for Rare Disorder also notes that it is a genetic autoimmune disorder that is caused by mutations in the COPA gene. This disease affects families unpredictably—some individuals with the mutation develop severe lung damage early in life, while others remain completely healthy. Now, Shum’s team has discovered a protective genetic variant that may offer new hope for treatment.

A Breakthrough

Researchers found that some relatives of COPA Syndrome patients stayed healthy despite carrying the same COPA gene mutation that causes the disease. The key difference? These unaffected individuals had a protective version of another gene called HAQ-STING.

When scientists introduced HAQ-STING into diseased lung cells from COPA patients, the cells returned to a balanced state, suggesting that this gene could be used as a therapy.

“We really think HAQ-STING could be a gene therapy tool and a step toward a cure,” said Shum, whose findings were published in the Journal of Experimental Medicine.

Families Who Solved The Mystery

Shum’s journey into COPA Syndrome research began in 2011 when he treated a young woman, Letasha, who had severe lung bleeding. Her mother, Betty Towe, mentioned that Letasha’s sister, Kristina, had suffered from similar symptoms. Over the years, Betty had taken both daughters on a four-hour trip to UCSF for treatment. After tracing their family history, Shum discovered that their distant relatives in Texas and Oakland also had lung problems and arthritis. In 2015, Shum, along with scientists from Baylor College of Medicine and Texas Children’s Hospital identified the COPA gene mutation. They realized that it was the common factor behind the illness. However, only some of the 30 individuals with the mutation actually developed symptoms, leaving a major question unanswered.

The Domino Effect

It was established that it occurs when a mutated COPA gene causes another gene STING to go overdrive. The STING that helps fight infections in COPA patients, remain permanently active, which leads to chronic inflammation that damages the lungs, kidneys, and joints. In 2020, while studying STING’s role in the disease, researchers discovered a key variation: HAQ-STING. This version of STING, present in about one-third of the population, appeared to neutralize the harmful effects of the COPA mutation.

To confirm their theory, the scientists needed both affected and unaffected family members to participate in the testing. Letasha, Kristina and Betty immediately volunteered. The researchers then analyzed DNA samples from 26 COPA patients and their healthy relatives. They also conducted CT scans and blood tests to ensure that unaffected members did not have any hidden symptoms. When the findings were all clear, it was revealed that all the healthy individuals had HAQ-STING, while none of the COPA patients did. This was the first known case of a common gene variant completely protecting against a severe genetic disease.

Encouraged by this discovery, researchers tested HAQ-STING’s effects in a lab setting. They introduced it into diseased lung cells from COPA patients, and the cells returned to normal function.

Way Ahead

Shum believes HAQ-STING could lead to game-changing treatments, including:

  • Prenatal gene therapy for babies diagnosed with COPA Syndrome before birth
  • Aerosol delivery of HAQ-STING for adults, directly targeting the lungs

Before publishing their findings, Shum called Betty with the news—her own HAQ-STING gene had protected her from the disease. He also informed Letasha and Kristina, who were overwhelmed with relief and joy.

“We always believed Dr. Shum would get to the bottom of it,” said Letasha. “This discovery is going to change lives.”

Glucagon-like peptide-1 (GLP-1) receptor agonists, such as Ozempic and Mounjaro, are best known for treating type 2 diabetes and obesity. However, a new study published in The BMJ suggests that people with diabetes using these blockbuster drugs may have an increased risk of hair loss (alopecia).

While the absolute risk is low, researchers from the University of Pennsylvania and the University of Southern California identified alopecia as a possible side effect of GLP-1 receptor agonists, particularly semaglutide and tirzepatide.

“GLP-1 receptor agonist use was associated with a higher risk of clinically recorded alopecia, particularly non-scarring alopecia, in patients with type 2 diabetes, compared with SGLT-2 and DPP-4 inhibitors,” the researchers wrote.

Non-scarring alopecia is a type of hair loss in which the hair follicles remain intact, making hair regrowth possible.

The researchers said the findings could help inform shared decision-making when considering GLP-1 receptor agonist therapy and highlight the need for further research into dermatological outcomes.

What Did The Study Find?

Researchers analyzed health data from 12,004 patients using GLP-1 receptor agonists and compared them with 15,221 patients using SGLT-2 inhibitors between January 2019 and September 2024. They also compared another 11,964 GLP-1 receptor agonist users with 11,233 DPP-4 inhibitor users.

The study found that adults using GLP-1 receptor agonists had:

  • A 37% higher risk of alopecia than SGLT-2 inhibitor users (6.91 vs. 5.04 per 1,000 person-years).
  • A 68% higher risk of alopecia than DPP-4 inhibitor users (6.53 vs. 3.89 per 1,000 person-years).

Further analyses showed the association was specific to non-scarring alopecia, with a 53% higher risk compared with SGLT-2 inhibitors and a 72% higher risk compared with DPP-4 inhibitors.

Why GLP-1 Drugs Are Linked to Hair Loss?

The researchers noted that rapid weight loss is a well-established trigger of hair shedding and may also lead to iron or zinc deficiencies, disrupting the hair growth cycle.

They added that hormonal changes may also play a role, although further studies are needed to understand the underlying mechanisms.

What Are the Study's Limitations?

The researchers acknowledged that they could not assess the severity, extent, duration, or reversibility of alopecia after treatment was stopped because of limited clinical information. They also could not rule out the influence of other unmeasured factors.

However, they said the study was based on high-quality data from a large, representative cohort, and the findings remained consistent across additional analyses.

“Our findings extend previous anecdotal safety signals and provide more systematic evidence to inform clinical awareness of this potential adverse effect,” the researchers concluded.

What To Do If You're Losing Hair on Ozempic, Mounjaro?

If you're experiencing excessive hair shedding while taking semaglutide, you may consider:

  • Discussing with your physician whether your dosage should be adjusted or whether nutritional supplements may help.
  • Increasing your protein intake to at least 100 grams per day.
  • Taking hair-supporting nutrients such as biotin, vitamin D, iron, and zinc.
  • Using topical treatments such as minoxidil to support hair regrowth.
  • Avoiding severe calorie restriction and maintaining a nutritionally balanced diet.

The Overlooked Health Conditions Affecting Women During Their Most Productive Working Years

Updated Jul 23, 2026 | 12:49 PM IST

SummaryThe early signs of some autoimmune and chronic conditions tend to be so mild and easy to explain away that most women simply put them down to stress, lack of sleep, or an overly full plate.

Between climbing the career ladder, raising kids, and keeping everything else running smoothly, there's rarely a spare moment when women should stop and check in with their own bodies.

Yet these same demanding years are often when certain autoimmune and chronic conditions first start to surface. The early signs tend to be so mild and easy to explain away that most women simply put them down to stress, lack of sleep, or an overly full plate.

Some of the autoimmune conditions that commonly fly under the radar include:

· Lupus

· Rheumatoid arthritis

· Sjogren’s syndrome

· Systemic sclerosis

· Psoriatic arthritis

Family history matters more than most women realize. Autoimmune conditions often have a genetic component, and having a parent, sibling, or close relative with an autoimmune disorder meaningfully raises the likelihood of developing one yourself, even if the specific condition isn't identical. If this applies to a woman, the symptoms below deserve even closer attention and a lower threshold for seeking medical advice, rather than waiting to see if they resolve on their own.

So, when should women get it checked? If any of these symptoms stick around rather than passing after a good night's sleep, it's worth paying attention:

· Fatigue that doesn't go away no matter how much rest you get

· Joint pain or stiffness, especially in the morning

· Unexplained aches in your muscles

· Skin rashes or a new sensitivity to sunlight

· Sudden shifts in your weight or energy levels

It is advised not to dismiss them, particularly if they've been going on for a few weeks. Early detection changes everything. It is observed that the difference between a manageable condition and a complicated one often comes down to how soon it was caught.

Diagnose early, and treatment can be initiated before the disease has a chance to progress, allowing a patient to continue living life on her own terms, not one dictated by illness.

That said, the fundamentals of good health have never changed, and we continue to emphasize routine check-ups, a balanced diet, adequate sleep, regular physical activity, and sound stress management. But if there is one thing every woman should take seriously, it is to learn to listen to your own body.

You know it better than anyone else. If something feels different, do not dismiss it or wait it out; seek an opinion. Awareness combined with timely action is what ultimately allows a woman to lead a full, active life both professionally and personally, well into her later years.

'X-Men' Star Tyler Mane Shares Male Breast Cancer Treatment Journey, Urges Men To Prioritize Health

Updated Jul 23, 2026 | 11:10 AM IST

SummaryTyler Mane is currently undergoing four rounds of chemotherapy followed by localized radiation therapy. The actor is encouraging men to pay attention to their health, have open conversations about family medical history, and never ignore unusual symptoms.

In June, X-Men actor and former professional wrestler Tyler Mane revealed that he had been diagnosed with a "super-rare" form of breast cancer. The disease is uncommon in men, accounting for only about 1% of all breast cancer cases.

Now, as he undergoes treatment, the actor is encouraging men to pay attention to their health, have open conversations about family medical history, and never ignore unusual symptoms.

A Lump That Changed Everything

As he lost weight, he noticed a lump in his breast. Initially, he did not think it was serious and had it removed. However, laboratory tests revealed it was invasive ductal carcinoma, the most common form of breast cancer.

Following the diagnosis, Mane underwent genetic testing, where he found that he carries the BRCA2 gene mutation. The mutation significantly increases the risk of developing several cancers, including breast, prostate, pancreatic and, in women, ovarian cancer.

The discovery also made him realize how little he had discussed health issues with the men in his family.

Mane Had Breast Cancer Stage 1

Although the cancer was caught early, doctors determined it was aggressive enough to require chemotherapy after surgery.

"I was lucky enough that my breast cancer was stage 1. Men usually don't notice the signs or don't quickly treat breast cancer. By the time it's diagnosed, it is often stage 3 or 4, metastasized throughout their bodies, and then it becomes a whole different thing," he wrote in an interview with Yahoo.

Mane explained that the tumor measured 28 millimeters and had a surgical margin of less than one millimeter, making additional treatment like chemotherapy and radiation necessary.

The actor added that genomic testing showed a high risk of recurrence without treatment.

'Chemotherapy Is Not Fun'

Mane is currently undergoing four rounds of chemotherapy followed by localized radiation therapy.

"I'm being treated with four rounds of chemo, and then I have to have some localized radiation treatment to make sure the cancer is all wiped out."

While treatment has been challenging, he said it is essential. "And let me tell you: Chemotherapy is not fun. But it is a necessity."

He also describing its side effects such as 'metal taste' hair loss and fatigue.

"They give you some really good steroids for the day before, the day of and the day after chemotherapy. But then when that wears off, it all kind of hits you. You get the metal taste in your mouth. You feel sluggish and want to sleep all the time. My beard fell out. I look like a hairless cat with a couple of tufts on my face now".

Learning To Slow Down During Treatment

The actor admitted he initially underestimated the impact chemotherapy would have on his body. He also realized he had pushed himself too hard physically in an effort to stay strong.

Now, he is focusing on maintaining his strength by increasing his protein intake while continuing moderate exercise.

"Physically, I'm trying to keep up my protein intake to help me stay strong throughout treatment."

Despite the challenges, Mane has continued a daily workout routine that includes push-ups, squats and rebounding exercises.

Message For Men

Through his public updates and the podcast Mane hopes to raise awareness that breast cancer is not exclusively a women's disease. By sharing his experience, he wants more men to recognize the symptoms early, discuss their family medical history, and seek medical attention without delay.
